I recently made a cutoff tool holder for my lathe. I got the idea for it from Winkys Workshop on YouTube and did a few small modifications and it works quite well. I had your typical holder that goes in the quick change tool post and I have always had limited success when parting off. My lathe is a 12x36 Enco, so not a mini lathe but certainly not rigid enough like the big boys.
This holder does take the overhung load off the compound and makes it much more rigid, which results in much better control when parting off or grooving. I made this from 1-1/2” square 1018 and used a 1/8”x11/16” cutoff blade. One operation that I didn’t show, is cutting the 1/32” slit through the body to it’s full depth. When I was taking the picture, I only had a 3” diameter slitting saw blade and had to order a 4” diameter to finish slitting it deep enough, so it clamps the blade properly.
I would suggest watching Winkys video as he does a great job explaining things, much better than I am capable of doing. The only change or addition that I made, was to add two blade clamping bolts to secure the blade, rather then rely on the tool post bolt to hold it. I have made several cuts in some 4140 shafting and had good results. I had my RPM at 60 and hand fed the cross slide, not brave enough for power feed yet.
I also had a trail mower in my shop that I designed and built for my Son-in-law about 10 years ago. Doing some yearly maintenance on it for him. He pulls it behind a 4 wheeler and it makes a 60” cut, his trails look pretty good.
