Paul, I don't know if you have this covered in your drawing,
but there is an oil seal of some kind pressed into the TC PSRU
base plate. I'm shipping it out today to Jeff.

Yes the oil seal counter bore on the back side of the plate is in the
3D I sent to Jeff.

Here it is in Tracy's dwg.
Did you notice a shallow counter bore on the front side?
I am not sure he is still shipping them this way.

What is not is the mounting holes for the starter. I found an error
in Tracy's dwg so I left out the holes. It is easy to match drill
the holes once you have the 2nd gen starter.

Jeff, please take some pictures of the final product and send them to
me.

I'll put your name in address in the parts for sale section on the web site.

BTW we also need some one inch OD spacers drilled and two of them counter bored
for the hollow dowel pins. That can easily be done on a manual lathe.
Of course an NC lathe could knock out a bunch at low cost.
Craig has a set of spacer blocks from Tracy's that are rather crude
but the correct length can be determined by measuring those.

Answers. No counter bore present on this plate.
I have pictures, will send later today.
Are you talking about the blocks that support the plate from the engine?
I can photograph and or measure the hardware supplied later today after I get back home.
C. Smith

Thanks.
Yes about the blocks.
I suggest we replace these with spools made from one inch diameter aluminum
rod. Then tig weld 3/16 thick 6061 T6 plate between the spools as in
these pictures. The 3/16" plates take only the modest shear load due to
the 200 foot pound engine torque. The 700 foot pound prop torque is
taken directly by the motor mount/adapter plate combination.

Its optional. It is mostly a weight issue. The blocks
are too heavy for what they do however they do work.

Did you ship the stock Tracy plate off to Jeff yet? Are you shipping the
blocks as well?
