Hi Sean
I once bought a 2A a long time ago, disassembled in a few assemblys. However, I never set it back together and made a replacement for the missing gib of the z-axis.
But if you need some close-up pictures or some pictures of a probably missing part, I could make you some.
I have attached a picture of my machine (also got a few accessories like a milling arbor, several disc cutters, a vice which is though not originally from centec, rather chinese)
I want to assemble the machine in the more or less distant future. I also thought about converting the cross slide to metric acme screws since I am used to the metric system. The scales are not working anymore but I actually am not so much into using such "modern" scales on this machine. Somehow I think that this does not fit really much on an old machine like this. (But thats only my personal taste!)
Cheers Florian
