Paul,  what do  you think of using 3/4 o.d. x .438  i.d. seamless steel
tubing for the spacers?   Wall thickness is .156 inch.   Local outlet
has about 8 feet on hand.  Jerry

I was going to ship you some with the beams. I picked up two 3 foot lengths
when I bought the extrusion. Industrial Metals Supply in Burbank has 
several hundred feet in stock.


Go ahead it will save me some of the cost of shipping:)
