Here are a couple of pics of the new cart i am building, I used 2x2x.200 Aluminum angle for the frame and .100 aluminum sheet for the shelves.All the angle and sheet was cut in the wood shop on a 16" radial saw or 12" mitre saw,sheet was cut on a 10" table saw with 80 tpi blade. I made the tank brackets out of angle also and cut a half moon shape in them to hold the bottle. Used a new military strap with a spring loaded latch to hold the bottle.The tires i have had for years and figured i would use them someday.I used a piece of pipe for the axle and inserted a 5/8" bolt in each end and welded it to the axle to serve as a spindle, a locknut was used to hold the wheel on the spindle.Had to go to HF and get 2 casters for the front mine all mounted different and would not work.Some of the welds were to say the least difficult my nerves are gone due to disease and i am not as steady as i used to be but they all worked out and after a little bit of fine tuning everything is good.
I will post more pictures next week as this cart is long from done i have some interesting things to add next week.My old hospital cart from the earlier pics is now back to its original use short steel and clamps is what it's for.Hopefully i can get some welds that allow you to rest your arm and not be free hand.
