G'day John.
You've given me an idea how to machine the tool holder and the packer.
I need to think about what radius is required and whether the lathe
could cut it. If the concavity in the tool holder can be cut by
mounting it on the face plate and so can the convex surface on the
packer/s. The standard tool holder with the tol mounted on the
outside could cut the radius.
I will explore the idea of using a commercial rounded section, I am
sure I have seen something like it in brass; used for trimming
comings on boats and for carpet edging.
In that the Micro Mark rocking tool holder costs USD26.20 and a
standard tool holder costs USD10.95 it may not be worth the time and
effort to just to save USD15.25.
It must be remembered that the rocking holder does not totally
obviate the need for shimming but it makes it much less critical.
Ellis's comments about increasing the clearance should be noted.
I am sure I have seen a tool post with the rocking packer straight on
the flat floor of the tool holder slot.
One good turn deserves another.
Regards,
Ian
