Had to laugh, I did that once in a junkyard about 20 yrs ago. I was way in the back, and my bowels said "right now", I never would have made the gate. So, since I'm a mopar guy, I squatted behind a 4-dr Impala and left the yard without socks. Not my proudest moment, but sometimes one must improvise.
Just so I'm not hijacking the thread, here is my homemade cart. I totally agree building your own is best, especially with a new welder. I saw some cool ideas here that I'm going to add to mine.
When I bought my welder I asked about buying a cart. The saleman said they had carts but suggested I build my own as a good way to get acquainted with the welder. So, here's mine. It's hard to see, but I hang visegrip type clamps on two half inch steel rods welded on the back and right side of the cart frame. A few changes I would make are: Use 1" angle iron to create a lip around the top and middle shelves so the visegrips and clamps don't fall off. Use expanded metal for all the shelves to let the crap fall through. Rubber casters instead of the plastic ones I have.
