   Whatever pulley you had on the original motor, you need one half the diameter on the new one.
   This will mean the saw runs at it's designed speed.

   That would be a 1 1/4 pulley, probably too tight a bend .

   You can also increase the size of the top pulley. I suspect that the original design speed was influenced by the limited power of the motor. You could probably run it a little faster, maybe with a 10" top pulley. I wouldn't try double speed, however. I agree that putting a 1&1/4" pulley on a 1 hp motor is likely to produce power transfer issues. The important thing is the ratio between the two pulleys.

   I just measured the pulleys on my 14 inch Laguna, for a 3450 rpm motor the drive pulley is 3 inches od and the wheel pulley is 11 inches, a ratio of 3.8. For a 2 1/2 drive you would need a 9 or 10 on the wheel side.
