Final followup to this issue. After a full week the glue is fully cured now. I would not have had to remake the brace. I am not upset as I need the practice. Also, using my new high-precision scale on the glue resulted in it curing in the normal stated time for 206 hardener. In the past it always took longer than that for my epoxy glue ups. My old scale was not accurate at lower weights and I’m glad it’s gone.
So much to learn, it never stops, eh?

I took the brace off bit by bit. The glue was not hard and peeled up in some spots. That was the right way to go for this goof. I have plenty of spruce to make many more braces and I hope it’s only one more for this project.

I use pumps and measure by weight in grams. I think what happened is that my cheap digital scale was not giving me accurate values when I was making small amounts. I’ve used this method and scale many times with success and this was the first failure. I have just received a new scale that is accurate to 0.1g so I’m hoping this doesn’t happen again.
I am thinking that you are right and I should take this brace off and remake it. This is a learning instrument rebuild and I can chalk this up to learning a lot this time. Painful but valuable. Sigh…

Thank you for the reply.
I’m using 105 resin and 206 hardener. This is not really a repair. The guitar was fully apart and I was able to salvage only the plates and sides. It’s more like a kit with pre-carved plates and pre-bent sides.
