I slow my variable speed ROS down for for more control when sanding narrow edges or convex surfaces where it really wants to start dancing around. I tought I'd use it more for leveling finishes but it it's pretty worthless for that. 220 sands through near edges in a heart beat and 320 loads up just as fast.

John, here's a little trick I discovered by accident. Put the piece to be sanded on a piece of shag carpet. It acts like a shock absorber and gives you a lot more control over the sander. It lets you float the sander without letting it go into full spin cycle.John
You still have shag carpet? :o)
Yep, just couldn't throw it out.. Its the only part of the 60's that I can remember. I think its the smell because most of the time I was face down on it.John
Oooh. Brings back some bad memories. :o)
Handy for wet sanding of film finishes, slow speed that is. Mirka, I think it is, produce wet and dry abrasive disks backed by foam and the fuzzy half of velcro that can be be mounted to the sander's disk. Mirka may not be the only producer of these abrasive disks. Slainte, RJ.
Slower speeds are required for material hogging on rough wood with coarse grits. The sander is just too difficult to control at higher speeds, and really gets hot.
The shag carpet smell triggered another memory - there's nothing quite like the taste of a warm, flat beer in the morning that has a cigarette butt in it. John O'Connell - JKO Handcrafted Woodworking

ROFLOL... No shag this time, Berber. Sure glad chew wasn't popular then...Steve - in Northern California
LOL. This thread has taken a nostalgic, and disgusting, turn. :o)
Yes, it has.. I think its time to get it back on track.
2 speed ROS's is there any advantage - Most certainly there's the bragging rights. My ROS only has one speed and I've learned to use it with different pressures to achieve the results I desire. A slow speed that wouldn't cause the pad to take off spinning instead of orbiting would probably be a big help in eliminating gouging with coarse grits.Steve - in Northern California
I was thinking about the 2 speed ROS. I figure if I'm gonna buy a tool, I look as to how I might want it to perform in the future so I usually "buy up" so I don't have to buy again in the future.
I agree - You just have to watch out for the old marketing scheme thing. If one speed is good then people must think that two are better. In this case, I would probably buy up if the addtional cost was not that great. The tools performance at high speed should not be any different than a single so it should work the same in that regard.
However, the only way to beat the two speed would be a variable speed and you gotta know its comming down the pike. Maybe we should recommend that he buy the single speed now and then replace it with the variable when it comes out. I don't know if thats logical or not. I'll probably wait for that option versus the two speed because I already have the single speed.Steve - in Northern California

This is one of the one's that I was looking at and was the top consideration for the multi-speed version. I think the cost difference at Home Depot is about $25.
I would say it is well worth the extra 25.00 and would buy it instead of the two speed.Steve - in Northern California
It's nice to see PC wized up and went to 5"/8-hole. Now they're in the same camp as Makita and Bosch. If everybody standardized on the same hole patterns for a given size then more places would carry the disks. John O'Connell - JKO Handcrafted Woodworking
