Bill, the baby bottle warmer is shown in the video in post #6. He used baby food jars for the hide glue and caps and refrigerates them after use.
As I am gaining more experience with hide glue on the 2nd planking of my build, I am finding I prefer it over either CA or PVA glues. I thought the requirement for heating it prior to using it would be a mental obstacle but it doesn't bother me at all. The glue pot and heater I purchased make this part of preparation very easy.
I also appreciate how quickly it sets up, yet not so quickly that you have to work fast though. It's also nice there are no concerns about getting it on your fingers, just wash it off with water. I have used finger pressure on places difficult to clamp or pin and held it in place until the glue set. Try this with CA and your fingers are one with the planking. Try this with PVA and your fingers will cramp before the glue sets.
I have inserted sliver-sized spiles by dipping them in the glue pot and sliding them in place. The glue leaves no traces like CA or PVA might by darkening the wood and sealing it. And, if I understand this correctly, there are no worries about hide glue being left on the surface when it comes to applying dyes, stains or finishes. So far, I'm pretty happy I made the plunge.
