Parting on the Lathe

[Mayhem]

I've had good results on my friends 9" lathe using parting blades made from old carbide tipped circular saw blades. Cut them out with the plasma and then touch the tips up with a diamond file and they work well in the standard parting holder that came with is 100 series (AXA) QCTP. The problem is (as already noted) when you have to adjust the length, as height also changes.

I have two double ended Valenite VH101-32-3 parting blades that I bought (very cheaply) from Ken. I cannot recall the inserts these use right now (I'm sure Ken will though). We spent some time looking for the VGTB 16-25 tool holder, which Ken managed to track down for me for a good price.

Ken more recently gifted me a VG112 R 16-30 Parting/Deep Grooving Holder that takes VTG double ended inserts. This is my go to tool for parting hollow or small diameter stuff.

My friend in envious of these but it is proving difficult to find a similar system with a 1/2" shank for a reasonable price.
