Holmegaard build along
Markus:
Wow that is a goodlooking piece. Markus.
Canuck Archer:
I notice that you use TB3 and you use rubber bands to fasten the backing on. I use TB3 on my backed bows, and I use clamps, and works fine, but it's time consuming and takes a lot of clamps. I clamp every 2 inches so I have 36 clamps at times. I didn't think that TB3 would harden without oxygen, and with rubber bands I don't think it would get air in order to dry. But if it will dry ok with rubber bands, then I'll switch. BTW I live in eastern Ontario, Canada, and gets pretty cold here too. Thanks for doing the build a long.

I've been using bicycle tire inner tubes for clamping for years now, with no issues. It actually works better than clamps, and is much cheaper. I leave them wrapped overnight, and have never had a problem.

whether your using clamps or inner tube or ubber bands
you are doing the same thing wen they are applied
you are squeezing all the oxygen out of the glue joint
most adhesives are anaerobic
which means they set up with the lack of oxyegen present ;)

It's not so much oxygen that's needed, but rather the circulation of air so the glue will dry.
