32' Aluminum trailer

To answer one question invites other questions as far as doing it yourself. If you enjoy this type of work, can make a little cash, and learn something, in my mind yes. I would not use a torch on the aluminum (as it will just melt it) but a torch for the frame would be advantageous. As far as the type of torch, either one for acetylene or propane based on personal preference. I would recommend a quickie saw (demo saw and some call it a construction saw) with a metal cutting blade for the aluminum. Some cut use a grinder with a cutting blade, it just takes a little longer. Using a saw zaw would be expensive in the cost of blades. Good thing about aluminum, it does not spark so you can cut without fear of fire.
