That is on the list as well as some bed sides. I have the expanded metal for the "headache" rack already in the garage. I actually have a full 4'X8' sheet of it and was thinking about making the bed sides as well as back window protection all from the same stuff. Need to buy some square tube for the framework I guess.
Out of that sheet I could make two 15" total height bed side rails and a full back glass protection. Just need to figure out how much square tube and angle I need for the framework.
Would LOVE to use all square tube..... but the cost gets to be a lot quick!
The trick to cheap metal is knowing someone that works at a place that orders large quantities... I got lots of 1" (about 50') and 1/2" (about 40') sq. tube for 50 bucks since my dad works at place that basically fabricates/assembles a bunch of stuff from plastic to metal. They came in 20 ft lengths, which I handed dad the tape measure, soapstone, and the Hitachi G12SR grinder with a cutoff wheel, and he brought it to work, cut them down into 8ft lengths, and hauled them home. I will be using most, close to all of the steel in a welding cart that I am going to make... lol, it's fricking huge, all for a little Handler 140...
But I'm thinking ahead, like what if I started a fab business, or my own auto shop, etc and run through crap tons of wire...
I could (probably will) rig up a 33lb spool holder, and run a tank to do MIG welds or gas shielded flux core, or just do self shielded flux core. There will be a spot for the largest tank of argon that's available, and the handle will be a part that holds the tank on. The handle will bolt on, and will be easy to remove. Them damn chains don't do it for me... I don't trust the thin links that they use, and not to mention how most (well, all) don't even go up above the middle point of the tank, where it should be, supported by a lower chain just below the middle point of the tank.
It will roll on all swivel casters (I hate not being able to slide a cart in between a shelf and a tool box...) The third shelf will be about 5" from the bottom of the cart, and will likely hold leftover useful shorter pieces of steel, while the upper two shelves will hold the helmet, gloves, etc.
I plan on ordering more stuff, such as some bigger sq. tube, various round tube, and possibly a full length I beam for a possible future splitter project. Maybe some U channel, and...
Seriously, if you know someone that works at a steel company or someone that makes large orders at work from a steel company, inquire. The price may surprise you. They can tag your order onto theirs, and that gives you massive savings, and if you order enough, the company saves some too. I bought this stuff much cheaper than it would've been at TSC, it's 12 bucks for a 4' length of 1" sq. tube there... and 7.50 for a 4' length of 1/2" sq. I saved a #### ton of money on this little project.
