Models for grinding HSS Lathe Tools

[mikey]

Mikey i love the instructions. Great work. Im going to make aluminum and brass cutters from this. Im thinking of making both tools for each material.

Thank you, Brento. When you grind the brass tools, leave the top of the tool flat and just hone it; the tool will work great for brass. Let us know how it goes.

So dont create any rake for the brass tools?

I'll post pictures when I get some graphite turned. I'm building a dust capture setup before I try turning it.

Watching Clickspring videos, no rake for brass. I haven't tried it, but he gets great finish that way.

Ill draft up my tool bits so i get an idea of what they look like. Not sure when i will get around to grinding them exactly. Still need to finish my other threading tool.

Nope, just grind the side and end, then hone it and put a nose radius on it.

My models arrived today, thanks very much. Waiting on some new ceramic belts to come in. And I need to order some HSS stock to make my copies. Any reason to not get Cobalt? Recommendation for best place to get my blanks?

Also, my lathe is a Southbend9, but has the QC toolpost and holders. The tool holder's slots are horizontal (same plane as the bed). It that compatible with these models angles?

I would get the least expensive HSS bits to start with. In fact, Mikey recommends getting cheap key stock for starters just to get the feel for grinding. There will be a learning process. Get comfortable cutting the key stock then move to HSS, save the cobalt for down the road, just my opinion. I’m sure Mikey will be along shortly.
Enjoy

Ik this isnt the correct spot to ask this but ik everyone has been talking about building belt grinders fir this very topic. Did everyone build theirs from the fly or did they have drawings to go by?

Both actually. Bob, rac1812, built his from scratch as I believe ttabble did. Not sure of the others. I found some drawings for a KMG clone that I used. A lot of drilling and tapping involved but I don’t have a wire feed welder so I went that route. I used a 3 hp treadmill motor on mine.

Thanks Jeff, I ordered some M2 at MSC for $3.67e.
