>On the subject of lubrication, does anyone know where I can buy a sensible quantity of synthetic semi-fluid grease please?

My mini-mill has no practical way to get oil to the ball-nuts or the bearings riding on the supported rails, instead I lift the rubber skirts every once in a while and squirt a load of a TF2 Teflon oil onto the shiny bits:

No doubt this isn't the done thing, but having done it for five or so years, I'll probably keep doing it. There's logic for ya.

Nice build BTW.
