Seeing so many combination machines I just had to modify my 5' x 10' plasma table to do some routing. One design by PlasmaRouter appears to have a 6-8" tall gantry beam, not sure how deep.
PlasmaRoute CNC - CNC Router Table
Bought 2040 (2"x4") 80/20 beams 74.5" long for the plasma table and they doubled my order by mistake, told me it was a Christmas present.
I could stack one atop the other and have a 'L' gantry beam 6" tall and 4" deep approximately 6' long. IS this sufficient to resist bending or vibrating in routing wood? Video of their machines in action appeared to cut raised panel chamfers in oak resulting in a fine finish. My use will mostly be in soft woods, but it would be nice.....
The Mechmate has two parallel frame members riding low on the long rail axis with the router slung low and between them. That looked solid and potentially vibration free.
My question is will my 2x4 beam be enough in itself, or will the two of them be required to stop vibration and beam bending? Or should I go beefier yet?
Thanks,
