If you don't mind, could you please list what components you bought for your lathe motor? I'm rebuilding an early cast iron unimat that doesn't have a motor and I get a little bewildered when it comes to what electrical components I need.

For starters a DC motor, i have the 24V, 150W, ZY6812
Got it from a UK ebay seller of e scooter parts
A DC 24v minimum 200 watt powersuply.
And a PWM - 12V~40V 10A DC Motor Speed Control
For the PWM there are some more options like wirh the integrated RPM counter (have to install the sensor somewhere for that.)

These are the specific bits I'm using on my Unimat SL:
- 24v 120w ZY6812 Motor
- 24v 15A 360W PSU
- 9-60v 20A PWM speed controller

Working on a stage/storage unit for my Unimat - the idea is to make the setup a bit more portable, so that means inlays in the drawers to stop stuff rattling around, and hopefully not vibrate when the thing is in use.


Left drawer layout on inlay board, prior to drilling & cutting out:




Layout for right drawer, unfortunately I destroyed the plywood inlay while cutting it out with a jigsaw ...




... which is not surprising when you look at the template I made for my 2nd attempt in styrene:




THings continue to go wrong, here I've made the inlay upside down so have had to glue an extra "top" panel to get trimmed right down later:

Finished ... I'm not sure about the rubber isolators the Unimat is sitting on, I'll just have to try it & see. I may end up screwing it down directly to the top (more stiffness, but more vibration). Interior of drawers is clearly the idealised version - they'll end up getting filled & untidy with allen keys, impromtu tooling/spacers, more cutters, swarf etc etc. Colour is a mixture of "teal" self adhesive felt & home mixed Tamiya X/XF acylics airbrushed on - not too bad a match considering I didn't have the felt in front of me at the time of mixing, just a photo on the eBay listing.

Things I would do differently:
- definitely make it a bit taller, even an extra 10mm would have made it so much easier on my knuckles when doing the machine screws up;
- have lower sides/back on the drawers to clear the machine screws without notching the drawers
