I'm about to have a set of false spars machined and before I have metal cut I thought I'd see if anyone else has a known good design that they'd like to share.
I'm planning to use "free fit" holes - my drill chart calls for 15/32 (=0.4687") for the big holes and 0.266" for the little ones.
The hole spacing is harder - I tried to measure my spar and it seems like Vans arranged the holes such that there is a constant amount of material (about 0.445") left between each.
If I work the numbers right (a big IF...), starting with one of the small holes, I get hole locations of:
Small hole: (0,0)
Big hole: (0.812,0)
Big hole: (1.726,0)
Small hole: (2.538,0)
Is this similar to what anyone else has done?
Thanks for any info,
