I missed the flywheel part and forgot about this Bob. Getting old :)
Yep this will work well and if you want to build it and sell
it be my guest. Easy to install and maintain.
It  has also been on the ACRE NL web site for at least five years.

Low cost eccentric shaft position sensor that works on any rotary.


The drawing is for a Ross clutch disk so it needs to be redrawn for
Tracy's dampner plate. Tom Webber can cut these disc out of metal
no problem. It may need more holes to match the number of pulses
per rev that Tracy needs for his computer.
Tom will be back from vacation Sept 6th.

Here is another little trick that we used
on Perry Mick's engine. It is hard to get to the front timing
marks on most aircraft installations while the flexplate is right
out there in the open.

Hi Paul,

The idea I've had kind of floating around in my head is use the RX-8
pickup, but make a steel plate, to be installed on the flywheel, with
notches that would generate the same pulse pattern as the CAS.  I
haven't done any checking on the feasibility.  If it can be done, the
pattern could be used on the front pulley location also.  By using the
same pulse pattern as the CAS, Tracy's computer wouldn't have to be
modified.  He has different software for the RX-8 and CAS signals.

I hasten to add that I'm not doing anything about this until the engine
is running and the plane is flying.  All I've got left is to make up a
couple of fuel line hoses, the oil hoses, and do the electrical.
Shouldn't be more than another year.  (I'm tired of making predictions
on completion and being way long.  I plan on beating this one.) :-)

I like Perry's timing indicator.  I'm planning on making timing marks on
the flexplate also.
