Any progress on the simple PSRU? I have a neighbor that is a retired
  millwright, and he has a 12" metal lathe in his basement. He has been
  building mini steam engines in his basement for a while- a steam powered
  mini ferris wheel, locomotive, etc.

  Last I remember you were discussing using the ceramic bearings- and were
  trying to get them from China. If I can get an idea of the internal parts
  and where to get them, I can try to make one.

  Have we made any progress lately?

  It will be awhile. We had a ceramic bearing supplier picked out but there
 was some
  evidence he was less than reliable. We are attempting to finding another
 source.

 I assume the heart is a Ford planetary, but where does the splined shaft
 come from? Do we have to machine the splines on a shaft?

 Kevin Alderman


 It must be welded up from a  manual transmission, one inch diameter,
input shaft or
 Ford auto tranny splined part. Tracy uses the auto tranny part.

 OK, I guess I need to go get a used E4OD and tear it apart and see what's
inside.
Sounds like fun!

Kevin Alderman


No need. New parts are cheap.

I have ordered from them and I think Tracy also buys from them.

Here is an outfit on the west coast.

We are in the process of ordering the bearings in china now.

The smart thing to do is let us build one and see if it works first :)

You can order thin section steel bearings from mcmaster carr
but steel thin section bearings are limited rpm wise.
we are using the 4 inch size.

This is why we are trying to buy ceramic thin section bearings.
Cost is the reason for buying them in china.
