That's an interesting tool holder and I may make one for myself.
For now though, I part off by running the lathe in reverse with my tool on center but mounted upside down and that makes the tool push away from the work when it grabs instead of digging in, plus the chips fall downwards out of the way immediately. Rigidity is an issue on my lathe and this technique minimizes the effects of it's absence.
I've just almost finished my tangential tool holder that's similar to your version. Actually it's cutting beautifully and I'm waiting for some black oxide solution to surface treat it before posting it here. Maybe one of those cutoff tool holders is next, but for now I'm loving making chips with my new tool holder. I'd heard that they were good but I didn't have a clue that they were this good and I've never made a chip before that was 3' long. Thanks for the inspiration.
I agree Crusty, a rear inverted parting tool is the best way for a small lathe. I can part off 2 inch M/S stock on power feed on my old SB lathe with that method using a carbide insert tool. Assuming that you can mount a rear toolpost on the lathe that you have.
So what's so new about that design for the parting tool, it was invented when Christ was an ankle-biter, it's been around for more than a century.
A simple google brings up quite a few of the exact same design.

Amazon were even selling this type of parting-off tool.

I've got mine converted to a QCTP so all I have to do is set the blade in a mount upside down and then it goes right on when I need it.
Hey Dan, if you don't have a tangential (diamond) tool holder you should look into buying or making one. I'm truly stunned by how well the one I just made cuts and the finish on aluminum and steel is the best I've ever seen from my lathe. I think a fella could upgrade from a collection of carbide tools with a few TTHs and be out of the insert buying market to boot.
Let's see - it's a tool (check) and it's home made (check), so it meets the fundamental tenet here and therefore is appropriate here.
