Yeah i want to build a plasma table as well. looking at building it to have a cut area of 8ft by 4ft ( a full sheet size). I was told that i should be looking at a making it move at around 350-400ipm. What do you think? Also was thinking of using stainless steel pipe as rails then making up a truck with plain normal old bearings set out at 120 degrees apart, ie a triangle. Whould this be accurate enough for plasma cutting. Was also told that rack and pinion would be the best way to gain 350-400ipm speeds. Any thoughts, lets us know. We could work together to make life easier maybe.
I plan on trying to make a business on the side, offering a cutting service to engineering and fabrication shops around town. how do u think i would go.
