Industrial Metals in Burbank CA will cut and ship 1/2 plate.
Send it to me and I will use Tracy's redrive plate to mark the

position

of all the little holes and bore the place where the oil seal goes.
and the final bore on the large pilot hole for the starter.
I will then send it back to you for final drilling of all the little
holes and you can match drill the starter mounting holes.

I too am interested in this plate. Want to do another?
Marc

Sure I will do one or two but if it starts to eat into my
time we need to find somebody to make these.
I don't suppose yours will have these pie shaped cutouts will it?

Paul,
All I would need is tracy's redrive holes in the plate. I will put in the
engine holes, starter etc. in, and I may change the outer config. Will you
install mm brackets on plate?
Marc

Those are easy to do Marc. Cut them on a band saw and use a hole saw
where the rubber bushings go. Then polish the holes a bit to make the
rubber busing's life easier. I speicified 2 inches wide on that drawing
which is a bit on the narrow side so make them 2.25 inches wide.

Ok, Lets do it.
Have you tried welding on the brackets?

Could be done but that tab A in slot B interlocking slot idea is 
working real good. Very easy to make on a band saw. The quarter 
inch bolts take no real load. They just lock them in the slots. 
Also the welding might change the heat treat in the T6 material. 

The advantage is you can take them out and adjust the thrust line if
necessary. Also if they crack they can be beefed up and replaced.
Here is an earlier sketch of the idea. Drill a half inch hole in 
both the plate and the bracket at the ends of the slots before you
drill them. That will smooth the stress in that area and make it 
easier to cut the slots. Don't forget to make them 2.25 inches
wide instead of 2 inches wide. File and polish out any scratches or cut
marks.
