ABS is easier to cut the spacer but you still need a way of doing it.
It could be done on a jig saw with a removable blade. You drill
a hole in the spacer material. Put the blade through it and proceed
to cut the straight lines.

Hang on to the air pump Doug. Makes a great and long lasting vacuum
pump to power your gyros. A bit heavy but well worth it.

BTW Tom this 3D shows the rectangular flanges.
Ignore the slots in the plates people as Tom idea was to go to
a thicker spacer and attach the slide throttle push pull
rod to the Teflon another way.

Yeah, I understood from your explanation.  I didn't include the holes in the middle of the inside plate for the flange attachment.  I'll add those to the program.  T.W.

On the ABS solution.  We may be able to use a router and template to cut the spacer. If the ABS is appropreate for this use.  Match drill the spacer to the front and back plates.  I can cut the 3/16" 6061 T6 plates and the flange. Maybe thats all we need to cut... T.W.

No need to do add the holes to the program. That way one program for both
plates.  The outer plates does not have the holes as tubes should
be welded on. People can match drill those side flang holes. The side
flange holes in the  back plate  also need to be countersunk from the
inside so the Teflon can slide by the flat head screws.
