First, to anyone who is about to order their wheels please, please, please pay attention. Just spend the extra $30 a wheel and buy the tubes. The Matco tubeless tires are a nightmare. Seriously, I would rather rivet my hand to a rabid raccoon than deal with those things again.
I probably spent 15 hours trying to get them to inflate.
Some of that time was spent trying to separate the wheels. They can be really tight a large amounts of brute force will need to be applied.
The valve stems are a pain to install. A local tire shop was kind and let me borrow a valve stem installer. After that you need to get the wheel somehow beaded with the tire AND then slip a crazy rubber band gasket on between the two halves of the wheel.
If you use the tubes then the valve just slips on through and the wheels self bead.
A huge amount of progress was made thanks to the help of another local 701 builder. Together we made substantial progress on the slats. The slats are pretty straight forward, except for a few gotchas that got me. The biggest has to do with the "L" angle that reinforces the slat skin near the supports.
Trying to be industrious I went and cut the "L", notched it, bent it to match and then located the holes and drilled them into one piece. I used one of the ribs to back drill into a mirrored rib and then duplicated the holes to all the ribs.
What I forgot to do was check that all the holes of the "L" went into the support. Luckily all the holes that made it into the support were within minimum edge distances, but one hole missed. So I had to drill a fifth hole into the "L" that then made it into the slat support.
In one monster eight hour session we got the "L" spar drilled into all four slat skins, all the ribs, supports and "L"s riveted together and on one piece the ribs drilled into the skin.

Quick status update:
The doors are on, the latches installed, the hinges hinging.
The main gear have had their notches made and are test fit. The front fork is ready for the wheel and tire. The landing gear and strut fittings have finally been bolted into place.
I did have some problems with the Matco wheels. Despite following the drawing, I can not separate the front wheel halves. There does not seem to be a retainer clip or anything like it.

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.

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.
