Models for grinding HSS Lathe Tools

Good job, Dave! Now go make a Square Tool - that will outperform a knife tool for general use any day.

I misspoke, I tried to copy the square tool but angles were a bit off.

There's definitely a knack to it!
Keep at it though, the payoff is unbelievable!

I don't have a belt sander, so bench grinder is a little trickier.

It would be a bit trickier. I think the rest makes a big difference. I also have a bench grinder so I want to try on that as well. The top rake was tricky to grind on my belt sander because the platen is about 1/8" wider than the belt so the belt wants to push away from the tool. I have some mods in mind to fix that problem.

I put diamond wheels on my bench grinder just for that reason Dave. Every thing is done on my belt, even the top rake I just finish it on the wheel.

I thought I read that Diamond does not like tool steel ?

Do the wheels look like CBN wheels?

Not sure, I was not advised against it. Yes I was meaning CBN wheels.
