My fellow LJ’ers,
I have owned a Bosche 5” ROS that has served me well with one exception. The “hooks” on the pad seem to wear out and the sand paper disk migrates out from under the sander. I have replaced the pad (soft) in the past, but here we go again. The question is, is this common to all ROS’s, just the Bosche, should I use a “hard” pad, or am I just using an inferior brand of paper? Your response is greatly appreciated.

I think it is an issue with the Bosch. Although I have the Bosch and a Dewalt sander, and have never had those issues with my Klingspor sandpaper. Still, I have heard that complaint about the Bosch several times.

I have had a Bosch ROS for about ten years and a Porter Cable ROS for about fifteen, and, like you, I have replaced the pad on the Bosch, never had to do anything with the P-C but replace paper.

Greg, I may be totally off base here but that never stopped me before. :D I think that the heat generated by sanding causes the hooks on the Bosch to melt and therefore lose their gripping ability. This can be caused by pressing down while sanding and/or having a too powerful vacuum attached to the sander. I replaced my Bosch with a Festool and the instructions for that are to reduce the suction of the dust extractor. I haven’t had any issues with the Festool.

Another possibility is that different manufacturers use differing hook designs and some papers cause the non-standard designs to lose gripping ability sooner. Bosch may be one that is different.

I don’t think the issue is due to using a hard or soft pad. A hard pad will cause more sanding because it will be less forgiving of any minor surface variations. If you find a definitive answer, please post it because I have an otherwise usable Bosch sander and a bunch of disks to go with it.

I have had the same issue. Instead of buying a new pad, I replaced the hook with strong adhesive backed velcro.
I used 3M77 on the original pad. I previously carefully removed the old hook.
Works like a charm and it did cost $2 (got the velcro at a craft store). Once well glued I cut the hole on the glue velcro.

I agree with Art.
The hooks are getting hot, and losing their shape. I did that a couple times years and years ago, before I knew any better. And it was not on a Bosch.

My problem with one of my Bosch units is the actual hook pad is losing its adhesive grip on the soft pad. The adhesive is failing a bit around the edges. My other Bosch, newer but used just as much, suffers no such problem.
I’ll be using Goop soon to reattach it and hopefully that will take care of it.

I wonder if you could be putting too much pressure on it when you’re sanding??? Just a thought

after burning through two pads on my dewalt ros, i did the same.put an old 60 grit belt on my benchtop beltsander and got rid of the old velcro first.no problems since and its been about 3 years and lots of sanding.
worked so good i added velcro to my 6” disc sander. disc changes are real simple now.

Thank you all who have responded to my question. I believe Art (AancCstyle) diagnosed the problem first. I have never been accused of being a patient man and it is not a great leap to conclude that I may be bearing down to hard and melting the “hooks” off the pad

Lepelerin came up with his solution of replacing the pad hooks with a glued Velcro which I believe I will follow. If that doesn’t work, I can always spend another $15 and 10 days on a replacement pad.

Lesson learned; let the sander do the work in it’s own good time.

Thank you all once again.
