Even though this is not a high precision operation, I'm having trouble figuring how I would reposition the work in 3 dimensions and keep it seamlessly matched up with the part it cut on the previous run. It seems like a helluva problem, almost suggesting I should give up on the Taig and work with new hardware that could handle the full 32" length of the stock. The cost involved in that might be excessive though.

Make a 32" headstock/tailstock pair on a flat bar with holes bored every
(table length minus a few inches) and put a pin on one end of the
table. Put a hold-down screw in the middle and a pin on the other end
of the table (table length minus a few inches) from the first pin. As
you finish one section, you move the whole thing most of one table
length with very definite stops and accurate location.

Of course a bigger table would be nice, but some of us can make do like
this.

So if the holes are 10" apart, a 30" piece takes three passes to machine
with two moves.
