DIYbanter - View Single Post - 5 hp 3 phase motor to a 3/4 hp single phase..?

From: "Paul"

Any ideas?
Other than that pulleys perhaps?

I wouldn't recommend using a rigid sleeve. It makes alignment too critical.
Use something like a Lovejoy flexible coupling. You can get one end with the
5/8 bore and one end with the 1 1/8 bore and a neoprene spider to go in the
middle. That way it only takes a few minutes to bolt them together and line
them up without having to get the two shafts in perfect alignment.
