I need to sharpen a lot of commercial mower blades. I currently use a classic two wheel
bench grinder light duty. I want to make a jig to get an even, quick and constant result.
But the god darn thing has no tool rest and it doesn't really make sense to adapt something.
I'm not sure what kind of steel, other than "1/4" (6.4 mm) thick heat-treated steel" that sells
for about $50 USD for a set of three.
Should I buy a beefy heavy duty bench grinder or a decent belt sander?

This is baby shit mang. I made these jig plans in my head in like 30 seconds, so let me know if there need to be changes.
You need to pieces of steel, one angle, one flat.
The circle thing is your grinder. You're gonna want to weld your angle piece to the flat one at the angle you want it cut at. Then use a clamp or vice grips to secure the blade to the jig, with the end you're sharpening hanging off the side so you wont be grinding on your jig. Hows that sound?

The simplest form of an adjustable blade grinding jig. Works better with a belt sander but with some steel and some bolts you can just drop yor bench grinders table if needed

if you sharpen with a grinder it has to be wet and low rpm. too much heat softens the blade. wouldn´t do

Sure mower metal is soft to begin with, they don't bother putting good steel on them
