don't buy your steel at a welding shop. you will be paying extra middlemen. i will have to say that I purchased my steel before the big price increase, but it shouldn't be that much more.

i bought two sticks of 2x4 and two 1x2.

i got a dimensioned drawing of the frame, and made a drawing on autocad. i'm not exactly familiar with a 27 frame, but i'm sure it's a simpler design.

all you need is a good welder, a metal chop saw, measuring tape, level, and a little arrogance.
