New Plasma build in OZ

What shoud I be targeting for the gantry weight?

Assuming 2100mm wide ganrty with a air scribe
Im comming in just over 50Kg now but some redesign still to do.
That weight includes everything that moves right down to the wiring and torch.

I tend to keep it under 25Kg. Alu everything.

Thanks Tommy

Im assuming thats everything that moves on the X and Y axis

Everything that moves, here have a look:

Had some time to work on the design.
Any comments or ideas would be very welcome
 

This is the water table with the water removed, at cutting height and overflowing. I have put a gutter around the cutting area to cach any spills and splashes.
