Dengy,
There are two things being discussed here. The disc cement that was mentioned is a Bear product and you apply it to you aluminium disc and use ordinary plain backed sanding discs. You will get about 5 uses out of the glue before you have to relace it.
The best way i found when i fixed the disc on the end of my Multitool on the grinder was to buy a sheet of non adhesive backed velcro, cut it oversize and took them both to, i think it was Ross Joinery, and they sprayed the good contact adhesive on both surfaces in an even layer and it turned out perfect, no bumps or ridges as mentioned. Dont trust the pre glued velcro. If thats all you can buy, remove it with acetone.That was about 3 years ago, and it is still working fine.
Rgds,
Crocy.

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.

Most powertools have sharp teeth.
People are made of meat.
Abrasives can be just as dangerous as a blade.....and 10 times more painfull.

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.
regards,
Dengy

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.... Steve

Thanks for this advice, Hermit, but I am not sure what is causing the dimples, counterweights perhaps?
I made the mistake of copying this latest problem to a new thread, but forgot to delete the original from here. So have done this now. You will find the new thread hereregards,
