Title: landing gear blocks, wing sheeting? Easiest way?
Post by: dave siegler on January 21, 2021, 06:57:28 AM

So one of the things I have struggled with is the bottom wing sheeting and cutting around the landing landing gear blocks. 

The blocks are glued in and are about 1/16 proud of the wing. 

How do you deal with it and make it accurate?  Over the plans? multiple small pieces?  or trim and fit?

 I simply measure and transfer those numbers over to the balsa sheeting. I guess you could lay down paper in place of the sheeting, mark the paper, cut it out and lay that over your sheeting. ...gene

I use Bob Hunt's method. He's posted a great overview here:

Although Bob's post mainly focuses on foam wing installation, his approach to built up wings is similar.

I set the blocks with 4 2-56 blind nuts even with the plywood half ribs and sheet over them.  Then I cut out a 1/8" smaller section than the block and replace it with a 1/32 plywood covered by a 1/32 balsa cap cover plate held by 4 small bolts with tapered heads.  That way my gear mount doesn't become a VG where I don't want it.
