This is another "new to me" material I've not yet tried.craft fur brushes
I use .009" stainless steel wire i get from craft a store that sells beads and costume jewelry supplies. The dremel is way too fast but I have full control and can slow it down to a crawl or stop stop it by holding onto the chuck.This is another "new to me" material I've not yet tried.
What wire do you use. (I'm assuming wire )
If the dremel is not to over powering you might be able to make a couple pulleys to reduce the speed and put a load on the motor. Wonder how a sewing machine motor would work...
That would help but I think manual counter spinning on either end would be my ultimate choice providing the spinning device has enough mass to function properly and can be spun fast and smooth with little effort.You might try putting a dimmer switch in front of the dremel.
