I am making a box way(rectangular section flat slideways) lathe.It is being made with 2 pieces of 1"x1/2" flat MS stock seperated by 1/2 inch in the middle. This is mounted onto a piece of 2"x3/8" with a 5/8"x3/16" packer between them.
The 1/2 inch wide slot will create a good length to width ratio to keep things in alignment.
The whole assembly can be twisted and biased to get the required results. There will be some lapping required.This I intend to mount to a steel box section with adjustable mount points.The final assemble will be primarily mounted on the 2 airy points with extra support as required.
It is my long term project over the coming winter.
Nick have you read the Gingery books ? He has some great techniques that may come in handy. I appreciate that you know what you are doing but Gingery may have a few ideas for you.

The other outstanding book is Machine Tool Reconditioning by Connelly. I don't have it but many I respect have nothing but praise for his work.

Thanks for the links. The reason for the fab approach to the bed/rail assembly is that I can get a much better length to width ratio on a relatively short distance for the tailstock, steadies, and carriage assembly. Also having a T type slot down the middle of the two rails allows for a center vertical clamp of the tail stock a steady rests.Not sure of the name for them, but intend to use the 1/4 turn nuts that rotate and have a flat that becomes parallel to the underside of the rail.I think they are Rhomboid T nuts. Another feature I want to incorporate is air floating bed like is used in some CMM's, raises the assembly by about .01 or so off the bed and glides along.It will also help to keep wood dust etc out from around the slides of the saddle.
