Thanks Jordy.
Nathen, I don't think I'll need locktite Some of the holes are threaded then I'll be running a nut on them too where needed. But the only problem with 0-80 small pattern nuts is they're 1/8'' hex and the bolt is 3/32''hex and you have to keep this in mind because of wrench clearance. In one of my pictures you can see my shop made socket wrenches, the Wiha's are too thick,I turned down a socket head screw to very thin wall to be able to tighten bolts. I even design this in on the CAD so it can be assembled.And if all else fails I'm using socket head bolts,much more esier to install
I'm trying to keep very close tolerances on my hole sizes so there won't be much movement with the bolts.
"It's supposed to line up"
2mm screws aprox .078'', aren't they about the size of #1-72? I have some 1-72's installed and they're much more esier to tap than 0-80's
