Zero rake lathe tool holders are not common here and very difficult to

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.

I had problems with chatter on the 7" AAMCO, so I took the advice in a
Brit shaper text and built one that put the tool bit behind the
clapper pivot plane. It had come with Armstrong-style tool holders,
just lathe lantern-style ones. No more problems after I made that,
just a nice "shoop-shoop" when cutting. Williams used to have a tool
shaper holder cataloged that would let the user put the bit at any
angle. I kind of copied that when I couldn't find the real deal on
the shelf for less than $200. Just used a rectangular section of hot-
rolled strip for the shank that the tool post held and made up a
sleeve that got welded on the end. Back end of the sleeve was behind
the clapper pivot. I took a fine thread 5/8" bolt, turned the head
round and drilled and filed a square hole in it next to the head to
fit a 1/4" bit. A nut and washer made up the rest. Filing the hole
took the longest time on the project, finished it all in an afternoon.

And a shaper without a vise is kind of like a car without tires, very
limited. Hope the shaper was bought cheap. I suppose a guy could make
one up from a regular mill vise with some sort of adapter plate and
shank for the pivot, probably wouldn't be as rigid as the real deal.
