Sunday was busy even though only about 3 hours of work got done.

Dave and Pat from EAA dropped by to see what a Zenith project is all about. They are about to embark on the journey with a 601XL.

The 60mm jig worked perfectly, and I did drill the channels into place from the middle of the spar outwards, but did the middle heavy channel last. I did have to trim the rib channel position template a small amount.

Everything seems to be square.

For the middle heavy channel, we used two bookshelf brackets ( as pictured ) to keep the ribs square as the rib angle and channel were squared into place. We had to mark the holes into the rib angle and then precision drill them since clamping would have been impossible.

The left wing's rear channel should not take near as long.

Saturday we actually flew the old 150 and saw the new Olympic Sculpture Garden from the air.

Finally got a little time to work on the project. Spent about and hour playing with the rear template placement jig and the rear channels.

When I had my last major question, I was trying to determine the jig distance for the rear channel ( 380 or 400mm ). I called Zenith and Roger gave me a better way: do not even use the jig. His suggestion was ( working center outwards ) to square the ribs, place the wing channels and THEN drill the angle to the channels.

Having already jigged the long sets, I decided to do this for the short channel.

Here is the problem: I first test fitted the 600mm channels and the angle ( 7V6-3 ) was not protruding far enough from the channel. The mating surfaces were about 3-4 mm apart. The obvious fix is to trim away a small portion of the flange from the wing rib. Because the piece must be 600mm for proper rib alignment, moving the 7V6-3 or the fabricated end cap are not options.

I'm still going to follow Roger's advice for the shorter channels since I can trim the entire channel for clearance before adding the 7V6-3 and still maintain proper edge distance.

We spent about four hours fabricating the rear wing channels for the left and right wing.

The manual gives a kernel of a good instruction, but there was an easier way. If you mark the edge distance and then mark your rivet holes on the outside of the channel, you can support the piece ( placed in the jig ) during drilling with a small piece of wood underneath it. When you back drill, use the same piece of wood with a clamp to keep parts from shifting.

The first jig was set to a length of 600mm for 7V6-2SP. The manual states that for 7V6-1 the jig should be set to 380mm, BUT the length of 7V6-1 is 380mm. The plans state that the flange-to-flange distance of the completed part is 400mm, so I think the manual is in error.

The Zenith list seems to concur, but I'm going to call Mexico, MO in the morning.

Also, Robert from my EAA chapter dropped by curious to see what the Zenith build process id like compared to the RV-7 he is working on.

The amount of wood used so far to make an "all aluminum plane" has probably been enough to make a Fly Baby.

We spent about two hours cutting the false rib template and making the first rear channel jig ( both shown in the photo ). Most of that was figuring out the fancy new tool. It even can with an instructional DVD.

The router also came in handy cleaning up the workbench edge that 1) wasn't cut very straight 2) has been drilled more than Paris Hilton.

Thursday night was spent laying out the false rib template.

This was an easy task, except on the plans many of the measurements are relative to each other, making some easy parts hard.

More tools are needed... like a router to do the tight spots. Should also come in handy for the slat jig.

Saturday consisted of powertools and football. As an added bonus the Cowboys snatched defeat from the jaws of victory.

We spent 4.5 hours fabricating the skin supports for the left wing, drilling the supports, mounts and tip ribs. Everything got deburred, protected and riveted. For both wings. It was a large amount of work for very little visual payoff.

The next mini-project is the rear wing channel. This will involve some templates and a simple jig.

I spent about an hour and a half fabricating the skin supports for the ribs that also have the slat brackets.

The whole affair was straight forward, but I found it slightly difficult to drill the bend release holes. Getting a good angle to cut the L angle was also a little tricky.

Only the right side was fabricated so I could avoid any problems of mirrored parts getting mixed up.

Someone asked me if I worked on the project every night... and recently I have been. But there was a while when work prevented such progress. Even if I don't actually drill, cut, deburr or corrosion protect something, working at least every other night keeps the project in your mind and avoids having to REALLY spend some time reorienting yourself.

I spent about an hour making the slat placement template tool. The extrusion came from Home Depot and the 1/8" plate came from Ballard Sheet Metal Works. Most of the time was spent using the hacksaw on the plate. The plate is 7000 series and really hard stuff. A little extra time was spent using scotchbrite on the extrusion to obtain a nice brushed metal look. One small deviation from the plans was made: I riveted a small piece of plate between the extrusion at the end of the tool to maintain a constant gap between the extrusion and provide for better stability.

An hour and a half was spent drilling the left wing. The rear ribs, spar tip, and root ribs were all drilled into place.

Next is the slat placement template. I need to stop by the metal shop in the morning to get some aluminum plate ( t=.125, 80mm x 150mm )

We spent only an hour today, but managed to get the tip ribs drilled into place for the left wing. A friend was over helping with the build, so all the tools that are normally taken for granted become cool and new again.

The left tip ribs took about 1/4 of the time compared to the right wing, and I can only imagine how much faster the rear ribs will be.

New Years Eve: About four hours were spent on the right wing. The rear ribs were drilled into place, along with the root rib. The spar tip extension was drilled into place. The slat brackets were predrilled. We also bought a new work light and some extrusion for the slat placement template. I could not find any t=.125 plates at the Home Depot, so I bought some thinner plate that will just be layered.

Friday night we got just a little done. We deburred, corrosion protected and riveted the L angles to the left wing.

Saturday night was very productive. Not only did we drill the L angles for the right wing, corrosion protect and rivet, but also got the tip ribs drilled into place for the right wing.

The tip ribs were just a bit of a problem due to the length of the spar and our need to keep the garage door closed for warmth.

We also had a bit of confusion over which spar was the right spar and which was the left. Luckily the builder's manual and some other drawings cleared everything up.

We spent about an hour reviewing the first steps on the wing skeleton, the plans and cutting the L angle required for the spar.

Joe told me that he spent about 100 hours each on his 601XL's wings. I believe that this estimate is probably high for the 701 kit based on several assumptions. First, the flaperons are not part of the wing. This greatly reduces the complexity. Second, more parts come pre-drilled then when Joe built. Third, I believe the overall structure of the 701's wings has fewer parts.

Workbench 2.0 was finished tonight. There is a big difference in the sturdiness and look from the old workbench. Overall the height of the new bench is better ( slightly lower ).

The bench is also much flatter, as confirmed with the level ( made from 6061-T6! ).

Underneath the spars and skins can be kept safe, so we even gained additional room in the garage.

It only took two of us, an hour, a plywood plank and some cinder blocks to lift the frame onto the new base. Shimming, leveling, and attaching the table top took a few more hours.

Here is the first iteration of the old bench, followed by the second iteration:

Once again work is keeping me from the project. The workbench was a forbidding project for some reason, but we now have a plan, materials, and most of the work finished. We are going to use the wing crate as a base ( as mentioned previously ), but the question of how to add legs has been perplexing.

We finally settled on the simplest, most stable, and most ghetto idea: cinder blocks. The crate's frame rails will sit on slats which will rest on the cinder blocks, kinda like a mattress and a box spring. The only problem is lifting the crate... a problem that should be easily overcome with the help of a few people.

Using the crate has many advantages. It's better built than I could do. It already exists. It's about the right size. The wing skins and spars can be safely stored inside, yet easily retrieved. It's easy to make.

We bought 16 cinder blocks. The idea is to have four "legs" per side, with each "leg" two cinder block high. Each cinder block "leg" will have a footprint of 16"x8" and will be 6" high. .

Tuesday night we spent one hour closing the two remaining flaperon halves. Deburring, corrosion protecting and riveting are all activities I can now do in my sleep.

The fuel system and wing crate arrived on Wednesday just before Thanksgiving, and Saturday evening the inventory was done.

The fuel caps do not look like they are vented, nor do the tanks look like ten gallons capacity.

Before work on the wing can begin, the workshop needs to be redone. The table I built is not perfectly flat for it's 8 foot length AND it needs to be extended an additional four feet. My plan is to use the crate the wings came in as a workbench frame. All I need to do is raise the crate an additional two feet and provide for an adjustable shim method to keep everything level. I'm going to use the MDF from the current bench as the table top.

Surprisingly, the light at the end of the tunnel was not a train.

After a nearly month long break, work is ready to continue on the CH701. The wing and fuel tanks kits were ordered in early October and should be shipping any day now.

The slats are lamentably still untouched, but Tuesday should resolve that.
