Hide glue use

<< < (2/3) > >>

DC:
I'm also a little confused by this statement "First, 10-15% glue (the type that gels well)" from Adam's book. I made some 10% glue from my best glue. At 35% this stuff gels very quickly. At 10% it has to get pretty cool to gel(or at least so I can see it gel)  Is he meaning 10% glue that gels well or is he meaning a 10% glue made from the stuff that normally(35%) gels well?

I've found that once the glue is dry no reasonable amount of heat will liquefy it. It just gets drier. If the glue is just gelled then it will liquefy. I've been checking the temp of things and the glue gels at about 70°f ish so when everything in the shop is 75° it gets kind of slow. What do people do in Arizona? I keep wondering if I should be making a better batch of glue. Have you ever seen a site that ranks hide glue by gel temp.

 Don,
         I seen some info a while back on violin making but that was a deep rabbit hole I went down online...If I find it again I will send it to you...It was more about ratio

Hawkdancer:
There might be a luthier in your area who can provide some gluing advise.

     Humidity is a big factor in gel time...Before laying sinew I will turn my AC off here in SC...It gives me more working time in high humidity...

DC:
It's about 60%RH here now.
