Paul,  Hopefully this will come through.  I need this in a form that a cnc will read.  It is an alloy spacer to hold my flex drive up from the face of the flexplate by 20mm.  If I have stuffed it up I can try again.  Finally starting to make progress with new engine and than test the reduction drive.  What price are the gear sets over there at the moment?

 Neil.

First we have to translate the nomenclature  from Oz to US :-)

I am not sure what you are trying to do.

Take a look at these pictures and rewrite your request.

I will send it as a zipped  IGES file and your NC shop probably has the  Solid Works
program that will load this and will generate the NC mill program.

The flex plate has a pilot on the counter weight so the bolt holes
have some lee way in diameter and bolt circle position. One never
pilots on the bolts themselves.

The pilot diameter is 77.74 mm which is about 3.000 inches.
I think the rotary was designed in inches back in 1969.
