Fit/Temporarily Installed Right Gear Weldment
Today I started fitting the gear leg weldments. These things are a bear to get in there. I had to trim back the lower longeron a little and remove the outboard-most platenut on the spar box flange, but I got'em in. Also note that spacer that's between the two 704 halves.
And this piece gets two flush-head screws from the outside. The only problem is is that this piece is pre-punched...but one of the holes is directly behind this bulkhead, so you can't reach it directly and it's too tight in there to get my angle drill.
So what I did is use my 12 inch #40 bit and drilled through the bulkhead and into the pre-punched hole all the way to the outside of the fuselage. Then from the outside I enlarged the hole to #12. Also notice the spacer between the weldment and the plate there. This is just a scrap piece in here that will get shaped to the size of the plate on the weldment. Van's gives you the option of using spacers here or pulling the weldment out and rebending it...uuhhh...spacers it is.
These bolts (one missing here) go into the welment. The -7 gets regular rivets here since there's no weldment, but the -7A gets these AN3's.
And here are two bolts in the holes where the flush screws will go. The plans have you countersink through the skin to get to the longeron, which is a fairly unconventional way of doing it.
Next I tried installing the left weldment. I finally gave up after about an hour and a half or so. Something is definately not making sense. I'll put it in and the holes just aren't lining up with the spar box holes. I think the long weldment that attaches to the lower longeron is a little to far 'outboard' so I'll have to bend it back in...which is no fun but doable.
