Misumi USA appears to be great and happy to deal with small orders.
Misumi near Australia (I think Singapore) only want to deal with businesses.

That's ridiculous overkill and a complete waste of money. I've built many machines this size and larger using 45x90 using the "L" design gantry and they are plenty strong enough for a machine this size. You'll get away with a much smaller profile and 80 x 120 would still be massive overkill for a machine this size.

Maybe I could drop the whole build back to using only HD 45 extrusion?( 45 x 90 for the sides and gantry.)
Would be alot cheaper and there are a lot more size options...... as long as it would stiff enough.
Can do some simulations in Fusion I guess.
I am a little concerned about attaching 45 extrusion to side plates using just the 2 holes in the centre. That does not seem the best idea.
Is there any way to utilise the square hole in each corner?

You don't seem to believe what I'm saying to you regards the strength so this will be my last post on this subject because I'm clearly not getting thru so not wasting any more time saying it. However here's the answer to your worrys regards bolts, which by the way are 12mm with a holding force more than enough, even without the pockets.

Sorry Jazz....Just lots of things to think about and my goal posts keep on moving....
I remember you mentioning that now.
It just that Extrusion is crazy expensive here and if the basic foundations are wrong, it carries all the way through the machine.
