As I want to be able to make light cuts in steel I have redesigned the machine to make use of the some of the rails from my current router and I have purchased a set of thompson THK style rails as well.
This gives me 25mm rails for X, 20mm rails for Y and 12mm rails for Z.
I have also changed the layout to a wide desktop style as this will sit in position better and makes for a more compact layout.
The design is 99% finished and I have started to machine the ballscrews (very slow going on my 7x12 but I am getting a nice finish).
