Course head adjustment by big hand wheel, fine feed by the smaller one.

Its built from an SIP Inspection Microscope. Needs a little finishing, but the important bits are done.
The travels are 2 inches by 3 inches, but with 0.00005" verynears.
Ideal for small parts like the helicopter bits I make.

I happen to have a T slotted table lying around thats the correct size:

Think thats going to work.

I might replace the chuck with ER16 collets, as I have a full set of them, and they should have less runout.

The ways have no play in them, they use a pair of opposed V's with bearings running in them. Very nicely built.

Sweet, I like the smaller precision stuff as well. But it seem's the nicer tools cost alot more then the same thing in monster size.

I would have been tempted to bring that with me. I'm sure it would have fit in the overhead luggage compartment. :D
