Hi All,

Just wanted to start a thread following the design and build of my second aluminium gantry router.
I currently have a 2' x 4' all aluminium router based on THK type rails and ballscrews. This was built just for the building rather than a specific reason.
I have never really found a reason to cut anything bigger than 12" square so this machine is really overkill.

I plan on building (and have started to collect parts for) a smaller much heavier duty router with a decent spindle that will be for wood, plastics and aluminium but be capable of light cuts in mild steel.

The frame and gantry support will be based on some aluminium profile I have got hold of (this is 66mm sq and very heavy duty). the Gantry side support will hopefully be 16mm Aluminium plate and all other parts will be 10mm plate.
The XYZ rails with be fully supported linear shaft 20mm,16mm,12mm respectively.
Screws will all be 16mm 5mm lead ballscrews which I will turn down as required.

I will jopefully have a 20mm T Slot table but we'll see.

Cutting area should be 475mm x 300mm x 150mm
