That's a closeup showing the gantry. It’s 80 x 40. The side rails are 80 x 20. I altered the stock z axis because it sucked. The replacement is similar to what is used on the Workbee.

I’ve already ordered a water cooled spindle and VFD to test. I’m probably going to replace the gantry before fitting the new spindle though. Might see if I can make the plates for the new machine with my old machine.

What advice I do need is to do with what linear rails and ballscrews to go with.
