The Mott Twin Pusher
This will fit on a standard sized sheet of paper. If you have Netscape do a right click on the plan, click [View Image] and then , with the printer set with no margins, then click [Print]. Something similar should work for you folks in thralldom to Bill Gates-

On the original the ribs were made of bamboo. I use molded wood ones.1/16 X 3/32. I support the stressed ones with a straight stick of 1/16 square running under the curved rib from the leading to the
trailing edge. I'm sure ordinary sheet ribs would work.
