So I'm in the shed and the time has come to use a piece of 16mm plate that I've had for a few years. The 250mm x 1300 long plate was cut with oxy lpg and it was my first attempt so the edge is terrible.
After grinding most of the slag and dogs off (cutters don't like that stuff) I find a piece of reasonable sized steel that is reasonably flat and tack weld it to the plate roughly square to one of the sides. This becomes my reference to DI off to get it close to parallel on the mill.
I can edge mill about half the length at a time before I have to reset and re-clamp to the table after once again indicating from my reference bit of steel.
Ignoring the wear on the mill, I reckon I get it within about 10 - 15 thou of straight.
Anyone else know of a better way to mill the edge flat on a piece of plate that is longer than the working envelop of their mill?
Obviously I'm not talking micron accuracy here, just to neaten the edge up.
