Motors from 1/4 HP to 1/2 HP are a good sizes for motorizing
kickwheels. I wouldn't want to use anything smaller than 1/4 HP.
The motor should run at about 1800 RPM. A 3600 RPM motor
will indeed run too fast.
(I learned to throw on a motorized Estrin wheel in 1972.)

I converted my 50 year old kick to a standing wheel--i.e I can throw
standing--and gave it a 1/4 hp motor I had lying around. It is the common
arrangement of a motor driving rubber wheel which drives the flywheel.
Although I tried both this and that, the motor is much to fast/strong. What
are the specs on the motor of the Estrin that has been discussed? And what
do all the experts suggest I get? (Pref something findable in junk
yards....)
Thanks

Be of good courage

Miz Lilli --
Just a thought here -- you say the motor is too fast
*and* too strong. That being the case, there may be a
solution in relocating the motor or changing the
rubber drive wheel on the shaft of the motor.
If you have the motor mounted so the rubber drive
wheel 'rubs' anywhere except the outside rim of the
kick wheel, moving it towards the outside will
correspondingly reduce the velocity transferred.
Likewise, if the rubber drive wheel isn't already
tiny, replacing it with a smaller wheel (or, if you've
got a great big solid chunk of rubber there, just
sanding it down, an easy if smelly job using the motor
to spin the wheel, etc.) will reduce the velocity.
Depending on the mounting configuration these might
not be useful approaches, but if they are they'll keep
costs down.
