Hezz,

I see in your render you kept the area small between the two blocks. May I ask the reason?

Small progress on the design. The plate of the carriage is 10mm thick steel. Is it thin for the machine? Maybe 15mm?

By the way, the plate will be longer because the rails will be mounted to it.

In my render I do not show the rails. The narrow steel section was just a method for doing a tailstock tensioner which would be between the rails.

I was just being lazy. The render show a surface mount tailstock tensioning plate.

Edit: here is the modified render. The central section between the rails is just for the tailstock tensioner. But is surface mounted into the EG.
There are gaps under the edges to allow a clamp to run under them.

I also did some design work for a hybrid manual/CNC lathe that I might build in the future. Here is the render and in a way it might be similar to what you are working towards.
