I've got a cast epoxy widget about 6 inches long x 2 inches wide x 1
inch tall.

It's cast in a mold and has a sharp edge around the top from the
casting
process. I want to remove this and shave maybe 1/16" off the top.

The sides are sloped so I cant grip it in a vice and machine it
under a
milling machine.


I came across drum sanders and wondered if something like one of
these
might work?

Generally the best tool for sanding a 6" piece like this would be a
belt sander. The fence holds the work piece from flying off and a
heck of a lot cheaper than a drum sander.

Something like this:

And then you need a planer to make the surfaces parallel again.

If you're not measuring with a micrometer, you can do a pretty good
job eyeballing it on the sander then checking with calipers.


Absolutely, you could get close, maybe close enough that it would not
matter. But if the OP will be investing to buy a planer or drum sander
he may intend to surface more pieces than you would ever want to
eyeball. ;~)

If he is in a production environment, he should call his tool provider
and ask them what's the best tool for what he wants to accomplish, not
asking a bunch of hobbyists and garage/basement dwellers that can spend
weeks arguing over the best way to drill a hole in your bench top for a
bench dog. They probably have a vacuum table for his milling machine, or
perhaps a nice CNC machine that will turn 100's or 1000's out every day.
