I am going to be fabricating this lift table.

http://www.afabonline.com/table_lift_plans.htm

I have a questions about the strength of the metal called for in the plans. Meaning with my limited experience I have to say the metal is overkill. I'm not lifting full dressed Road Kings. I am lifting 4-500 lb Sportbikes. The table top is 30" x 96" I will be dropping it down to 24" x 84"

Metal Spec'ed in the plans. For Example:

The base is composed 4 sticks of 2" x 2" x 1/4" x 92" Angle

The Table frame is 4 sticks of 2" x 2" x 3/16" x 92" Angle

Most of the box tubing is 2 x 2 x 1/4" wall

The safety stop braces are 1 1/4 x 1 1/4 x x1/8" wall

I am looking to put it on a diet. Two reasons, weight savings and cost savings. I want to be able to move the lift around my garage and lean it against the wall when not in use.

Would replacing all the 2x2 angle with 1x2 14q (or even 16g) box still have enough strength?

Would replacing the all the box tubing to 1 1/4" x 1/8" wall be sufficient?

Thanks

And yes it will be welded with a Miller 135. I would have a bigger welder, but I dont have 230. So I am happy with this for now. It has welded quite a lot and for its size and price. It cant be beat.
