Hello David      I`m building a 750,   I used two 12 foot 2/2 steel tubes set on saw horses with 42 inch long 2//2s to go across to do the fuselage and wings, this worked well for me.    Lee

I have 6 2x2 steel tubes that are about 60 inches long.  Be sure to put duct tape on the side your parts will touch, helps keep the scratches down.

I used steel 2x2 12 ft.  long too. Zenith recommends a 12 ft. table, so I would use 12 ft. lengths.  At least you won't have to pay a cutting charge ;)  Also, I would stick with steel vs. aluminum. More durable, less sag, probably cheaper,  and impossible to bend.

Well, I went to the steel store 60 miles away in southwest texas and they had 6 already cut but order cancelled 2 1/4" 5foot long pieces for 30 bucks.  Had to get the oil off and prime them.  But the important point is I used them not to get the part fabricated off the table but as straight edeges and weights.  Some of the toughest part of the build is to offset the predrilled holes and keep the part straight.  The weight of the steel square tubing helped with that.  Used them t level the bed, and on top to weight down the parts while drilling. 

I will say I did not have the same problems on the previous build of a sonex.  But a lot of stuff was not ready to cleco together.  So the twist issue was not a problem.
