Homemade Hot Hide Glue Brush

I’ve become something of a hide glue junky. It started with liquid hide glue. I was intrigued with the chemistry of adding urea to hide glue and water, following the cooking method and emerging with a glue that’s strong, liquid at room temperature, and probably the easiest to work with that I know of.

Liquid hide glue has some great characteristics, but lately I ventured into hot hide glue. I’ll leave the nuances of liquid versus hot to the experts like shipwright, but one thing you definitely need with hot glue is a good brush to keep in the pot. The French brushes are 10 to 15 dollars, and from what I understand, the usual acid flux brushes aren’t a good choice because the metal can react and cause discoloration.

So…. I started with this blogger's idea. I took a chip brush from Harbor Freight, stripped it and wrapped the pieces around a dowel that I shaped like shown in his blog.

Doing it this way leaves the ends of the brush a bit uneven, but by soaking it in glue and letting that harden for a day, I was able to shape the bristles on the belt sander.

The result is below, but I want to be sure to give credit to Greg Merritt at https://hillbillydaiku.com for the original idea of using cheap chip brush bristles.

Looks like a winner Rich and good ones are hard to find in stores.
They are however out there. I use these and really like them. They last a long time too.

These work well too and are really cheap. I still use them because the small sizes are great for getting glue into small places.

There is still a satisfaction in making your own.
Well done.

Rich,

Are you doing any veneer work with the hot hide glue? I am considering a veneering project. I have ordered a couple of books, but veneering is a stranger to me.

RL, shipwright is the man to talk to about hot hide glue veneering. The only veneering I’ve done is with plastic resin glue.
