DISK sander/grinder... not a belt. Belts don't sand flat/straight; disk sanders do. READ.
Or you can goober you're DP and have 2 projects...
I don't care what you paid or didn't pay for a milling machine. I don't have room for a milling machine, I don't have three-phase power or a rotary phase converter. Why did you bother to comment if you have no information of any use? Just driving through and thought you drop a snarky comment? Noted...
I served my apprenticeship and worked as a journeyman patternmaker at CAT in the 80's. A disk IS the tool to straighten a metal edge. You don't just shove it up to the disk. The workpiece is started with only several inches on the disk and then lightly slid across... much like feeding wood stock into a jointer. It doesn't take long to learn to straighten stock without cutting a taper.A disk sander eats faster on the outside edge though. It could work but you’d have to be careful not to taper the piece.
Done with this thread... this guy is a tool.
Why are you being so arrogant? And why are you asking on a Tractor Forum?At one point in my life, I owned a machine shop. It had multiple CNC mills, a Bridgeport, a Hardinge toolroom lathe, an EDM, a complete sheet metal fabrication area, and a plastic injection molding machine. The CNC machine tools were high precision and with careful setup and control, parts were regularly made with +0 / -0.0001 inch accuracy. I think I know the difference in how machine tools and drill presses work and why. I'm not trying to make repetitive movements, hold locations, surface milling, or hold precision tolerances. This isn't true machine work.
I can make my metal bandsaw hold tolerances of 0.003 with 12 parts having a miter cut at each end. You'll have to take MY word for the fact that I know what I need to accomplish this task and you don't.
