This works but it takes a long while for the lube to melt. The lube can is too small. You should use a larger can like a tuna can with a snap on plastic cover.
This thing really works. It's efficient and helpful. Can't ask for more than that.
I haven't used this cup holder and the lube yet but it looks like a great system for looming black powder paper cartridges. I can't wait to get some lead balls cast, so I can try it out.
