Good recommendation. I do not have a drill press, but am saving this post for when I do.

Tom, But the only thing wrong with one of those is that you also lose HP to your motor. Like if you were using a .75 HP motor and you installed one of those you would lose more then 1/2 of your available HP, like 1/2 of .75 HP would equate to .375 HP really not enough to ream properly with but in all actuallity you would lose around 1/4 of the available HP, upfront, that you started out with by just installing one of those on your motor. Your motor would start out at around a .562 HP motor not a .75 HP. So if you were to use the speed reducer and lets say you wanted o run your spindle from 320 down to 160, 1/2 of the present spindle speed you would in essance be using only about a little over a 1/4 HP not the .5 HP min requirrment for reaming, that you realy would need to ream out a hole. If anybody wants to really reduce the spindle speed on their drill press I would recommend that you get a TEK CATALOGUE, and look under "FAN MOTOR[s]", and purchase a half speed motor, from 1725 RPM"s down to 850 RPM, like I did, and install it, plus you get your .5 HP Motor, min required for reaming, but you can also hook it up s a 220 V single phase which give you a lots more torque,no more HP but around twice the torque.

You might have a clearence problem but you can cut away part of the metal shield (for safety, cage the pulley after the modification). It's tough to get a multispeed pulley like the one supplied with the drill press but you can get drill presses that can be modified for $40 and designate that tool for reaming heads. --- Incoming mail is certified Virus Free.
