I made this steel rack last weekend after seeing one similar 
at a place that sells misc. steel in lengths.

The rack is 24 deep by 48 long by 48 high on the back row and 
24" on the front row.

 I used bed frames for the framing along with 1/2 and 3/4 sq 
tubing for the deviders and for two handles to pull and push 
around. 

I also put casters under it to roll it were I wanted it and 
used expanded metal for the base so rain will drain. 

This has to sit out side do to the lack of room in the garage.

I also had to lay an area of 8' X 10' with patio block to roll 
it around on.

 Now I have a work area of 8' X 30' long out the side door to 
weld at. Better that nothing.
