Ok, here's where I'm at now. I didn't get enough flap disks, so I'm about 20-30 worth of sanding away from being ready to start marking and cutting. Sucks, because I had the time to mess with it tonight, but didn't have the equipment. Hate when that happens!
I changed the plans a bit. I'm going to run angle for the front and rear middle legs. I have a couple questions though.
On the front, I'm going to use a piece of thin wall square tube for the top shelf support. The shelf is pretty narrow top to bottom, so this will keep it from having an annoying lip. I plan to keep my slag hammer and electrodes on that shelf and don't want to have to reach over a lip every time. Can I just cut a short piece of tube, weld it into place, and cut the next piece of tube and weld into place for the front support?
On the back, I planned to use a piece of angle for the shelf support. How do I run a angle across, a angle down, and an angle through? I am having issues picturing it.
Basically, the front left center leg has one piece of tubing running perpendicular to it. The back left middle leg has two pieces running perpendicular through it, and the back right middle leg has one piece running perpendicular through it.
Maybe a picture will help?
