Im looking to make a mobile base for my new saw and motor. the saw is estimated around 1000 pounds, and the motor I would say is over 120 but less than 200 pounds. I have 7 casters rated at 350 pounds each. Locally I can get some tubing, round and square. I have no idea what kinda of design or material sizes would be needed for this weight. I can get 1x1x1/8'' square tubing for relatively cheap, but I dont know if it would be strong enough for this use?
