Ok - V2...

Inner end pieces are 15mm plate
Outer end plates are 20mm
bearing blocks also beefed to 20mm
Front plate is still 5mm - more to keep crap away from the leadscrew than perform a major structural role...although should help with twist & sideways flex.
Rear stell plate removed - although that was there more for a convenient flat mounting surface rather than anything majorly structural.

Still comes in under £100 - so that keeps me happy

Better but still no inner triangle brace.!! See pic of brace on my machine. It's only a small thing but does help stiffen and dampen vibration more than it looks.

Don't let Money run this Build too much because you could easily find you spoil it for not much more money.!! . . . Better waiting and saving up to do it right than skimp. It's a lot of work building a CNC machine and just small things that don't cost the earth can make a big difference.
