Atco Glue Pot or Cement Keeper Brushes

[mbnaegle]

I have 3 of the old Atco Cement Keepers and want to get new brushes in a couple. I've heard that Atco is no longer making them, or at least not here in the states, and the new ones that are available (from various suppliers) have a different screw thread holding the brush onto the wand, and consequently the new replacement brushes are also a different thread. Has any one else had an issue finding brushes to fit their old cement pots, or is it a matter of who you buy them from, who has old stock, etc.? They're not expensive, but I wanted to ask before I have to make modifications to make stuff fit.

I had one pot that was missing the top cone/wand, and I copied an existing one to make a replacement on the lathe (not a prudent thing. Just want to keep Dad's old tools kicking around), and when I did I found that the threads were 1/4-28. None of the sources I've seen list the thread size, but I've seen some pictures of replacement brushes that looked like they had a course thread, like a 1/4-20.
