need to reduce the speed on the drill press below 500 rpm
It sounds like your drill press may have only 1 belt that goes from the motor to the quill if this is the case you might add a second stage groved pulley like in the photo below
Never try to tell me it can't be done
When I have to paint I use KBS products

That is the way I will have to go. Grizzly has a pulley and shaft to mount with. Will be calling them for the height of their Pulley. If it is the same, will go with their parts and slow it down.Originally Posted by Frank S

Grizzly pulley, p/n P7943067 is for a 3L belt, the two pulleys on the Atlas DP220 are 4L(1/2"). I found a 4L pulley but need to adapt to Grizzly P7943063 center shaft. What bo= "Pin It")
