Hmm....My 1.5 hp J head is 1740 rpm, and both of my BOSS heads are 1700 rpm. How did you get a 3450 rpm motor?
So the top of the spindle has a round piece attached to the top. This round piece rides (spins) in a bushing, and also moves up and down 5" as the quill moves up and down. So the top of the spindle shaft is supported from whipping and still is allowed to move up and down. Am I getting this?
Any chance of a pic?
Trying to visualize what you did...
Thanks Mactec.
Your head rebuild is a work of art....If I could only do the same.
