Topic tags/keywords: sanding festool rotex domino finishing question sander modern traditional greene and greene shaker

I have recently been bitten by Festool bug and i do not regret it! The Domino, CTL, and MFT are the best combinations for productivity and accuracy that money can buy. I am more interested in doing good work than bragging that i did it with less expensive tools. Heck take advantage of technology! After all, im using the internet!
Anyway, I also have the Rotex 125, which i really like. Sometimes when using it, it tends to jump around a lot and can damage the material. I have tried slower speed and reducing the speed of the vacuum too, but it still jumps around. This is only in rotary mode, of course.
Can anyone tell me what to do to stop the jumping? I really love this tool (after all, sanding IS a major step in finishing) but i know 2 things (1) I can do better (2) i can do better by askign my question here-with the finest woodworkers alive.
Thanks in advance for your time and thoughts.

You’re not alone. My Rotex 125 jumps around on occasion also. I don’t have “the magic answer” but I have a theory and an opinion.

I think the problem is primarily attributable to not applying even downward pressure and/or applying too much downward pressure. Many ROSs have the weight of the machine centered directly over the sanding pad. With the Rotex, the weight is off to the side. Because of this, the downward pressure on the sanding pad can, more easily, be off center and this will cause the sander to jump.

I try to deliberately hold the sander so the pressure over the whole sanding surface is even and I am learning that not much downward pressure is required. As they say, “let the machine do the work”. In this case that means light sanding pressure.

By the way – you do need to cut back on the amount of vacuum from the dust extractor. Too high a setting will, effectively, suck the sander down into the wood creating more downward pressure than desired.

I’m glad you brought this topic up. I bought this tool two years ago and it bounced all over the place. I consider it my worst tool purchase ever. The power cord comes off very easy also. I’ve since stopped using it for most projects and give it a try now and again due to its cost but I use a $60 Ryobi instead. Hope someone offers up a good answer because I’m considering ebaying it.

I do the same thing with my OR 125 and have very few problems with it.

The answer is balancing – ti;t it up – intentionally or unintentionally – and it will bounce because like any similar it is on the forward edge.

As to pressure, you really shouldn’t be applying any significant pressure – let a lower grit do the work, and lower speed will help. I have little bouncing with attention paid to balancing. Great product particularly with vacuum and lower noise level and pitch.
