There is a very thin fine line in making this stuff work. I've been through needle switches before finally settling on doll needles, very long, thin things. I don't have the foot switch, and have realized if you go too fast the needle will turn into a sythe destroying anything in it's path. If you use a plug thing with a drill bit in the middle it won't work on the Dremel. ONce you get through the production part it really comes together quite well. There is a very fine line between success and a trip to ER. JGW
