Hi,
I need to cut some strips of 6mm MS and have them to a reasonably accurate width, various widths too so it's not easy to simply buy it in...
also I wanted to put a fairly accurate 60 degree angle on some of it, and on some 10mm MS. Three of these needed to be as close to 'spot-on' as I can get it as it's to mate up with 'ways' and 'cross-ways' on the lathe that I'm starting to re-build.
So I looked at making some sort of jig, maybe similar to a router table as used in woodwork.
I had a piece of plate that came off a pallet at work, around 39" x 8" and 5 - 6mm thick. This cut up nicely into two pieces around 12" long to make a base and the remainder, around 18" would make the table. A grinder could be lightly clamped over to one side of the base, and angled so the workpiece missed the guard. I could then twist the grinder to get the angle on the piece.
That was the basic plan and making it up as I went along, I did this...

Initially I had a piece of angle for the work-guide and simply clamped in in place. But then I thought I could do better and came up with a clamp at each end with 13mm bolts. Also a couple of threaded adjusters where I could move the guide by around 0.5 mm at a time to take shavings off the metal with multiple passes.

Three of the angles need to have the concave taken off, not sure yet how to do that, possibly using the sander? Maybe a sander disk on the lathe and a jig bolted to the bed when I get the head-stock built?
I've read about a metal scraper, flat steel with a slightly raised sharp edge apparently, that can take small amounts of metal off but not managed to find one yet as I'm not sure what it's called...
