I built a quick Jig with a sheet of particle board and some offcuts of framing pine then proceeded to turn about AU$2800 of 100x100 x 3mm, 100 x 50 x3mm and a couple of lengths of flat bar into These frames

Then spaced them out to about 1m centres

and then started on the gantry, here it shows missing some bracing.

Atop of the posts of the base frame sits two 4m lengths of 80x80 tslot extrusion, which i intend to mount my rack and rail something like this

I will be making up some form of guarding to cover,although i do intend to build a room around the router once complete and the machining of the wax will produce no dust.

After some extra bracing it was time for some 2k urethane, I wanted to finish as much as i could as i went to minimize the times the gantry had to be lifted on and off.
The posts have now been filled with sand to minimize vibrations, it has made a huge difference.
