I recently ordered a oliver 25 inch planer and in my current shop I need it to be mobile. I can't find a mobile base rated for the weight of the machine (apox 1800#). I have a shop fox base that I believe is rated for 1500# under my shaper (powermatic ts29 1100#) that is very difficult to move. Is there any option out there for a heavier base? Am I better off to have a local welder make me one? If I have one made is there a certain kind of caster that would be best? I seem to prefer the urethane coated cast iron casters on my other bases l.
