I need to know what speed to drill glass on my drill press. Also I am having trouble changing the speed....HELP!
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!

There is a little bearing that rides in a cam for adjusting the belt tension. It's probably shot. Good Luck!

Hi there,
Unless you have the part in hand, which you could take to a specialized machinery or spring supplier to see if they could match it up, the only other way to get the correct part is to contact ryobi direct and talk to their parts department. They will be able to tell you the part number, and if available, send you one out direct from their warehouses.
Good Luck!
Testimonial: "Thank you very much for taking time to help! I have phoned Bunnings who I think are now the only suppliers of Ryobi in AU who are sending a spare. "

I would go to Dewaltservicenet.com and you can download a breakdown and also user manual for this tool with information about the set up and belt assembly, the breakdown would show you how everything is supposed to go in the pulley section. L et me know if you need further help

Are you talking about the chuck key? That's the little wrench with a collar of gear teeth on it.
There are only a few standard sizes plus a couple of odd-balls. Last time I looked, Sears carried a good selection. If you have the old one, take it with you to the store. If you don't have the old one, find a way to measure or approximately measure what you need. Another chuck key that doesn't fit can be a useful reference. If you can find something (maybe a drill bit) that is a close fit into one of the three holes in the chuck, that can be useful too.

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
