I was using an aloris cutoff tool holder with a quality tapered cutoff blade. I have ground a slight concavity on the top to curl the chip. It works well except for the last 1/4 inch or so. It stoped cutting and forces the entire WCTP to pivot.
This was hand feeding and it felt like I had jammed the tool block into the work. It pivoted the setup so the blade was pointed to the headstock enough to be noticeable. Then I guess it was just dragging andburnishing the left side of the groove. I even widened the groove to two blade widths for clearance and got the same thing just a bigger angle before it jammed.
I did not want to tighten the toolblock nut anymore then I had. it was a lot tighter then i normally do it up.
I know parting off can be difficult just wondering what folks recommend. I finished with a hacksaw in the lathe. This was toolsteel cutting with HSS. The chips rolled up nicely and were not jamming. It was cutting nice for the first 3/4 of the cut
