As you can see, I do not know how to get "deep links" on Brick Shelf. If I
figure it out I will post the links again.
The tools can ride a disk in front of Z and move in when Z is at a tool
change height. The disk moves in and Z can discharge the old tool. The drum
rotates to the new tool and Z picks it up and settles down to Home position.
Z does most of the work. You need to rotate the disk and slide it in and out
under the spindle.

This is a really ambitious idea. I think you will lose your Lego Purist
thinking trying to cut plastic with plastic. I hope the newer gears lend
themselves better to anti- backlash designs than the old gears. You best
design your positioning device driven from the slide and not the drive gear
train.

Oh! It will flex!

Soap! Never thought of that! Sounds like it would really work. Hmm! Hot
water coolant!
