Dremel Tool Problem

The picture shows a sanding drum about 1/4”OD by 1” long. On the right is the original (rubber drum) I had but after some use the sandpaper which was attached to it peeled off. I tried to put the replacement sandpaper which came with the set and is shown on the left but there is no way to slip it on. Is there a trick or something to get the new sandpaper into the rubber drum?

Usually with a Dremel bit..... there will be a 1/8" shaft to go into the tool.
On that rubber drum.... you'd loosen the center screw so that the rubber shrinks.
Slide the new roll on it and re-tighten the screw.

Drum sander

The screw threads into the end of the shaft. As PJ mentioned, when you loosen the screw (but don't completely remove it as you have) the rubber should shrink just barely enough that you can get the new sandpaper on. Then tighten the screw which will squeeze the rubber between the shaft and head of the screw causing the rubber to squish out (get bigger) and hold the sanding drum in place. There should be a washer under the head of the screw.

I did all that and there is washer under the head but have a hard time to get the new one into the rubber. Will try again. Thanks

The rubber drum may be getting old and hard. It won't shrink as well as it used to.

Its true Pete, the rubber drum is old but has never been used before. I have this Dremel set for about 15 years but never used it for any sanding. The rubber has expanded in the shape of a cone (perhaps from the heat when I was sanding) but I was able the push the new sanding drum up to about 2/3 of the rubber. That will do it for now. Think will have to buy a new rubber drum

Try using a little force to the rubber drum by rolling it between 2 pieces of lumber then putting it in the freezer to shrink slightly while the sanding sleeve is warming to around 120°F with a hair dryer or similar heat source. Even thought there is a law suit over Talcum Powder, apply a light coating to the inside of the sanding drum in case the rubber condensed a little moisture when it's removed from the freezer.

Considering the amount of sanding I will be doing, I purchased this set:

It should be more than enough to finish my project which is building a wooden clock from plans I got from USA. I think the trick to make the sanding disks last longer is to avoid excessive heat on the disks.

Hey mate.
I bought one of these for my Millwaukee rotary tool (Same thing as a Dremel)
https://www.dremel.com.au/au/en/drem...and-742-ocs-p/
It works like a charm.

One other things i bought that is the best thing ever for it is the chuck:
https://www.dremel.com.au/au/en/mult...2mm-215-ocs-p/

I would never go back to the collett type thing that you get with it.

thanks =)

Looks pretty nice this chuck, thanks.

I didn’t know about it and its true what I have now it’s a real pain.

Do you know what’s the difference between this chuck and the Dremel EZ Lock?

Thanks

The EZ lock is just the the bit that you put the sanding drum onto.

You put the drum over it and then push it down and the drum then locks into place.

The Chuck stays in the Dremel tool instead of the mandral thing.
You can use the chuck with any of the dremel attachments, it just makes is easier to change tool bits and also it adjusts to any size so you never need to change it.
With the mandrals there is different sizes for smaller and larger size drill bits etc.

I was not sure but now its all clear (I guess). With the chuck I can use all the bits I have now but with the EZ Lock I got to buy the ones which fit the EZ Lock. The Chuck will be better in my case. Thanks

With the chuck you can use it with everything - All your old ones and also the EZ lock.

I have a Dremel clone the Black + Decker RTX I got mine about 20 something years ago back when I was 16-17 I was into computer case modding.

I did my fair share of sanding stuff one the sanding disc breaks on the drum (either from age or overuse) the drum is usually gone and will have to be replaced.

My RTX is one of the last good models before they cheeped out mine is 7 or 8 speeds (Don't remember off hand and I don't feel like getting it out of my storage place).

The newer ones are made in China and are only 3 speeds (HI-MED-LO-OFF).

The beauty of these clones is you can use the real deal Dremel branded attachments but the off brand one are fine I only buy the actual Dremel ones for the high speed cutting discs & wheels.
