I recently became a watchmaking student, and I can't afford a watchmaker's lathe and all the collets that you need to really do anything.
This doesn't normally matter though- I have my own school lathe.

I did, however, a while back invest in my Taig mill with 18" X travel, and I just remembered that Taig actually makes a WW
spindle for watchmaker's WW 8mm collets, complete with drawbar, for only around $104.

I was well outfitted with the mill before I came to school, and tuition and other costs have limited my tool budget to very little. I was
thinking of buying just the WW spindle, and mounting it on my X axis, and BAM! Instant precision watchmaker's lathe.

I'm still trying to work out how I remount my motor for this, but I know I can put a toolholder on my Z axis, and use my X and Y axes
to move the whole "lathe" as a giant crossslide. I will of course need to account for the non-metric leadscrews, but I measure everything anyway.

I was wondering- who else uses the Taig WW spindle, and what do you think of it? Is the runout worse than decent wet spindle standard setup
American style watchmaker's lathe?

Do Starret WW collets and others fit well? I'm already aware that not all WW collets are made to the actual 8mm they are supposed to be,
so I was sick of looking for old collets at marts, and just going to buy Starret collets or whatever I can find cheap as I go.

I use a semi-decent Chinese made to DIN specs Geneva/Swiss style canitlevered bed Vector lathe in class, but I need something at home
to get real work done until I can get enough money to buy a proper full American setup.

Any thoughts? Is it worth it, or don't bother? I am already turning to +/- 0.02~0.01mm reliably on the Chinese lathe.

Can the Taig spindle match that?
