You might consider building a lightweight sub-table and just move that.

I have looked at some gearing diagrams of gear hobbers and I noticed that a
'differential' gear set was included. What does that actually do? I suspect it
is for cutting prime number gears?

of such a machine?

Found a really nice up / down counter on EBAY. Works immediately with single

negative numbers... It does! Has five digit display, four digits when counting
