Hey Lee
Yeah the vallder stuff is specifically for such application on gantries, they do have an X axis in production apparently but not yet released. So this type utilises 20mm rails and will take upto HG20 series carriages with 10mm t nuts.
Ignore the M12 comment they're for my L 90 series extrusion which incidentally is M14 I got mixed up, the gantry extrusion takes M10.

The rest of the plates are being machined on my other that's being replaced by this one I made years ago, the build of this one is on here somewhere. You can see how substantially made the extrusion is and size.
The concrete is mainly a dampening agent for harmonic reduction as the span and construction of this extrusion hasn't got that much deflection, I did consider the expanding epoxy based concrete but when factoring in the shipping and price/kg it was not worth it.
The Z axis I've gone through two iterations and had so many people having their own input, this is the first one that was based on Zee's design a little but when looking at the deflection it proved to be poor and such went back to one I've settled on in the renders above. I'm able to get full travel with maximum travel with both as the travel is only 80mm for this design and I tend to only do plate work and not anything mounted in vices.
Yeah it's a shame Zee never carried on with his posts, enjoyed following his mad ideas.
