Got the gears for my new gear box.
This is the back Ford  planet set with steel planet
carrier. Only about 7.5 pounds.

This will allow the p-port engine to rev to about 9,000
for take of making close to 300 HP.

It will be a while before I need it so I'll slowly gather
all the other needed parts together.

It will need a custom input shaft due to the large internal diameter
of the sun gear. I am not comfortable with a sleeve.

There are a couple of ways to get the torque out of
the rotating planet carrier.

1. EDM the roll pins holding the planet shafts in and replace
them with 1/2 inch shoulder bolts. The S-bolt hardness is only C32.

2. EDM a 7/16th hole in each shaft and use a regular 7/16th bolt.

Both methods have their good and bad points.

I'll probably try the first method  first.

What do you think Larry?
