It funny, there is no mention of drilling one of the seat back channels into place with the seat back. And when I say no mention... nothing the manual, nothing in the HBH videos, nothing in the Matronics archives. Here is a method for drilling 7F6-5 into place that I used:

First, finding the notes in the plans was hard, so it is A4, pitch 40.

Don't worry about drilling it into the extrusion gusset yet. Draw your centerline on the flange that meets the seat back and push into place. I had one hole on the side extrusion that I had to match, but you are lucky you can just drill the flange into the uprights. Once the back support is positioned, extend the center line onto the uprights.

Cleco the seat back into place over 7F6-5. Now extend the centerline from the uprights onto the seat back. Now space your rivets making sure to take into account where the vertical ("L") will go in the seat back.

I drilled four test holes to make sure I had extended the line properly, which I had. The remaining holes were then drilled.

I also had to trim the bottom tabs of the engine mount for a good fit. Sadly the radius bend in the lower mount is causing fit issues. the solution may be shims, grinding away part of the frame rails, or both.

Here are some pictures detailing the issue.

More stuff that has gotten done:

1) Trimmed and readied the cross wise fuselage tube. The holes are close together, but I over estimated the spacing on the aft side. If the spacing is too close for me when the holes are drilled out, then I will fabricate a new gusset and new tube and use that extra spacing.
2) Drilled the bottom fuselage tube gussets into place.
3) Fabricated the fuselage side extrusion gussets.
4) Trimmed the uprights to clear the gussets.
6) Drilled the fuselage extrusion gussets into place.
7) Drilled the fuselage extrusion into place.

On the pilot side the fuselage extrusion was trimmed 8mm too much and could not be placed to tie into the rear uprights. I am considering making a gusset out of 0.080 that would then tie the extrusion into uprights.

Several short building sessions worth about 10 hours:

1) Built the wing pickup templates ( go slow and get this right! )
2) Did more trimming to the fuselage side extrusion
3) Trimmed the fuselage tubing
4) Fabricated a Festivus pole, burning out the Dremel
5) Fitted the fuselage frame together with the front and rear. This required taking the fuselage and wings into our front yard... in view of the street. Several people walked by not even looking.
6) Test fitted the wings together with the fuselage.

All the work was easy, but stuff that you want to get right. When making the wing pickup templates test fit them from the top of the template to ensure the fit. The entire template can not be shoved into the wing root since the template front is cut at an angle.

Friday night two hours were spent installing the grommets in the fuselage front and riveting the doublers and front together with the forward fuselage. The first attempts to align the rear and front fuselage were also made. The flaperon stop fabrication was finished and a few initial holes were made to join the firewall to the bottom fuselage skins.

Sunday night we finished joining the forward and rear fuselage halves along the the bottom seem. This took a great deal of time adjusting making sure that the front and rear were straight with each other.

To make the job easier we raised the entire fuselage up using steel beams and then drilled several holes on each side with the angle drill after the alignment was completed. The fuselage was then pulled forward off the table ( still using beams to support it ) so I could reach under and drill all the remaining holes.

While preparing the start work with 7F12-1, I got out the new engine mount that Zenith provided along with the remaining steal tube frame and started test fitting them. While the engine mount mostly fit on the firewall, much to my horror the middle side mounts are below the flange of the channel by about 10mm. My first thought was that the channel was up too high, but the gear strut is in perfect alignment and length with it, I measure carefully AND the other flange interferes with the engine mount. The upper tubes of the mount descend relative to the fuselage, but in order for the tubes to clear the channel they would have to ascend.

Hopefully Roger or Caleb will have an answer. My advice for the moment would be to make sure you have the engine mount before starting the firewall and to use it to confirm clearance, fit and placement of all the firewall parts before drilling.

Update:

So before contacting Zenith I realized I should check the builder's area of the 701 site. Right there was a new updated builder's manual section for the new engine mounts. It turns out that the middle mounts are not intended to join the firewall at the channel, and the bottom mount needs to be trimmed to an angle so they attach below the longerons, which should place the middle mounts exactly where they should be.

Friday night we spent two hours drilling out the remaining holes, fabricating 7F11-8 ( float reinforcement plate ) and priming the parts.

Saturday night we riveted most of the forward fuselage together. I opted not to rivet the seat front yet since I have still not bought the grommets or fitted the fairlead. The flap stop also was not riveted.

Properly riveting the longerons was challenging due to the size of the flange. Luckily the metal was still thin enough to allow the riveter head to push in and become flush.

After the riveting was done I did a test fit between the forward and rear fuselage. The obtain a good fit the uprights had to be trimmed and the extrusion that is part of the side skins required additional trimming. Of course the doors had to be put in their approximate place along with the firewall.

The bigger effort was taking care of the flooding that took place. The driveway and workshops drains clogged with silt, causing several inches of standing water.

Monday Night: I spent about three hours carefully trimming and adjusting the torque tunnel. From my previous session I thought the piece was ready, but after attempting a true fit it became apparent that the piece from Zenith was too large. It took slow and careful attention to trim the sides evenly so as to obtain the correct height and keep the edges along the predetermined lines.

Sunday we spent about three hours getting the forward half of the fuselage ready to join the rear half.

The seat front doubler is now ready for the grommets and fair leads. The rear floor stiffener is in place, and the torque tube bearings were fabricated. By using some pieces of wood, I was able to position the bearings with the torque tube in place for a more accurate fit. Also the tube tunnel was trimmed and is now ready to be drilled into place.

Saturday night started with drilling the side skins into place. The forward fuselage was disassembled and the center stiffener was drilled into place. After putting the floor skins back together the longeron extrusions were cut and drilled into place. After that the side skins were put back on and I back drilled through the longerons.

Tip: I made the mistake of drilling the hole where the rear gear channel and longerons meet. When the side skin got put back on this became a problem. To get the holes to match, I back drilled from the top into the side skins and then found the longeron hole with the cleco.

I also started working on the rear and forward stiffeners. I found that the existing pre-drilled holes are too close together OR the floor stiffener was not made tight enough. To work around this extra care was taken to center the forward stiffener. I also found that the rear stiffener needed trimming to fit and not rub.

In addition to the building of materials, I built some time. My log book is now the proud owner of more than 20 hours of ASES.

I spent four hours on the floor pan. The first holes joining the side skins and bottom skins have been made.

It took a god bit of effort to get the skins to fit properly. First some trimming had to be done on seat front to allow the skins to sit flush. Also a good bit of time was spent on the jigs so the rear and front halves of the fuselage will join properly. And finally, there were some edge distance issues between the bottom of the side skins and the bottom skins.

Despite being drilled together, there is still some play between the width of the side skins where the strut supports are clecoed on.

I spent about 4 hours Wednesday night working on the fire wall. The hardest part is making sure that the strut is aligned and not rubbing against other metal. I had to open up the holes to get a good fit.

The lower bearing halves are drilled out to 3/16", but are still too tight to fit the AN3 bolts required, so I'll have to grab some reamers.

Tuesday I grabbed one of Kenmore's Super Cubs and took it for a spin up to Lake Isabel. Going any later in the year will be impossible thanks to the ice that will form. The story is that about 10 years ago Kenmore had a 172 that got stuck in the ice and couldn't get retrieved for several months until everything thawed out.

Three building sessions to catch up on:

Last Saturday worked on getting the seat front trimmed and into place. Additional work had to be done to get it's doubler into place and drill the holes for the controls. I also trimmed the fuselage longerons and doubler to be even with the skin. This took about three hours.

Last Saturday I spent lots of time futzing with the forward fuselage side and door sills. We also took inventory of the controls and landing gear kits. One the nose strut was in my hands, then I went to work on the upper and lower bearings. I found that the holes in all the parts the strut was supposed to fit through were too tight and small. My guess is that the strut was a smidge to large. In any event all those holes has to be opened up a tiny bit. Then the upper bearing got drilled into place. We spent about 4 hours total.

Sunday I spent about three hours working. I spent most of the time fabricating the gear stop plates ( 7F8-6 ) and the other half of the lower gear bearing ( 7F8-5 ). The rear lower bearing had some problems ( 7F8-4 ). First the hole needed to be widened. Next the bend was slightly off. On one side the radius was 10mm from the pre-drilled holes. On the other it was about 7mm. This wasn't too big a deal since the hole needed to be opened up anyway. It also confuses me that Zenith would make a complicated part like 7F8-4, but not a similar and simpler part like 7F8-5.

Tuesday I received the controls subkit, but I have not yet taken inventory. Instead I worked for three hours on the floor skins. The floor skins are drilled together along with the channel that the main gear suspension sits in.

To get around having to use an angle drill on the channel doublers I pre-drilled the doubler plates, then drilled them into the channel on the outside. Since I was careful about drilling straight into the metal I was able to then cleco them inside the channel in their proper position.

I accidentally pre-drilled the aft floor skin ( 7F8-8 ) without realizing the best way was to pre-drill the channel ( 7F10-1 ). Since the channel sits on top of the skin, I was looking at a situation where the skin would have to ride up the radius to drill into the correct position. Instead I was able to keep everything aligned and just flipped over the skins and channel. This way I was able to use the web to verify the correct position of the skin. Using a square and my 48" level I was able to verify that everything was centered.

The control kit should be here Tuesday. The landing gear should be here next week, and the firewall forward kit has been ordered.

Sunday, November 04, 2007

Sunday we spent about four hours working on the firewall. The piece is now ready for the engine mount and for the front nose gear.

It turns out that to work on the front half of the fuselage you need the landing gear kit. Until more parts arrive, the front gear bushings and few remaining pieces for the firewall can not be drilled into place with out the landing gear fork acting essentially as a jig.

The plan is to skip ahead where able, but progress may soon become halted without those pieces.

Three hours were spent Saturday. About an hour was spent cleaning up the rear fuselage and trimming the longerns. The other two hours were spent on the first steps of the firewall.

Due to the drill's profile and not being able to find a smaller angle converter than the one I have, I ended up predrilling the firewall upper channel from the back, clamping it into place and then drilling it into the firewall. To help keep the firewall stable and from flexing, I placed wood underneath it to raise it up and to provide an area to cleco into.

Once the side channels were into place too the entire firewall became a very heavy duty assembly.

Before drilling I laid out all the pieces into their approximate position to make sure I understood how everything went together.

Tuesday night I spent an hour finishing up the rear fuselage.

Some ("L") angle was added to the rear and the seat back was finished. Many of the holes are still A3 sized, but I do not have enough A5s for the moment and I might as well keep the metal movable until the front half is joined up.

On Sunday we spent about an hour getting the rear wing mounts into place. This was nerve racking as the distance between the wing mounts needs to be exact. Once in place the fuselage gained a huge amount of rigidity.

Monday night I spent about two hours getting the baggage floor in and drilling the seat back mostly into place. Since an extension was made for the extended baggage floor, some care had to be taken to trim the forward baggage floor to make the installation look good. Of course, the whole thing will be upholstered so it will probably never be seen anyway.

Getting the seat back drilled into place along the sides was a horrible process. The passenger side was easy, but the pilot side skin had some pucker which made drilling correctly hard.

For the passenger side I just went through the front no problem. When drilling through the seat back I used the electric drill at a very slow speed trying to find the holes.

After attempting one hole on the pilot's side that was a horrible miss, I climbed inside and back drilled the top hole into the seat back. After climbing out and clecoing that hole together, the others on the top half were easy. The bottoms holes never presented a problem since the doubler still have multiple cleco points.

Wednesday night I drilled the fuselage upright channels into place along with the upper fuselage channel. It took a little bit of finesse to get the channels trimmed at the correct angle and positioned so as to allow the gusset to lay flat AND maintain edge distance. That took about two hours.

Saturday we got the bottom fuselage uprights into place along with the upright doublers, the shoulder harness brackets and the baggage floor bottom trimmed. This took about four hours.

The doublers took some extra attention. First on the pilots side skin there was a bit of "pucker", so car had to be taken to get the doubler aligned correctly. Second, it took a few tries to get the rivet pitch correct to get the specified number of rivets into each side.

Thursday I spent about three hours riveting pieces together.

Saturday I spent another three hours. In the end the fuselage and all gussets are riveted aft of the baggage back. In addition I installed sound deadening material on the aft side of the baggage back, and on the top diagonal area on the side skin immediately aft of the baggage back.

It turns out that leaving the forward longerons pre-drilled at A3 is a good idea. I fit the fuselage gussets and found that I needed to drill through existing A5 holes.

The shoulder harnesses are rounded and ready to be drilled. I also have the forward fuselage channel clamped into place.

It took two hours to finish assembling the fuselage. I tried to pay attention to the route of extraction so all the clecos could be easily accessed.... but the baggage area's clecos are hard to reach.

I did a quick count and calculation. Currently there are about 446 A4 clecos being used on the fuselage right now.

In addition, all the ("L") angles that attach to the bottom skin are now riveted along with the doubler for the controls on the top skin.

Two hours were spent Sunday finishing the priming job. A while ago I ordered what I thought was the last of Wick's Zinc Chromate, but I ended up receiving the new Tempo primer that is "chromate free".

Most of the fuselage has been primed with this now. There are several issues with it. First it seems to chip off in clumps easier. Second, the initial spray is mostly propellant until a good 1/4 of the can has been used. Third the spray button is much harder to press and hurt my finger after a while. Fourth, and most importantly, the primer smeared or erased my Sharpie marks severely.

It only took about an hour Monday to get the "frame" reassembled.

I did a few steps to ease the reassembly of the fuselage. First with the ("L") angle that meets with the gussets, I scribbled the backs with different colored Sharpies so it could be easily determined where the overlaps happened and in which order.

Second, I numbered each set of of holes on the gusset so I could maintain orientation. Luckily using multiple methods worked since many times both were erased by the primer.

Wednesday I deburred and chromated for about an hour and a half.

Friday the remaining skins and angles were deburred. In addition much of the bottom skin was riveted. I decided it was best to rivet the bottom skin separately so the fuselage would not have to be rotated onto it's side. This also freed up several hundred A4 clecos. This took about two and a half hours.

One major tactic I'm using is to try to keep sub assemblies together to make reassembly easier. So far it's working.

Two hours were spent on disassembly and deburring. The top longerons, sound reduction ("L") angles, bulkheads, rear most truss, top skin, and baggage back were all processed. In addition I cut the baggage area sound deadening material.

As an experiment I took some extra 3/4" sound proofing material and roughly cut it to the size and shape of my Jeep's floor mats. I've noticed that much of the noise in my very loud Jeep seem to come up through the floor. You can feel it in your shoes. While I don't have a sound meter, this should be an interesting test... even though the frequencies will be completely different, I didn't open up the doors, or the firewall, or do the rear passenger area.

Six hours were spent changing the color of the clecos. Everything is now at least an A4, with most A5s drilled. There are still a few A5s, but finding were they should go will take the longest time.

Some of the sound proofing material was also cut.

On Friday I ordered my upholstery from Skyshops. During the two months it takes to get here, I'll just use some sofa cushions when making airplane noises. When ordering the fabric I made a color swatch and a mockup based on Brian's ( http://www.701Builder.com ) interior.

On Saturday we spent about three hours. Most of the time was spent changing the color of the clecos.

The major progress made was with the additional ("L") angle placed on the side skins. To get them on was a two person job. One person was on the inside cutting and trimming the pieces to length and buttressing the piece while it was being drilled, while another was on the outside spotting for the edge distance line, drilling and clecoing.

If I were doing this again, the simplest way would be to predrill the holes and add the angle before mating the skins together.

Because of the space restrictions, being unnecessary and better fit, I did not tie the angle into the other frame pieces.

When the forward most piece was added, there was some noise reduction when the fuselage was shaken. When the aft most piece was added there was a huge reduction. Now the only shaking noise comes from the forward pieces that have not been drilled yet.

Thursday I got in two hours of work. We got the baggage panel drilled into place, along with the uprights getting tied into the ("L") angles they are adjacent to AND I predrilled the side skins for the extra stiffeners.

Also pictured today is my fix for the overzealous trimming I performed yesterday.

With this baggage panel in place the rigidity of the whole assembly seems to have doubled.

It took two hours to do a thirty minute job.

I accidentally way over trimmed the extended baggage panel ( 7F8-9B ). And by over trim, I mean I read the plans and the the directions...

The plans simply say "trim to fit", but I forgot that the panel was supposed to overlap the Zee Channel ( 7F8-10B ), so I thought the panel was 10mm too long, which made since since the baggage back was off by 10mm.

The remedy the situation I was able to find some extra 0.025 laing around that happened to be 800mm wide. I cut a piece 60mm deep and drilled it onto the front of the panel. Problem solved.

I did have to trim the extended panel in by 5mm on each side.

That will teach me for not triple checking against the HBH videos, plans AND manual.

The only building on Saturday was that of a doughnut cutter out of scrap. The subsequent homebuilt pastries were superior to anything Dunkin or Crispy could produce.

One Sunday we spent about three hours on the fuselage. I discovered that the mounts on the horizontal stabilizer are about 10mm to far inboard on each side, so they have to be opened up again and fixed.

The uprights, ("Z") channel, baggage back, and lots of ("L") angle were all drilled into the fuselage. The whole assembly is now very stiff.

When positioning the ("Z") angle it was helpful to use some scrap as a gusset - just clamped on for the moment to keep the piece in the correct vertical placement. Also the angle had to be trimmed on the sides for it to fit correctly.

During this process a second set of hands has been required for the effort. It's really unclear to me how a person could do most of this alone.

Saturday five hours were spent. The big highlight was the mis-matched ("L") angle. I'm still trying to decide what to do about that. Besides that, the rear hole doubler was put in place, the sides and top skins were mated and the bulk heads were drilled into place on the pilot side and top.

The fuselage is squared up.

On Saturday two hours were spent once again on the CNC error, and getting the interior gussets into place. The gussets still need to be trimmed.

Also, I am considering adding some extra ("L") angle to reduce the "audio slip indicator":

Recap of the question posed to the Matronic's Zenith list:

I'm having a bit of a problem. The ("L") angle that attaches to the top of the baggage back is off by exactly 10mm. This seems strange since every other junction is dead on, and the longeron splices are exactly even between the sides and the top. The flanges for the bulkheads were dead on.

So this leads me to believe it is a CNC error, but it's a little hard to get up there to measure and prove it.

Anyway, this has produced a gap too big to shim and I'm not sure what to do about it. One thought I had was to move the angle forward, but then the existing holes would be directly over the baggage back and the vertical ("L") angles.

My other idea was to ignore the gap basically since when I test fit the baggage back only the area near the gap didn't site flush. So I would add some extra rivets towards the inside of the panel to make up for it, and maybe add two gussets. My guess is that two rivets on each side would have to be skipped.

Saturday we spent about two hours mating the passenger side skin to the bottom skin. To do this we also drilled the top side longerons to the top skin. Also the bulk heads were drilled to the passenger side.

This is all insanely cleco intensive.

Seven hours of progress were made on Sunday. The bottom skins, longerons, "L" angles, "Z" angles and bulkheads were drilled out to A4 and A5 holes. The everything was deburred and corrosion protected then reassembled.

The "L" angles for the top skin were drilled into place and trimmed, and the longerons were lined up and are ready to be drilled.

Everything was simple and straight forward, but the number of holes in the fuselage takes a hug amount of time.

We spent about three hours on Saturday night. First the upper longerons were drilled to the pilot side skin, then the bottom longerons were transfered to the side skins. After that the torque tube bearing and doubler were deburred, zinced and riveted together.

When transferring the longerons, the best thing to do is to use a helper and hold the bottom skin next the to side skin to help accurately determine the position of the longeron on the side skin. In addition, use a Sharpie to mark the edge of the skin against the longerons and the position of the bulkhead rivet lines for additional accuracy.

A fellow EAA chapter member gave me a generous ride down to Portland in his RV-7A. That is a nice flying plane. The control was so nice I believe I need to fly down to Oregon again to get a factory ride in the RV-8... because it's never too soon to think about the next project.

We spent about two hours working on the passenger side fuselage skin. A good portion of that time was spent determining which of the pre-drilled hole lines the "L" angle was to be attached to. I found that placing a piece of wood between the "L" angle and table helped keep the pieces lined up.

Besides that, the sheer number of holes for the longerons takes a while to drill.

It turns out that determining if a skin is in the radius of an "L" angle or longeron is hard. To help keep the skin out of the radius of the longeron I used a red Sharpie to draw a line down the radius of the longeron. This visually made the process much easier.

It took about 3 hours to complete section two.

A good portion of that time was spent testing the flat drill bit on scrap to make sure it would work on aluminum with a hand drill.

There were also two mysteries not solved by the plans or the HBH video. First the (Z) angle that runs alongside the access hole was about 680mm. The (L) angle perpendicular to it was about 180mm. The edges will have to be trimmed on all four pieces to an angle to match the pieces around them. Also round off the edges.

I also found that 7F6-1 ( Bottom Channel ) had the be trimmed by several millimeters on each side and the flanges trimmed to an angle to fit even though it was in the correct position.

Unclecoing the front of the bottom skin and then pulling it over works well for drilling 7F6-1 into place, but the entire assembly will have to be flipped over to install the (Z) angles and (L) angles.

It is also important to note that Zenith does not supply hardware to attach the access cover with. They do give you the option of riveting the panel to the skin.... but that's not really an option. Buy some nutplates before reaching Section Two.

The first part of Saturday was spent dealing with the empty crate. After unscrewing and prying the thing apart we got our driveway back.

In three hours the entire first section of the fuselage manual was completed. The rear bulkheads, (L) angle, (Z) angle, and longerons were all drilled into place.

Much of this quick progress is attributable to having seen the steps performed first on the Homebuilt Help videos.

Bending the fuselage skin forward to get to the bulkhead flanges is a great idea. To help with positioning the longerons, I backdrilled into the table through the bulkheads and (L) angle to allow the bottom skin to lay flat to the table while clecoed together. This technique also help keep the longerons in place while drilling and the skin from creeping into the radius of the longerons.

A lesson from having my wings inspected:

One thing to look for: With the skeleton assembly of the rear strut support, make sure that the piece of (l) angle that helps connect the trailing edge skin does not interfere with the middle line of rivets.

This is the best picture of the issue I have:



The rivets need to be drilled out and the area near the rivets needs to be filed into a a circular shape so the metal does not rub against and cut the rivets.

The other thing to look out for is the fit of the root skin. You do not want a perfect fit between the wing and root skins. They will shift and rub against each other in flight and is a potential source of cracking. Make sure you have a gap between the skins and then use sealer later.

After a big struggle with Sunshine Shipping the initial 9AM to Noon delivery window turned into 9:15PM.

Saturday morning I had my wings inspected by an A&P/701 flyer. There were a few corrections to be done, but nothing painful, tricky or too time consuming. My plan is to perform these later closer to final assembly.

Saturday evening I took inventory of the fuselage crate and found a part to be missing. Luckily it is a part used later on in the process.

I bought the Homebuilt Help 701 Fuselage DVDs and started watching the "Rear Fuselage" disc. Overall this is a big help, but it could have slightly better production values. I fully expect that just seeing the steps performed will have major time off the fuselage.

Two hours were spent on the last holes on the right wing. Many holes still need to get drilled out to A4 and A5, but the hard part is done.

For the inboard section of the wing root I made only a few holes with the strap duplicator making sure that the top skin had the crimped regions marked. Then I connected the dots and drilled the remaining holes for a better fit.

The extra 400 clecos ordered from Wicks came in handy.

On Saturday my wings will be inspected for craftsmanship, and any needed corrections will be made. After that I will do all the needed drilling out, fuel filter installation, ground wire installation, deburring and corrosion protection, final wire run and then riveting. I hope to get back 500 clecos from the wings.

Friday the fuselage arrives at some point between 9am and Noon.

We spend four hours on the right wing. The fiberglass and metal Horner tip were drilled into place along with the outboard portion of the wing root skin.

For the (L) angle that helps holds the tip, the best thing to do is to predrill the portion that contacts the spar extension, and then back drill it into place. Otherwise it would be to awkward to get the drill into that portion of the wing.

The fiberglass fit much better this time, but I had to fabricate a small extension to get the nose skin into a safe edge distance on the most rounded part of the tip.

The area of overlap between the fiberglass was much better and no extension was needed this time.

When you layout the wing root skin, do yourself a favor and actually use the corner of the metal as your ( 0, 0 ) point.

This time when doing the rough trim I was smart enough to use the Olfa knife which saved a huge amount of time.

Over the weekend only a little building got done due to camping, and then a light cold.


First last week, there was one hour of building that included drilling some holes out to A4s and getting the lower tip angle positioned, but not drilled.

The skin had a slight bubble to it that just got pushed around. The solution was to drill out the rivets holding the outer most lower skin to the trailing edge skin, drilling the lower angle into place, and then enlarging the previous holes to A5s. This did not eliminate, but drastically reduced the bubble.

Monday nights session was only two hours and included drilling the top and lower angles into place and preliminary positioning of the fiberglass tip.

It was a two hour long battle to get the fuel send perfectly seated into the tank.

Several issues to avoid
  1. Zenith shipped an extra seal, the one I used was a worse fit than the other.
  2. The ohm meter had a calibration wheel that I forgot about, and I was confused to why the readings were so strange
  3. Make sure that hole is circular! If not you may need to smooth it out to keep the bolt from using the tank as it's thread.
Most of all, enlarging the hole is a slow process. I also got the grounding setup on the tank,

Sunday we spent five hours in a building sprint. The lessons learned from the left wing allowed for rapid progress on the right wing.

The first, smaller cut for the fuel sender was made, the fuel tank channels were drilled into place, the fuel drain hole was made, and the fuel feed hole was also made.

For the fuel drain hole I attempted something different. On the left wing I measured and was off. For this wing I place the tank in the wing and felt where the drain pushed against the wing, and marked that spot.... and was off. So I measure and hit it on the spot, creating two holes. I created a patch that rested on the inside to close the hole up.

The fuel sender hole is just a rough cut and needs to be enlarged.

Luckily the fuel filler template was 100% reusable for this wing. Due to the CNC pre-drilled holes, I was able to just flip the template over. I undercut the hole intentionally and then enlarged the hole with a half round file for a near perfect fit.

For comparison the same amount of work for the left wing took about twelve hours.

We spent about three hours on the wings Saturday night. Only one hour was spent on construction. The other two hours were spent on the workshop.

First up was bending the wing root skin and drilling it. This is harder than it should be.

First I bent the trailing edge as indicated in the manual, but the skin is too stiff. I attempted using duct tape to hold the skin, but that didn't work.
After un-clecoing the skin, I made a few slight bends in the skin to make it easier to round the tip ribs. Then using an assistant, the holes were drilled.

The left wing is now ready to be inspected and prepared for final riveting!
