Hello Pork Pie, You've stirred things up nicely lately, keep up the good
work.
When you refer to the Cremona plan, would that be a Maxwell Diagram?
(A graphical method of determining stresses in a truss by combining force
polygons of all the joints into one stress diagram)
Thanks,
Dale Krumheuer
"When you design the frame, check them to the Cremona Plan. This is a
mathematik
rule system for frame work. By the way, this frame work which is shown in
the
rule book from the BNI/SCTA - for the cockpit frame - it's wrong, because
it's
not build to the Cremona.
Also you have to know, if you like to build a soft or a hard frame.
Soft and hard depends to the cross member and the way you weld them in, also
what connection/corner reinforments you use. A open knot (soft) or a close
(hard) one.
If you need a information about Cremona, let me know"
