cannot remove rotex 125 sanding pad
« on: June 23, 2018, 03:32 AM »
I just cannot remove the pad from my 125mm Rotex no matter how hard I try.

I have no problems with my 90mm and 125mm Rotex sanders.

Although I have had the sander for years, I haven't used it that much. It used to jump and bounce around all over the place, so much so that I eventually only used it with an interface pad for sanding 2K paints on MDF. I guess that I should have returned it as faulty but it was quite some time before I got to use a friend's 125 and realised that mine is badly balanced.

My last attempt to remove the pad ended up with the velcro and foam backing sheering off, leaving just the plastic base.

I guess that I am going to have to use an oscillating saw to remove it. Can any one post a picture of the sander without a pad fitted so that I know where to be careful when cutting, or can anyone recommend an alternative way of removing it?

Many thanks

Hello Imaginarynumber.

I hope you can remove the pad without damaging the sander.

Here you are a pic.

Considering the backing of the pad is plastic, mounted into metal, have you thought on heating the plastic with something and trying to remove it instead of cutting it?

Regards.

Great, thanks Milvus.

With your assistance I finally managed to remove it. I used a combination of cutting and then wide jaw pliers.

The new pad goes on/comes off with ease.

I am hoping that the replacement pad will help to reduce the bouncing. Need to order some more paper first!!!

Once again, thanks for your help.

You are welcome!

I’m glad that you manage to undo the old pad.

I have the same problem as imaginarynumber did, in case anyone has a solution.  My hope is that my problem is insufficient grip on the pad.  So far the problem is academic; I haven't needed to remove it, I just wanted to, because I bought another pad when I bought the sander for when it became appropriate.  My intended solution, when that day comes, is to fashion a jig to more easily apply more torque to the pad.  It will consist of a board with a pattern of dowels to match the pad's dust extraction holes that I can clamp to the work bench   Anyone have a better idea?

The jig would also be handy for aligning sanding discs to the sanding pad so I might as well just make the darn thing.

Cheers - Gary

That is a good tip if it's as easy as Sedge makes it look. I really struggled trying to change the pad on my RO150 with my small hands.

I had previously tried the technique used by Sledge- it didn't work.

I genuinely do not believe that I was being weedy. I was lucky that my pad had disintegrated shortly after using Sledge's technique, thereby enabling me to use slip jaw pliers to grab the centre of the pad. Even then, I still had to apply a heck of a lot of torque to release it.

281150-0

My rotex is dated as 2008. I noticed that the original backing pad is listed as 108071 (PA6-GF50/PUR<W-HT). The new pad has the same description but a different code (246173). I cannot see any obvious differences between the two pads, but it may be the case that the first generation pads were difficult to remove.

As much as I like (read: obsessively buy) Festool they do remind me of Apple in so far as Apple are too arrogant to admit that they  could ever be guilty of design faults and in the event of such faults arising the company line is to disavow any knowledge of  similar complaints.

Hi Gary,

I hope that the jig works for you. Perhaps you could talk to someone in China and develop an after market product.  ;-)

Near one end of a 12" scrap of 1x2 or the like, drill two holes that are 3 1/2" apart.  The holes are 5/16".   Insert a couple of 5/16" dowels through the holes.   Use this "wrench" to remove the pad--much easier than trying to twist the pad off by hand.

Correction --  the two holes are 3/8" holes --  and use 3/8' dowels.
