HERE IS THE QUESTION.

How would I approach the problem if I wanted to mount a 4" chuck on the 4"
table? With the 3" there is just enough room to tighten socket head bolts
to mount the plate to the table, but no clue how I would approach it except
maybe with 2 adaptor plates or with a spool shaped adaptor plate. I can
already see projects where I would like to have a 4" chuck on this table or
a similar one. There is no central taper in the table. If there was I
would have just bought a chuck with a taper on it already for the current
job.

(I am also working on a stepper mount design for this rotary table, but that
can come later. Right now I just need it to index a 3D part that needs to be
cut on 4 sides to remove all voids.)


Have a look at these:

On at least one of them there is a detailed description of someone
doing just that as well as a thread discussing it. I cannot remember
which one so a bit of search work may be necessary.
