Interesting about the glue Beau, I thought the exact opposite about ease of clean-up. I like how the hide glue cleans up. I use a squeeze bottle to apply the glue, and a quick wipe with my finger to spread the glue on the underside of the brace. Squeeze out happens in a few places, but much of the seam is clean with no squeeze out. After the clamps are in place, and a little time has passed, a quick touch with a chisel removes the still gelling glue from where it does not belong. This is for the squeeze out, not the places where I accidently smear the glue fresh out of the bottle, that is a little more difficult to clean. If it is left to harden all the way, yes, it is more difficult to clean. I have used both the Behlens hide glue, and the stuff from LMI. I try to always clean up the PVA glues when they are 'green hard' also. I find the window of time for easy clean up a little wider for the HHG.
Before I learned about squeeze bottles with stainless nuts or similar as ballast, and as a thermal buffer, I tried a brush in a pot. I did not like that.
One of James Krenov's students once ask what he does for squeeze out. The reply was, 'what squeeze out'. I still cannot live up to that ideal, but I remember those words, I try.
