I have HF's bandfile attachment which fits onto your 4" grinder. The

I've got the same thing, but I find that the belt slips off no matter
how much I try to adjust it. So basically it doesn't get used...

That gadget is on my "next order" list, but your comment puts me off a bit.

I wonder if adding a bit more crown to the belt pulleys would help?

(I have to go through a "mind experiment" every time I tried to explain
to someone how crowned belt pulleys do their thing.)

Maybe the driven pulley could be altered as simply as holding a file
against it while it's running with no belt installed?
