So I will not have a "tool table". That's a nonstarter.   I don't 
provide bits, people will use whatever they like (a very large range!) 
and the CAM stage is their business, not a machine issue.  I wouldn't 
require them to mod out the tooltable file to match their bits, nor 
would I even allow it.

I don't see what purpose a tool table serves here.  T1 could be a 1/8" 
with 1.5" past the nut, or a 1/4" 3" long.  The machine's never going to 
do radius compensation, the CAM stage is what accommodates the cutter 
dia.  Been standard for a very long time to do that.  The bit length 
won't matter because it's manually zeroed, making zero either the top of 
the stock or the bottom (depends on datum choice).

Collar bits won't be used much at all.  When they are, you could say 
"The z-axis was zeroed with the T1 3" outside-the-nut bit's tip, now 
we're switching to T2 which is only 1.5" outside-the-nut" and adjust 
automatically.  But that will NEVER happen.  We don't use collar bits 
often and it's not a simple thing to have new users set up.  They'll 
just have to zero for the second bit.
