I've been looking at glue pots. Most are just double boiler setups with a jam jar or such for the glue. It seems to me that trying to dip a bundle of sinew into a jam jar would get old real quick. Do you guys use a wider, flatter container of some sort and if so how do you control the evaporation and temp?
-
I use a double pan set up on a hot plate. Plenty of room for sinew bundles
-
I use a Cool Whip container floated/suspended by a piece of wire in a soup kettle of hot water... wire wrapped onto the kettle handles. Sinew bundles dunk easily, and afterwards, after the glue solidifies, I put the lid on the container, and put it in the freezer until next time.

I float my "pot" in a rival hot pot express -- $3 at the thrift store
-
I bought a cheap crock pot at a thrift store and put water in it and floated a SS bowl in it with the glue in it. If the glue seems to get too hot just add a little cold water to the glue or even to the water in the crock pot. This worked better than any other method I've used.

I use a double boiler set up, just a small pot with a ceramic bowl on top.
I always use my digi thermometer to make sure the glue doesn't get too hot.
Once water is boiling, I turn it to simmer and the temp stays good for a while.
I've heard of ppl using a rice cooker on the warm setting
-
So, by the sounds of it you all use a shallow dish for the glue. Any issues with the glue thickening too quickly? I guess you just have to deal with it if it does :D
-
I use a decent sized bowl, around 8" diam? I prefer a bigger bowl and a good amount of glue in my pot. It freezes and melts nice and easy.
What are you sinewing Don?

Any issues with the glue thickening too quickly?
in the pot or on the work?
I find if you have a primary unit with an adjustable thermostat, you can minimize getting the glue to hot, but if you dial it down too far, you don't have much working time with the sinew. keeping the wood warm really helps make things go well.
-
In the pot. This will be my first sinew job(if I do it) so I'm just trying to cover all the bases I can.

I got a v small deep fat fryer which I spot calibrated at 70 degrees C works a treat :)

I guess the lower the temp in the pot, the slower it thickens. its not much trouble to thin a little, but getting it too hot might weaken the glue from what I read.
I get the threads applied and where you want them, and do not worry too much about extra glue or loose ends, even if the glue is gelling too fast.
once the threads and wood are together, you can easily warm the whole assembly till the glue un-gels and apply finger pressure to smooth out the surface and wring off excess glue. hide glue is different, and easy to play with by changing temps.
Practice with string and an old board to develop a technique.
-
If the hide glue begins to thicken I just add a little more warm water.
Keep a bowl of warm water near by and a damp towel so you can clean the glue off of your hands while you work.
-
Don are you making sinew glue or wanting to use sinew glue?

Wanting to use. I've made quite a bit.
-
here is my favorite way......I just move the switch back and forth from high to low to keep the temp of the water at about 160 I figure the glue is a little less....if it thickens some from evaporation I add a little water.....

My set up is similar to DBar's.
