if you check the specifications it will tell you what size tool holder to use For a 9A I would use a axa

James, I tried to figure out those Diamond tangential tool
holders. The manufacturer lists the sizes based on tool
height in mm and none of them make any sense to me. How did
you figure which size holder was good for your South Bend 9A
and Which was was good
for your 12" Atlas??





I want to order one for each of my machines, but I am
stumped by the Australian website. Please, help.?

I have an
AXA on mine and on my South Bend 9A as well so I can
appreciate you wanting to share holders and tooling between
lathes as that is what I do as well.? My larger lathe is a
South Bend 16 so I use a CXA post and
holders on it.? It is close to the border between using a
CA or a CXA.? I went CXA as I don't tend to hog out
things on the lathe and the price difference between CA and
CXA set and holders is huge!? I have a few friends who have
Atlas lathes, one has a BXA
and loves it, the others have AXA sets so I can't help
you with an informed opinion.? I think I've used my
rocker post twice in the last 11 years.



As far as
the tangential tool holders that were mentioned above, they
are my go to bit holder for all my lathes.? I have made one
for my Atlas 618, I bought a Diamond set and a pair Wimberly
holders for my 12" and 9A and
have been making a set for my South Bend 16 that will take
either a 3/8" or 1/2" square tool bit.? I may buy
a Diamond 20 set for the SB16 depending upon how my shopmade
versions turn out.? Wimberly doesn't offer a holder for
my 16" lathe.

Jody,
?
A number of problems.?
The lantern tool post is centered on the compound, so the
forces during cutting are straight down, as opposed to using
a QCTP when the tool is hung? far from the centerline of
the tool post. Second, you would need
to duplicate the high positive rake of a tool like it is
when you are using a lantern tool holder, but, if you were
to grind a HSS tool with the same geometry and hold it in a
QCTP, it will be much better.? I do not have a tangential
(diamond) tool holder,
but that should give you good result, but I still feel a
lantern toolholder is still a much more rigid setup, but not
convenient.

Kurt,

What if you used that
same HSS roughing tool in the QCTP???


?


Are others finding that
large cuts on hard steel are more difficult with QCTP.? I
haven't had experience with both in doing large
cuts.

I have an AXA from CDCO,
and love it. I will say do not get rid of the lantern tool
post if you have one though. The more I use my old machines,
the more I realize they are best used how they were
intended. I was roughing in a part yesterday
of 12L14, and with a nice sharp HSS roughing tool, can
easily take a 0.050 deep (0.100 on the diameter) with very
little strain on my lathe. Even with W-1 I can take at 0.030
deep cut. Now I use my QCTP, it's not going anywhere,
and you cant beat the convenience,
just saying, they tear off the material instead of cutting
it. The old guys knew what they were talking
about.

I want to switch QC tool
posts for something I can easily find extra holders. Looking
at the Aloris fit chart an AXA is called out for all Atlas
lathes. It looks like a BXA would also fit. What size are
you using with your 12" Atlas.
I'm leaning toward the BXA because I could also
transfer this tooling to my 13" lathe later. My only
concern is the bulk of the tooling limiting getting close
the tailstock. I am currently using surplus mini lathe
tooling with the post measuring 2.5 x 2.5"
with a spacer on the bottom. Thanks in advance for your
input.
