Bill
Thanks for posting. As a one time builder of one of his planes I had nothing but
praise for him. Sad in deed.

I absolutely would not just buy a reamer the size you think you need or the
size the bolt calls for. You need to measure the pre existing hole in the
spar and use that size reamer. If you take it for granted the hole that is
there is the proper size and it is bigger you have just reamed the new
doublers smaller than the spar cap holes and guess what you have just done? I
will be using oversized NAS bolts and will use the proper size reamer to
ream for final size. I don't want all the stress only being taken up by the
new doublers and the cap holes being sloppy.
Just my 2 cents
Jeff

Hey Jeff
That sounds like a totally logical and sensible idea.
With the centre spar out of the aircraft it would seem easy to join the
centre spar to the wing spar with the old 5/16 bolts then "match"ream each
hole to final size (3/8")
Do you know what oversized NAS bolt are required? I find the nomeculature of
NAS bolts impossible to understand!!
