Thread: How to change paper on Carbatec disc sander

being former Velcro dealer I can tell you that the pre glued velcro is the way to go....the Velcro brand product.....the generic brands have always had adhesive issues.

Hook and loop material does not glue well with normaly available adhesives.

as for centering the piece of material...get it as close as possible then trim the edge with a turning chisel..I fnd a parting tool best...you want the hook materila jusy a little back from the edge of the wheel.

also...after you have applied the velcro materioal to the disk....run it over with a laminate roller or some other smooth round thing.

OH you must make sure the disk surface is clean....real clean..and dry of solvent.

cheers

Right !!! Well I hit it with the heat gun, and lifted the abrasive paper off nicely, but it left all the glue on the 12" disc. More heat, lots of scraping with a paint scraper ( no scratches) and then acetone and then turps and it all came up pretty clean.

but wait.... there's more

The disc had a number of raised spots on it, like pimples or rivets that had not been finished off, as shown in the attached photos. The largest raised dimple was 0.5mm proud of the surface of the disc. Carbatec suggested it might be counterweights the Chinese manufacturer used to balance the wheel.

I purchased this new disc sander with the purpose of trimming mitres for boxes, and for trimming corners and curved edges, and I am not sure how a 0.5mm raised point under the abrasive velour backed disc would go.

Any suggestions on what to do, or if a replacement would have the same problem? Is there a table mounted disc sander that anyone can recommend that does not have this problem?

I would welcome all your comments on this problem

G'day Joe. Did you laugh when the Carbatec guy said that the dimples might have been added to the disc face by the manufacturer as counterweights? (He had to be joking, surely?)

It's hard to imagine that they'd go to the trouble of machining the face flat, then adding dimples to the flat surface for balance, defeating the purpose. It does make you wonder how they got there though, after machining.

Personally, I reckon I'd be pulling out the Dremel and grinding the dimples flat.

Thanks for this advice, Hermit, but I am not sure what is causing the dimples, counterweights perhaps?
