ID:	1301 I made this tank cart last year for lobster mini season. I can put 8 tanks in it and roll it almost anywhere. The frame work that holds the tanks is 1/2" conduit bent and brassed together, the deck is 1/8" aluminum diamond plate welded to 1 1/8" x 1/8" aluminum angle. The main frame 1"x 1 1/2" steel square tubing. The wheels are from HF and are mounted on 5/8" steel rod. Having the wheels under the deck allows them to turn sharply. This makes for easy manuvering on the dock or in the parking lot.If you have ever luged a dozen tanks back and forth, at the end of July in Florida, you know how handy this thing can be.
