More F-705 Work
Today after work I started drilling out the F-705 stuff. It's a bit tricky, since there's a spacer that goes between the spar and the spar doubler. You have to keep that thing from spinning. What I did was take a scap piece of the bar used to fabricate the spacer and I put it at the outter edge between the spacer and the spar (you can't see the scrap here...it's sort of hidden by the C-clamp). The c-clamp is pulling down between the two pieces and it pretty much keeps everything stationary. Worked very well for me.
Ok, so I should have rotated this photo....whatever. You can see here that the spar got match-drilled.
Next was these seat-belt brackets. These things are for the lap belts. The plans have you drill the left ones and then clamp the right one on with a shim that keeps them the appropriate distance apart.
Instead of making shims, I just used AN3 bolts, which just happen to be the correct diameter called out for the in plans. This picture was taken before the final fitting here, you can see the bracket on the left is a little off..but I got it straight when it was drilled. I really don't think it's absolutely super-critical that you get these things perfectly aligned anyway...but I got 'em all pretty close.
Wow...it doesn't seem like I got a whole lot done today but I spent a while out in the garage. One step at a time...
