Thanks and, no, I don't build these for a living. I have always wanted to build working model engines, but I never had the time, or the tools to do it until retirement.

Okay,  why not?  build them for a living?   How many hours do you have in it?   any pics of the building process?

gotta ask, whats your next project?

Why not? I guess because it is a hobby, and I want it to stay that way. And, since I am not an experienced machinist I have to take my time. This model took 18 months of part time work to build and another 6 months of tinkering to get it running like the real ones. Building a scale model invariably creates additional problems that take time to sort out. Just figure the volume of a hypothetical cylinder and then scale it to 25%, and see how well the volume scales. Similar issues with flywheel inertia, fuel vaporization, ignition shorts when 18,000 volts gets too close to scale components, etc. Getting a model running well can sometimes takes a long time. These challenges can be fun, but can also be exasperating at times. That's where forums like Fieldlines.com can be so helpful.

Looks GREAT Jeff!

As long as it is a hobby, it stays fun.
Fun is good.

Hi Again,
A year and a half ago I learned a lot on this forum about building a PM alternator from a ceiling fan motor. My thanks again to all who contributed to my success with this little project. A more recent video of this model engine project is show here:

I have another new and similar project and again need a little advice. I want to build a smaller PM alternator using a 3.3" dia standard D624 fan motor stator. The motor I am looking at is 230v, 0,4A, 1550 RPM. I am looking for a 15-25 watt 12vdc regulated output at about 375 RPM. One motor manufacturer advertises the D624 frame as a shaded pole design motor. Not sure about other manufacturers designs. My question is, will the shaded pole design hinder using this stator as a PM alternator? Thanks for any insight.

I'd use Lexan window! it is amazing to see the internals running!
