Paul,
This is the pattern (in development stage) of the bellhousing - the

piece

that has depth (front piece) is the part which houses the

damper/flywheel

and the faceplate which the PSRU bolts on to, the square sides and

bottom

are to accommodate a starter motor at different positions.  The

backplate is

the piece that bolts to the motor and has an integral strengthening

beam at

the bottom. The sides of the backplate are shaped similar to the flat
mounting plate now available.
The rear fibreglass piece in the background (top of one photo) is my

mould

for the damper/flywheel section

The two pieces are now one piece (glued together) and are in the stage

of

filling and fairing joins.
The next stage is to put on some stiffeners - paint it and then it

goes to

the foundry.

George make sure it is 3.58  inches (90.9 MM) from the 13B end housing

mounting surface

to the PSRU 13 MM thick mounting surface so Tracy's input shaft will work.

Paul,
That's not a problem - it is 13mm thick ( more by chance than anything
else). I also made the backing plate a little extra thick for any possible
adjustment in depth. It's always easier to take it off than put it on.

All up it's 92mm allow a little shrinkage and a little dressing-off front
and back and it's done.
I did notice that some bellhousings differed from 90mm to 92mm - probably
different starter motors.

So what do you think Paul - will it fit the bill.
I didn't make it to go into business, more for my own needs and some local
builder needs. But if it helps anyone
over there - all well and good, the exchange rate is very good for you chaps
in the US. I'm a bit like Bluent in that regard.

I think there will be a big market here in the states as Tracy has
sold a lot of redrives. Your cost down under for short runs is probably less than our
cost up here. It will make our installations look a lot more professional
which will sell a lot more redrives.  More rotary engines will be installed
in experimental airplanes which will sell a lot more bell housings. In other 
words the snowball will pick up speed rolling down the hill :) 

Thanks for doing this George. Please take some more pattern pictures from the side and
3/4 views so we can see more what you are doing. Just attach them to your
messages.
