Hi all,
I am installing my control surfaces and have solid circular CA hinges. I read a few posts on CA installs and am confused about the slot drilling. Should I drill a 3/32 hole in the trailing edge of the wing, in the middle of the slot where the hinge will go or somewhere else? Any help would be appreciated, Thanks.
3/32” (.093) is a bigger hole than I would make. The CA hinge is only .012 to .015” thick so a hole 1/16”(.062) is all you realy need.
Mike, That's a very good link. Most of the time the push pins serves as a good gap spacer too.
I like to put my reading glasses on and watch the wicking action as I add CA. Depending on how porous the wood is, usually at 4 drops it slows and this is the time to stop because a bead or fillet of CA at the joint can make the hinge brittle. I keep a corner of paper towel handy to QUIKLY dab out the excess. This is rarely needed.
