2. Way oil.
4. Stains. Cutting compound, do you really wanna get that deep?, wd40 works great for rust stains too.

thanks lee. Was hoping for some kind of chemical, ive tried soaking in wd40 for 24 hours, scrubbing, if it means using cutting paste, I think il leave the stains there.

ordered a couple of servo's for x & y

intend to use a standard nema 23 4nm stepper for the quill (x)

The spindle, is intended to be driven by a "vari-drive" pulley. This is essentially two discs, that are wound apart (by spindle speed winder)

This picture shows the spindle pulley (with the top cover removed) here you can see the two discs


a hand-wheel mechanism essentially parts the two discs, effecting where abouts on the diameter of these discs the belt grips, which in-turn changes the drive speed of the spindle



problem is, I dont have the corresponding (sprung) pulley for the motor (or a motor for that matter at this point) I need something like this



the pulley itself is NOT cheap. new, as a set of parts about (£300). As I intend to drive a motor via vfd I may just scrap this mechanism? thoughts?

below this, there is a back-gear, that I can still utilise even if I remove the variable disc arrangement and replace with flat pulleys?


FYI, if anybody is interested, I note the seller has another one for sale.
