ro 90 sanding pads on a multi master

[Alan m]

hi guys

i have a multimaster . i would love a rotex 90 by cant afford  one yet ( but saving very hard). i have a rotex 150 that i use for the main sanding. i have a few jobs to do where the delta pad ( or whatever the MM triangle pad is called) would by ideal. this will only be a short term thing until i get the ro90
i dont like the fein paper on the MM as the velcro part comes away from the sandpaper part. i went to my local dealer and bought a few ro 90 round padsin granit 80 grit (didnt have any delta pads )the problem is that they dont stick very well. the pad osilated but the paper stays put. i think the fein hook or the pad is not as aggressive as the festool hooks on their pads

1st question . should i stick with the fein paper
2nd .              why is the festool paper not sticking
3rd                would rubin or brilliant stick better.
4 th                i was thinking of making a interface pad , this would had the fein paper epoxied onto a piece of festool sander pad

any advice would be greatly apprieciated

Company I worked for got me some sand paper and he knew I liked festool so he got me some festool sanding paper for my fein they where I cant remember but I had to cut them into triangles well they where rubbish!  

I was very disappointed and so was he.   I didnt own a festool sander at the time so I didnt know better!  Any way the festool pad didnt even last 2 seconds!  Then like you said the pad on the fein oscillates and the sandpaper just stays still.  

IF you keep going for a few more seconds the velcro on the festool sand paper just comes loose from the sandpaper and your left with all this Velcro stuff  left stuck to your Fein pad and its a right pain to remove.

My first opinion was man festool sand paper is crap it cant with stand the Fein power!    

I have found out after buying many types of other brand sand paper for the fein  that Fein sand paper is really to only sand paper tough enough to with stand the heat of the fein oscillating.   If you keep pressure evenly or alternate the pressure on the fein the Fein sand paper outlasts any sand paper you can buy.    

When I bought my Rotex 150 I was thinking is it a good idea as Festool sand paper is CRAP! well I was wrong when using the Rotex 150 I found the sandpaper stays on the Rotex no problem!   Sooo I dont know why Festool sand paper can not cope with the Fein or many other brands out their cant.

thanks jmb
i presume it has something to do with the hairyness of the backing or something similar. looks like i will just have to buy some of the fein paper.

I agree!  The festool sanding paper hairs feel softer than the fein.  Also I think the glue or what between the velcro and the sand paper is better on the Fein than the festool.    I never had a Fein sandpaper come away from its ''hair'' velcro  but the festool separated in seconds and I was left with two pieces a bit of sand paper and a cloth like material  and this cloth like material velcro stuff  if you end up getting it stuck on your Fein pad you might aswell throw it away and get another one cus I was picking at it for ages and even though I got the thick of it off I still had a lot on which was clogging the velcro so even my Fein pads wouldnt stay on well. 

I have 4 boxes of this other brand which I got from my local dealer and he said they are just as good as the fein. I looked at them and they look just like the fein ones so I said well they are like half the price so why not ill take 4 boxes!  Man they where rubbish okay lasted longer than the festool ones but not as long as the fein. 

I now just buy Fein sand paper for my Multi master.  If any one else knows any other brands which work just aswell for less cost then ill be happy to try and test it!

You cooked your pad, rotate to get more life and try to ease up in the future.  I don't sand past 1/2 power with the MM.

BTW you can get a 125mm round pad for the MM that works pretty good.  I think the Fein paper outlasts the paper for my DX93 by a factor of at least 5, but it's more expensive too.

 

[Alan m]

the pads not cooked as it is almost new. the fein paper sticks perfect. i have the 125 mm round pad , i think it leaves funny marks . i only want the fein to do the corners and tight up against things , my ro150 does most of the work.

My guess is that the hook and loop sets don't match between the Fein and the Festool, which is why the Festool paper doesn't move while the Fein is oscillating. If the sanding pad is oscillating and the paper is staying still, it's going to get pretty darn hot. It's likely hot enough to cook the glue and cause the separation.

You say that Tom and  Kevin but its does it so quickly that its hard to believe that its due to the heat melting it.  It does not take much pressure just slight use and it falls to bits.

If I can find some of the exact stuff I used ill do a video! I got some Rotex ones wish I will use also but the ones the company got me where large triangle ones for a festool sander and I got just 2 smaller triangles out of it for the fein cutting it with my stanley.  They where white as I can remember.  It was about 3 years ago now I think.

the granite paper i was using only moves a few stroke and stops . i dont think it is due to heat build up. mine doesnt fall apart just stops moving. maybe some of the other papers fall apart.

 

[tbellemare]

I think the reason it stops is that there is a mis-match in the hook and loop.

If the paper was white, it was likely Brilliant 2. It has the lightest backing but I've never had any delaminate. That's why I think it is coming apart due to heat.

I've used saphir a lot to shape limestone with both a Rotex 150 and a Deltex. I've never had any come apart but I have had the loops give out and the paper fly off the pad. That only happens after a lot of limestone had been pulverized.

can you get a small triangle of the festool pad that you could epoxy onto the fein pad

The Fein pad comes of the metal plate really easy.  Especially the one with the holes in it for extraction which I never use with the fein.  I was sanding some Facia in the corners and next thing the actual pad from the fein just flung off the metal plate.    All I had was this oscillating metal triangle plate good for making dents into the wood lol!

So if you could get a festool pad you can easily remove the Fein bad from its plate for you to epoxy the festool pad to it to fit on the fein.
