Picked up the parts on Friday Jerry.
Will ship six on Tuesday as monday is a holiday.

Here is a pic. Slightly less than 3 pounds.
Could take another pound out by punching a bunch of 1-1/2 inch holes
in the sides at greater expense. Each hole would save .025 pounds.
30 holes would take out 3/4 of a pound. It would look cool :)

If you must beef it up skip weld a 1/4 inch wide strip along the top
flange. This will prevent flange buckling but I don't think it is
necessary. Calculated stress is less than 40,000 psi with 300 pound
engine and 6 G's.

It would be nice if you supported both ends on 2 by 4's and
lowered the truck on the middle. Use a 12 inch square 3/4 plywood to
support the tire.

It is beautiful.  I see no reason to lower the truck on this beam,
It's structure (2 inch sides)  is stronger than the one I already
tested and proved adequate.   I don't have a way to punch the
lightening holes but I could drill them if somebody wants them badly
enough.  I'm having trouble visualizing the 1/4 inch wide strip welded
along the top flange.  Can  you send me a drawing?     This is a very
nice looking piece.   Thanks,  Jerry


I was thinking of punching the holes in the next batch. I could get
a quote from George but I don't think it would be cheap :)

I'll make a sketch. Here it is.
