I have the same problem. Maybe its from being used to holding the gas pedal to the floor, or maybe I'm to slow. I have a Mittler bead roller. I bought a HF router speed controller but have not had time to try it out to see if it will do what i want it to. Steve
let me know how it works. i have watched people on utube and there roller is moving real slow, maybe i need more time rolling
Sewing machines - pinch your wife's one (if she has a sewing machine) and see how it goes. Thats what all the sewing machine co's use and the drain through the circuits is not that bad. If there is not one lying around ask at a craft shop for an o0ld sewing macine and pinch the foot control off one of those
Try these, made for pottery wheels pipe rollers and such. http://www.ssccontrols.com/homepage-potentiometercontrols.htm
Lots of switches, even if only typically used on 120, are rated for 220. Might need to look at the actual switch itself. I'd start with sewing machines, people give away whole units.
Sewing machine switches likely only have one switch and you would need two of the linked together to be able to control both legs of 220.
Industrial sewing machines have a clutch and brake. Those crappy home sewers have variable speed controllers. Also look at some Bosch "industrial" hand drills for their variable speed trigger
I got one of these, from eBay.http://www.ebay.com.au/itm/Variable...038&pid=100011&prg=1005&rk=1&sd=110735780424&
