Like Martin I bought one that clamps onto an angle grinder. Man at a long ago Model Engineer Exhibition convinced me that it was best thing since sliced bread. Um. Nope! Hopeless, belt would hardly stay on long enough to bring it up to the job. Put it on the white elephant shelf and had a few goes at it over the next decade or two but never got it to go any sense.
Clearly there are different breeds so it looks to be a toss up whether the one you buy works or not. 50-50 so far. Martins does, mine doesn't. Next …..
Got one of the Parkside variety from Lidl which seems OK.
