How could I forget the duct tape? It's just one of those things that I take for granted and assume everyone has rolls of the stuff laying about in every room.

I saw those plans for that service cart, it did look interesting. Right now, I'm using these wheeled trays that I got for free. I think they were from a hair salon to hold the stylists clippers and stuff? I dunno, but someone was getting rid of it, I can't turn down free stuff. I picked them up not knowing what I would need them for, it turns out they're the perfect height to hold tools when working on cars.
