I just posted my English wheel build in the tool section.

I have used several different motors in my minis. Anything from a 6.5 horse OHV Honda clone motor, to 3 and 5 horse Briggs & Stratton motors. Basically, industrial motors. You can generally find 3 horse B&S on industrial edger trimmers, and small rototillers. Check Craigslist, or buy one new. I also have a 14 HP Briggs V-Twin in store for a later project.
