8x4 router build. Steel base & Aluminium gantry gantry

[D-man]

Is this to make it more rigid..? From the commercial ones ive seen they are all mounted like this. as i thought with it being the Hiwin rails with less play than the SBR stuff

I dont suppose anyone knows what this bar is for on the bottom of the gantry of the Techno machines do they? Im guessing that when its tightened it pulls it square of some sort?

Nevermind ive found ou what it is

"a special steel backing beam and torsion bar are integrated into the axis for added stability. The torsion bar acts like a sway bar on a vehicle, which in turn keeps everything straight and taut when cutting loads change. The steel backing beam provides extra support to the linear rails, greatly improving the router's rigidity."

Hi D man
I would wait for conformation off one of our more experienced members but i would think the Z needs to be on the other side of the gantry so it is better centered over the X axis bearing blocks.

Yeah ive been thing about this myself, The setup works on my 4x4, however thats only cuttin MDF and light plastic. i have been toying with the itea of vertical ones on this one, but the side to side motion worries me as im not connecting the gantry under the table.
