Paul and all,

There are companies out there that use lasers and robotics/cnc
positioners to cut tubing. I believe Legend Cub uses one of these
companies to cut the fuselage tubing.  I still am having a hard time
with the quantity of parts needed. It's no wonder the price is nearing
$100,000!!

The company that I am famaliar with near Oshkosh has repetative cuts  for
the airframe parts they make for several kit manufacturers. Usual
quantities of 5 to 20 assemblies at a time. They make the first unit
(tacked) then disassemble and make marking jigs from a closely fitting
larger tube.  Silver pencil lines are then used to cut/grind by hand  for
production parts.  The welders then final fit parts in the welding
fixture.   My second set of parts for a new airframe took about 10% of
the time vs cut/grind and repeat, repeat,repeat for the first set of
parts. :-)

If you can make templates via computer and printer the work goes  very fast.

What is it you are building Dan? I can give you patterns for the end  of the tubes.

Dan,  a question I have wondered about for some time regarding making
slip jigs.  Assuming you have hand made a perfect fit in the right
size tubing how do you transfer it to a larger tube which when you
slide it over the original tube blocks the viewing of it?     Jerry
