SOURCE: My Powermatic drill press model

Hi, this is happening because the belts are shinny... true.. well and a little stretched... you see what happens is the belts are slipping over the Pulleys when the drill bit draws and bites on it hard.. the Fix if you will, is to A: Replace the belt... Or B: Tighten the belt, & roughen up BOTH surfaces a little to improve traction..
This usually will only be a stop gap measure though, as this really means that you need a new Drive Belt(s) as the existing one(s) has stretched too much, and has lost it's grip. belts only have to increase their size minutely to just loose that edge that a newer one has.

SOURCE: Need a chuck key for model 1140b,f powermatic

There are only a few sizes of chuck key. Easiest thing to do is first find a drill bit that fits in the hole where the key goes to determine the size of the pin on the end of the key. (Use the back end of the drill bit.) Then take any other chuck key you have and see how closely it fits or doesn't fit - just as a reference. Take the reference chuck key and the drill bit with you to Sears or any place that sells a good assortment of tools. You will probably be able to determine the correct size key from what they have available very easily. Good luck, Al K

SOURCE: Changing speeds on Powermatic Drill Press

Katie,
Refer to the picture below. Loosen the locknuts (the one on the right side of the drill is shown, there is another on the left side). Use the lever to move the motor toward you, thereby loosening the drive belt(s). Open the top cover to expose the belt(s) and sheaves (most people incorrectly call them pulleys). You might have one belt and two sheaves, or you have two belts and three sheaves. The drill will go fastest when the belt is on the biggest motor sheave and the smallest sheave on the drill spindle. Of course the opposite sizes apply for the slowest speeds. Make sure the belt uses a pair of sheaves that are at the same height as each other (the belt has to stay in one plane). Now tighten the belt(s) by pushing the lever pretty hard away from you, and while holding it with your right hand tighten the left side locknut with your left hand. Now tighten the right locknut. Close the cover. ----- OK, so now you know how to CHANGE speeds, what about drilling glass? This can be tricky. You must use a pretty slow speed (maybe the slowest, depending on the size of hole you are drilling. And you must keep the spot you are drilling flooded with water to keep the glass cool. And you must apply pretty gentle pressure. And the use of a drill bit intended for drilling glass helps a lot. And don't try the first hole in something expensive! Practice on something disposable first. Take your time. AND WEAR SAFETY GLASSES!
Good luck!
