Thread: a chance for a laugh

There is no reason why you couldn't use one and in fact you could probably set up a table and use it as a double sided disc sander for timber although you would have to set up some sort of dust extraction though.

This exact question was raised a little while ago.

The problem with them, besides the fact they go a squillion miles an hour, emeries (cloth backed) are horrendously expensive, they are more expensive to buy than a normal grinder, and no shearer worth his salt will let you play with his fine tuned grinder.

Wait for it.

The problem is the discs are tapered from the inside to the outside, only a bit, but enough so that combs and cutters when ground have a hollow in them. Really really important to shearers to have this hollow, awful for anyone who wants a flat ground whatever.

Hello Outback,
I can get a sunbeam grinder, plates etc for nix, I tried the glue on floor (drum) sander papers and it worked & pulled off cleanly. The speed varies with where you hold the item on the disc but the local electrician says he can fit a controller to vary speed.
The killer is the discs not being flat. I wasnt aware of that, never gave it a thought. Bugger. I might put a straight edge on them and see if a skim on the lathe will leave enough disc to be workable. Thanks to both for your input. Bill

If you only use the insidey bit so things don't go too fast you are only using a poofteenth of its abbility.

After your update i would.
Get the slowy downy thing from the eleco.
Whack the discs on a lathe and flatten them, the taper is only a couple of degrees.
Make sure you add grrooves again during machining to allow for a good solid glue application.

Grind a way, you may well be on a winner for the price you need to pay.
