I've got an idea for something I plan to test out this weekend to see if it will work for spinning spools to mount to a drill. If it works I will report back. I was looking at some 3 jaw self centering chucks like you'd use for a lathe and those are nice but you'd still need to modify it to get it to work with a drill. I hope my idea works out, if so it is like 5 bucks in material and a little bit of time.
