Ok took a few pictures of the progress.



Now comes the fitting of the motor assembly and X Twin Ballscrews...Hmmm Im sure that will be fun, it took me long enough to get the frame parallel..

Ive now reduced the Z to 250mm Max and reduced the gantry mass considerably. Im hoping to have the screws/ motors mounted and close to test by tomorrow evening, But i cannot do any tests antil i recieve the two pulleys and belt to connect the steppers together as a precaution against single motor failure twisting the gantry. Im also looking for a source of 1.6mm 8x4 sheet steel, but the delivery costs are more money than the steel itself... Grrrrr

Rick If those pieces that look like 1" box are for the bed support then it's not going to strong enough with big chance you'll get bed dipping.
The forces when plunging and ramping etc can be high.! Even my 50mm box with 16mm Ali bed can flex when plunging into hard materials. Honestly don't under estimate the forces.!!

Hi Jazz, that 1" box is going to be supporting the water bed for the plasma only. The milling bed is going to be much tougher and stiffer. There is a 50x50x3mm box section frame topped by 40x40 profile for the Router/Mill bed that is still in production, you should see that appear about mid march.
