[TheForge] Steel frame capacity...

Mon Jan 20 11:03:01 2003

Jeremy:

Depending on your welding skills, 3/4" sq. tubing would more than carry 300+
lbs. Modify your design with angle stiffeners on the legs and you'll have
all the carrying capacity you'll need.

Still, I'd use 1" sq. tubing for the legs and angle stiffeners and 1" x 1"
angle for the frame. Run the angle stiffeners about half way down the legs
and it'll be fine.You could also build it entirely from angle iron and save
a couple $ unless you have a selection laying around.

Larger steel won't hurt, especially if you're welding skills need work.
Around 1 1/2" + sq. tubing and it'll be rigid enough without stiffeners but
it'd be overkill, especially if you have to buy a stick.

If it ain't forged
it ain't real.
Wrought iron is.
