I built a rear toolpost of my own (one big ugly lump of continuous cast
square CI bar) to accommodate a standard Iscar indexable carbide parting
off bar. It has a fence on it to ensure it gets aligned properly and I
can mount it in less than a minute.... As a result I'm never tempted to
try and part off from the front tool because "it'll take too long...."
This has led to an end of what could be a fairly traumatic time each
parting operation..... indeed for a while I was making short batch
production runs (200 or so at a time) of 6mm and 10mm stainless pillars
for the company I work for and during that time I've probably done more
manual parting operations than most ME's my age.... I'd recommend
indexable carbide to everyone for parting, the Kit-Q-Cut is a good tool
but the same thing can be sorted out for far less money by buying an
Iscar or Sandvik parting off bar and making the post to fit it.....
