Thanks pcstru,

I already spotted your post above which I read with great interest. The early Z-stop bump would have worried me but I am very impressed that you had the machine up and running in a day. I'm afraid my project has a very long way to go before I get round to ordering any hardware but your information is already proving useful. I had noted the relatively shallow T slot panels from the Heiz site which you confirm really need to be supported in tthe middle (presumably across the shorter dimension). I would be working on deeper jobs so would need extension pieces to drop the bed lower (to allow for the rotary table plus a bit of workpiece upstand). Heiz mention a Z-extender kit but I have found no specific details of it as yet.

Look forward to seeing your pictures.

All the best

Davem
