If you make it out of 4 pieces 18 inches long you can taper the pieces
which will reduce the weight and the force required to bend. Tall in
the
middle taper towards the ends. Weld joint in the center. Give me a few
hours and I will do a drawing. There is an article in this months
Sport Aviation on how a guy used his bi fold hangar door as a press
break.

OK Jerry. Make it 2.75 high in the center and one inch high at the
ends.
Each half 18 inches long. Cut to required length. Or make custom
pieces for what ever length to save expensive  4130 material.

Since these are symmetrical and much easier to bend George or any
other sheet metal
shop could make 14 of each (front and back), enough for 7 beams at
lower cost.

At the expense of more welding of course. On the plus side these are
more
professional looking.

That is pretty but a bitch to clamp in the mill for drilling the
bushing holes.  Also takes me out of the shop looking for someone to
shear the tapers.   I could make a template and plasma cut them but the
finished edge would not equal a sheared edge.   I like it  and I will
try to figure a way to do it with the equipment I have..  Jerry

Its a lot of extra work but you could grind down the edges on a disk sander.
