New build help needed

[arg123]

Following Dean's drawings I finalized the base design, so any comments and corrections before I start cutting would be appreciated.

Blue steel (top rails) is 80 x 80 x 5.
Red steel is 60 x 60 x 5.
Green steel is 60 x 60 x 3. (trying to save on weight).

Top rails would be bolted to the supports for alignment purposes and use epoxy putty(later I would need some more details on that) and then epoxy leveling. Final length of the top rails (overhang) to be decided along the process.

What height from ground to top rails is recommended?

I ordered a straight edge 2000mm DIN 874/2 from same place Boyan did, thank you Boyan for posting the link,
and I also have a precision level 0.02mm/m so I hope I will have a quite true reference plane to start.

Thank you

Now don't go blaming me I had nothing to do with it. . .

No fixed height really but the machine I showed is 950mm. Work out the height you want the bed and how much clearence you need and you'll get to the figure you need.

The height of the bed will come down to ergonomics. The higher it is the more difficult it will be to load heavy material onto. As the same time, too low will make changing the cutters a bit difficult.

My preference would be to make the bed around desk height. The Americans say a typical desk height is 29" so 1metre would be just about right.
