Good morning Georges Finally I did,t go to Sun&Fun it's my birthday
today and my wife did organized a party surprise brunch yesterday
and I was ready to go Saturday and comeback Sunday, anyway it will be
for next year .


I am sending you more photos of my gearbox attachment.


JEAN PRUDHOMME INSP,



Jean, NOW THAT’S IMPRESSIVE. I need to catch up on Paul's site to see
if there are additional details. Did you have any problem with the
bolt up to the back of the Mazda engine. If you are not using a
drawing I sent you could I have one of the interface you came up with
If you are using "standoffs" between the block and gearbox you might
save time getting them from the Cozy Girls who do CNC milled versions
that really look impressive. George Grimes




Paul and Georges

Almost done before assembly. I do have the end shaft to be treated
22mmX 1.5 for the safety nut and groove one one side to lock it .
Then treated and annealed both shaft at Rockwell 60. I will try to
go at Sun&Fun this Saturday and comeback Sunday. Few photos for your
interest.

Clever use of a sprint car quick change bell.

Those big ball bearings are way over kill and very heavy Jean.

A planetary puts no load on the bearings except in a spin or stall
and then it is not much.

Much lighter to use needle bearings like the Ross. Old Lew Ross was a
good engineer and he got it right back in 1973. RIP.

Jean's box will work of course. Just heavier than it needs to be.

That is a great idea. I like it. That will save weight and simplify.

Pretty expensive :)
