Folks please don't send dwg files. Learn how to plot them as gif out
of ACAD. I had to first load this into Rhino, export it as a ACAD V12
dwg file on to floppy disk. Load that into ACAD V12 on the DOS computer.
Plot it as a gif. Save the gif on floppy and then load that into
the Linux computer. Stupid ACAD cannot convert its own files to earlier
versions of ACAD.


BTW reading the Skyranch Ranch Engineering manual about all the bad things
that can happen to an aircraft engine makes me damn thankful for the
Mazda rotary. At least all that happens with a 2 mm apex seal version
of the rotary is a fractured seal. You should read what happens
to an aircraft piston engine when pre ignition or detonation occurs.
Everything from burned holes in pistons to stretched exhaust valve stems.
You can't burn a hole in the cast iron rotor and there are no exhaust
valves to stretch.
