Would it not be OK to just grind the toolbit, taking into account the
built in angle of a typical lathe tool holder, so the end result is the
same as with a zero rake type?

As an aside, but slightly related (because it has zero rake): I was
having trouble making a slot, until I tried a lathe's parting tool
holder, which also had a gooseneck feature. It changed from making the
shaping job a nasty ripply finish, to cutting smoothly as silk.

Shaper tyro.


Not a problem to grind the tool , ,it's just me , I just like to have
the tools to suit the machine . Toolaholic .

I have read that the gooseneck tool holders are good for preventing
chatter .
Also it depends on whether the cutting edge is in front of the clapper
pivot point or behind .
The Armstong universal tool holder can be set either way.
It takes some experimenting to see which give better results .
Haven't got to the slotting tools yet.
The shaper is still in bits and it will be a while before it's actually
running , Im being proactive and looking for bits so when it is ready to
run I have the stuff at the ready.
