You are correct as always ;) but I think the smaller 80x40 was okay strength wise, just alot more handy with the 90x45 because of the bearings and the clever bolt on approach

After some sleepless nights watching some video tutorials about Fusion 360 CliveS point me, thanks Clive, I came up with this.
The questions now are:
Can I use two pieces from this aluminum extrusion for the Y axis, not complete on the photo, and screw them them at left and right on the supports?
And what extrusions can I use for the X(long) axis, to support the Hiwin rails and screws.

I was thinking the option of using aluminum extrusions for the axis, since this way there is no need for drilling ,tapping and leveling with epoxy!
Yes use two pieces one flat and one upright like an L. Then drill the upright one down the channel slot and bolt it to the flat one with tee nuts M6 90mm cap headQuote:

Thanks Clive, always so helpful!
Can I use the same extrusion for the x(long axis ) to bolt 20mm rails and ballscrew on? Or I need a thicker extrusion?
Its very nice using extrusion (heavy duty) because the slots it the 90x45 are exactly correct for the bk and bf bearings and can be mounted with tee nuts 6MM the 20mm rails will also mount into on top of the slots. You would have to work out how to fix the extrusion to your frame.
The ends of the extrusion can also be tapped without drilling for M12 bolts. with a spiral tap in an electric drill.
I see that they are not as cheap as steel tubing but that save me from a lot of work and time!
Thank you Sir!
I will message the seller,Thanks!
One more silly question..For X (long axe) what side is better the extrusion lay on the bed side, the sort(45) or the thick(90), for matter of stability.
