Sanding mop rpm - Scroll Saw Woodworking & Crafts Message Board

I have a 1725 rpm washing machine motor in good condition with a 1/2" work arbor on it. Would this be ok for use with a 6" diameter sanding mop or do I need a 3450 rpm motor?

I use a 1725 rpm on the drill press. I doubt you'd want it going any faster than that. Things fly pretty far with that speed! Also takes off thickness of fingernails pretty good too. I think you're fine with that motor.

I'd agree with Janette, That should be plenty fast enough.
If you have them spinning to fast they tend to burnish not sand.

................. What is a "sanding Mop"? Like a flap wheel? New term to me.

Thank you Janette and JohnB for your replies. Jim Finn, I didn't know what a sanding mop was until recently. Here is a link to a thread describing how to make one: Making a sanding mop--- A sanding mop is somewhat similar to a flap wheel. If you Google for sanding mop you will get many hits on what one looks like.

rja, Klingspor sells sanding mops and the arbors that go with them. Check their web site at Klingspor's Woodworking Shop,klingspor's,Klingspor's,woodworking,supplies, tools,proxxon,disc,sanding sleeves,sandpaper,belts or call them at 1-800-228-0000. They are good people to deal with. Not cheap but worth it. I use mine on the drill press at about 1000 rpm. Listen to what JohnB and Janette said. Absolutely true. You can get a type of tape that protects you nails but I find it makes me a bit more clumsy than usual. Slower speeds for sanding mops and flap wheels are better than faster.

Thanks for the info on sanding mops. I see what they are and how they are used but I am not sure about any advantage to them as compared to other sanding tools.

I use a 6 inch on the end of my sand flee (1725 rpm)
According to Stockroom Supply they recommend a higher RPM. This is from their web site. I am not sure that I agree with them.

"One thing to remember about the mop is that speed is the key. The faster you spin the mop, the longer they will last and the better they will work. 6" mops need to be spun between 2000 and 3500 RPM's. 4" mops need to be run between 4000 and 10000 RPM's. Cordless drills and some electric drills do not have the required RPM's to achieve optimum results. "
