I'm wanting to make a cross slide for a CNC lathe conversion similar to OmniTurn units. The basic idea is to mount THK linear rails on steel flat stock to make a cross slide. I have questions within questions in parenthesis. Would I be better off to buy (CRS or HRS?) and have it ground (Blanchard?)? Or would it be better to buy ground stock (toolsteel?)?
Thanks!

Roger,
I have OmniTurn slides on a Hardinge lathe. Can't help you with the type of steel, but I can give you rough dimensions of the major components if that helps.
You may want to subscribe to the Yahoo Group: DIY-CNC "This group is for those who wish to explore the design, construction, and use of homemade, or home retrofitted CNC machines."

Theres also cnczone.com which has people who retrofit or build from scratch.
Do you need to machine the stock? If so and you can mill it yourself, I would use CRS. But it tends to wrap when machined. Stress-reliefing it before and paying attention where and how you mill it helps.
Best would be having a CI stock.

How do you like it so far?
