I'm working on building a multi wheel buffer (2-4 wheels sewn and lose) and I currently have a 1Hp 1725 and 1.5Hp 3450 motors on hand. I was leaning towards the 1.5 3450 but after reading some other information on the use of buffers was warned about having too much HP and RPM.
I can fully appreciate the need to be safe when buffing as I have had more that one item jerked out of my hand while buffing.
I just wanted to throw this out for input as I am now thinking that my Hp on the on hand motors is too much???
I have three customers that are custom knife makers - all 3 said to use 1/2 to 3/4hp at 1750 rpm for 6" to 8" buffing wheels... if you go with a 1725 / 1HP to use 8" to 10" wheel ( 10" for more surface speed and a little less torque)
Also said be careful and aware that the "loose" wheels are the worst for grabbing something out of your hand.
