Paul,
Do you or anyone know the weight of the automatic flexplate with the
starter ring attached?
Thanks
Doug - shaking in Japan.
I have one up at the hangar but not planning on going there
in the next couple of days. Figure the volume of a 12 inch disk of
3/16 thick
steel at a density of .3 pounds per cubic inch. Then take half of
that for the large holes and you will have a good guess.

On my old spring style postal scale my AT flex plate weighs 1.83 kg
[4 #].
Interestingly the balance that it bolts to is also 1.83 kg. The bolt
ring weighs .12 kg [.264 #]. and the six bolts that hold these three
pieces
together are .12 kg too.

6 x 6 x 3.1416 x .187 = 21 cubic inches at .3 pound per cubic inch is
6.34 pounds
half of that is 3.17 pounds not that far off :)

The flexplate weights vary by generation (and year?). Here are a few I
have measured:
S4 - 1913g + 120g plate + 122g for 6 bolts
S5 - 1891g + 242g plate and 6 bolts
S5 - 1840g + 256g plate and 6 bolts
S6 - 2251g + (bolts included?)
Here are the numbers for an 87NA automatic rotating assembly:
Front CW + washer - 1274g
Front Rotor "D" - 4609g
Rear Rotor "C" - 4633g
Rear CW - 1861g
flexplate - 1913g + 120g plate + 122g for 6 bolts
eshaft - 6788g

Paul and guys,
Thanks for the quick response. This info has saved me an afternoon of
work. Some good news. I am now back in the saddle with free access to
a complete machine shop again. Michiwa is now teaching at an industrial
art technical high school and their shop is well equipped but not used
between 15:00 to 19:00. Monday through Friday. I`ve ordered Aluminum
pipe and Teflon sheet, and Aluminum flat bar from Metals Online so I can
make up the P port housings and slide throttles. I hope to make and
accurate step on the inner housing wall but the shop doesn`t have a
fly-cutter. Guess I`ll have to make one or borrow one.
Doug.

Hi Doug;
Much easier and more accurate with a boring head arbour (queen's
english). I think I paid $40-50 years ago.
