airbus: I used 2-1/4" metal rods purchased at Lowes. I just made a platform from a 1X4 base, X 36", attached 1X4X6 accross the top. Drilled through with 1/4" bit using a 6" stove bolt with wing nut and a 1/2"X1/2"X6" top cross piece to hold the rods in place. It is real simple, but works. The difference in mine and Greeat Planes, who I don't think carry them anymore, is they use metal for holding the 1/4" rods and I use wood. Wish I could furnish pictures but my computer skills will not permit me to be that advanced so I don't have a computer camera. I'm still using the old outdated 35mm Nikon.
