It looks like you should remake the sides of your gantry to make them longer on the underside of your table frame. You could then add front and back plates made from wood or metal to stiffen the assembly up even more. A torsion box assembly would probably make it even stiffer than just the front and back support pieces.
See Joe's CNC Model 2006 gantry for inspiration:

If you're going to remake the gantry, now's the time. I hope the suggestions give you the help you were looking for. |
