Guys...,


We can hook you up with either a 1.5'' Sunbeam or 2.5'' Pyle K-240. We're acting as an agent for MidWest Models, simply forwarding sales. They're doing a Batch of the K-240 turbos for May of 2012. I know 5 are sold through me, and two of the Sunbeams as well. You can contact NGT Models to order.

We don't make any money off these sales..., so this isn't me pitching anything.

Yes, exactly what we're looking for.

I've got hundreds more hours on mine than any one could count no failures in 20 years. You're on the wrong track with the recorder motor. Unless you are building 4" scale and the bearings are too light. A standard slot car motor with sleeve bronze bearings and a single 60 bucket turbine is in mine. Good luck with yours.

It was only an inquiry, Andy, not a challenge! Best of luck with your product, and continued success!

This subject holds an interest for me. Out of curiosity, has anyone built their own generator/alternator for these miniatures? If so, has silver been considered for wire instead of copper? It is a better conductor, but only marginally. Would there be any benefits?

Didn't LS Supply use and off-the-shelf motor in theirs?

I believe they did. At the rotational speed that the turbine revolves brushes and bearings will lead a short and miserable life if the armature windings do not bird cage first. I also believe they took molds from the Mosely turbogenerator.
If not they copied the errors in the Mosely castings exactly.

Howard
I sent you a PM about the castings for the generators. I am interested in a set of castings for one. I can machine them.
Please let me know the cost.

Thanks Tim
