Thanks for the posts bownarra. Filtering the glue is a good idea, it's probably gotten a little mungy. It went on real nice and glossy, it just had a few nibs. How long do you let it dry before you unclamp it? I need the clamps for the other side but I may buy some today.

I used the rope and waited couple of days ... just to be sure  (-P

More questions. in the book Adam says to use very hot glue. Everything I've read says the optimum temperature for hide glue is 140°f. Is that what he means by very hot?

bownarra:
Yes that is correct. It will start to degrade  once you hit 65 - 70 Celsius. I judge the temperature with my fingers now I have the feel for it. A simple test without a thermomenter is to get a very fine piece of sinew and dip it in the glue. Too hot and it will shrivel up.
I also leave it a couple of days to be sure. I once had a strip with matching grooves misalign when clamping. The first clamps were only on long enough for it to gel.....you wouldn't believe how hard it was to get off even after that short a time. I would think that one day is plenty but....

DC:
Thanks. One more thing cleared up :D
