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.

There is one inner brace already - 15mm plate & then 20mm outer on the end.

I'll look at doubling up that inner brace later.

I have to keep an eye on the cost as its already adding up to way more than I originally intended...& its going to take me months & months to sort out the finances for it - so yes, the budget is important. I appreciate that its not worth cutting some corners - but I can't shove a bottomless pit of funds at it.
