What size is .290?

Post by PoconoJohn »

These incredibly superb, outstanding plans show FSBW2 (sheet 6) has some holes (not sure which ones) that are .290 (odd size). I have no idea what bolts I would use; sheet 7 is no help. I'm going bald fast. Been stuck on this since May 22. I'm starting to think that if I'm ever going to get this done, I'll have to consider the plans as only ideas/suggestions to get me in the ballpark. In this case, I'm going to go with .3125 in all the holes except that one that's .250, close enough.

Hi John,
I checked back on my drawings and found a big question mark penciled in too. I drilled and reamed them to .3125 except for the one at .250.
