Im a sheetmetal guy but the army thinks im a machinist. I agreed to use my newly purchased bridgeport to mill some aluminum tubing that will be used as spreader bars for rigging helicopters or components inside of cargo jets. The ends of the 3" aluminum tube get holes and relief to make way for the chains. I dont own an incredible amount of tooling and this project has a deadline. I would very much appreciate advice for clamping to my table and an appropriate cutter. Its 1/4 wall 6061 al.
