yes it is. mine has a 5" drive wheel. assembly took about an hour. i have metal available thru the office so i have an extra tooling arm to work with. if you shop and have patience, you can find a motor/VFD for $200-300. 1hp is more than adequate. Wilmont also offers a belt drive attachment which might be the way to go.Is that what you did? I was thinking about getting the LB with no motor and fitting it with one as an option.
