Restoration of AT&SF #3780
- Thread starter Ray Marinaccio
- Start date
Due to the lack of available replacement parts, most of the drive required fabrication.
After a few days of hair pulling, measuring and calculations I worked out a set of gears that would produce a 55.9/1 final gear ratio.
This photo shows the rebushed idler gears, the larger motor and what will become the primary gearbox.

The test run went well, all things concidered. I may need to adjust the wormgear clearence to quiet some gear noise in the forward direction. running in reverse it is quiet as a mouse.
Updates will be posted as the restoration progresses.

Great work. What a truly fascinating project.

Geeze Ray, outstanding project, brilliant work. When you get the time, you know I have a couple of engines that need extensive work, especially that switcher I paid $3 for up in Prescott...
Folks, I gotta tell you a funny story. We were up in the Prescott train swap meet a few weeks ago and were getting ready to leave. I looked around to say goodby to Ray and didn't see him. We couldn't believe he left already, when I caught a glimps of his wife. We we headed in her direction we finally spotted Ray and his son on their hands and knees, digging through boxes of parts under some guy's table finding one treasure after another. Ray's son was proudly holding up an engine shell, "man, look what I found." I have a good idea Ray is passing his talants on to the next generation. I have no doubts that between them they could strip a prototype engine apart and rebuild it if they wanted to......

Funny you should ask that Lighthorseman, I got that nickname at the trucking company I used to work for when I modified a trailer to carry 200' crane beams to steer it around corners. Or was it the modified trailers that cheated the drive-over scales by rapidly changing the air preasure in the air-springs as they drove over the scale.
Thanks for sharing that story Don. That's probably where half my collection came from is from those under the table deals. The search is as thrilling as the find.
And yes, I have infected my son with the hobby. (My wife too.)
As for rebuilding a real locomotive, thats one of those dreams I have. I've got a start on that dream, an old locomotive bell. Not much to go on but it's only a dream.
Thanks for the support.
