it can be done with a "third hand" tool... (base with alligator clips) Or, thread a piece of rod or a bolt into the nut, then have the wife, gf, or a friend hold in place.

or you could tin the area you want to put the nut... then use a hand to hold it, instead of the solder.

Them lil alligator clips last about ............that long....I think I read something about putting a long screw into it and holding the screw with a helping hands kinna deal. I use different magnets and clamps on a pcs of 3/8plate steel anout 6x6 sitting on a bigger plate of 1/4 plate alum.

I will be getting to the point soo n in my build and am hopeing to see some other ideas from our local mcgyvers...

Home Depot sells small clamps that cost $.47 I think and have blue rubber grip on them. I got 10 to try out and see if they'll work, just havent yet.:roll:

I don't hold them, normally I'll set the area i want the nut on a flat surface (aluminum) and place the nut where I want it and braze it. You just have to be careful that the flame doesn't blow the nut around.

I like this way too, it also will keep the nut flat.

wondering this is what you use for third hand?

I don't use nuts, I weld a piece of sheet metal where i want it and drill and tap a hole. I feel it makes for a cleaner look and the sheet metal is much easier to hold in place.

I use the procedure I think Matt (mrpink) wrote up here a long while back. Essentially, I apply a bit of flux to the part of the frame I want the nut brazed to, heat it up and apply the safety silv. Then hold my nut with needle nose plies, add a bit of flux to it, press it to the safety silv, reheat and press the nut to the frame and let it cool. Generally takes me less time to braze a nut on a frame then it did for me to write this!

I've successfully used this technique for nuts as small as M2's, but usually am brazing on M3 nuts.
