You spin me right round

I dropped in at CNC and Cupcake World and got myself six ball bearings to hold the threaded rods. I now proudly own:
  • 3 x 6201-2RS: dual-rubber-sealed, radial, deep-groove, self-lubricating ball bearings. ID=12mm (ie, M12), OD=32mm, W=10mm. Grease lubricated.

  • 3 x 5201-2RS: dual-rubber-sealed, double-row, self-lubricating, angular contact ball bearing. ID=12mm, OD=32mm, W=15.9mm.

...all I know is that to me
you look like you're lots of fun,
open up your lovin' arms,
watch out, here I come.
You spin me right round, baby, right round...

Originally, I though I'd use 2 x 6201 at one end of the threaded rod, but the recommendation was to use a single 5201 instead. We'll see how it all works out.

I'm now locked in to using M12 threaded rods and a 3-axis design. I'm getting close ! I need to decide on and order stepper motors and drivers, draft a general router table design, buy the building materials and get going. If only I wouldn't have to do various autumn chores around house and garden...
