In the late 90s I machined almost all of a 13b gearbox from a set of
 plans I bought from a fellow that used the design on a Subaru (going
 from memory here).Based on C6 planetary set.Not the same as Tracy's BTW.Weight would have been between 30-35 lb. Sold the gearbox parts to a fellow from Florida I believe.

But find those plans and you'll have your 35lb gearbox.

That's funny. Maybe Tracy wound up with the parts:-) Got any drawings or IGES or pictures you can share?

What would you charge to make a one rotor shaft out of a two rotor shaft.

Paul Lamar


Paul, What does it take to make a one rotor shaft out of a two rotor shaft? I have access to machine shop equipment, and would like to try, and do the machining. Also, do you have the end drawings for CCNing in aluminum?

Well it means cutting one of those eccentric lobes off.
It is kind of hard on a lathe unless it is huge. That is because it is a non continuous cut. A tool post grinder might work better.

I don't have the end housings designdone but will work on them if you can cut some.

Where are you Norm?

Paul Lamar

I have a 14" lathe and have managed to shave off a lobe without difficulty.

There you go. Send your e-shaftsto Milo Burrows.
How much Milo?

Paul Lamar


The one rotor Eshaft shown has been shortened in addition to removing the lob.
I am not at all sure I could cut the remainder smooth enough to work for you.
If you want to bring your shaft here you can use my lathe to cut the lobe off for sure.

Thanks for the offer Milo. Milo is in the Seattle area.

The way to do it is leave it several thousandths over size and have it
ground to final dimensions. The same diameter as the rear bearing surface.
Any crank shaft grinder I think would work in that case.
