Where are you Roland? - Galesburg, Illinois

We are also in dire need of a gear box maker. The Ford planetary
has been working great since 1973 but our most recent supplier
retired.

Would need to know some more about the gear box - Any good drawings
available
and/or a sample(s) of what used to be supplied ?

to pursue it - Recently sort-of-retired and have a pretty complete CNC
machine shop - Eventually would like to build for small homebuilt aircraft
application -
75 to 125 hp with gear or belt reduction of my own design - Background --
Precision Machinist, Tool and Die Maker and Mechanical/Aeronautical
engineer -

Suggestions, comments and other approaches to consider are welcome

Here are some suggestions for gear boxes.

The old Ross with needle bearings was ten pounds lighter than

Tracy Crook's later design. The Ross was built between 1973

and about 2000 or so. Hundreds were sold. I think Tracy sold at least

100 over the past 14 years or so. In the meantime

Ford kept beefing up the planetary trannie it was based on and the

latest versions are used in the 650 ft pound Power Stroke Diesel.

These six pinion gear sets are less than $200.

I can supply IGES on everything I have. Do you have solid works
or a MasterCAM program that converts IGES files to G code?

If not I highly recommend Rhino 3D.


I can also do a new 3D with IGES on any changes you need.
