3/4-inch scale B&O P7d Cincinnatian

Post by Andy R »

A little over 10 years ago I purchased a very incomplete start of a 3/4-inch scale B&O P7, (3.5-inch gauge), the famous "President Washington", from a live steam friend who decided to build much bigger locomotives. Because I have recently substantially completed my last two locomotive projects, a good friend has asked me several times "When are you going to post about your P7 project?"

In the past few months I have been able to do a lot of work on the project, so will attempt to document what has been done the past few years (my they do fly by!), bring the project up-to-date, and keep up the description until finished. So I hope that this thread will be interesting.

I figure that I am at least the fourth owner of this adventure. What I bought 10 years ago consisted of longitudinal frames, with driver axle boxes fitted, much of the brake rigging parts, the trailing truck sans springs or spring rigging, the pilot truck, the cradle, the drivers mostly machined, and a few other bits and blobs. And some drawings. The original builder fabricated much of what is currently available, instead of using castings that are now available from John Kurdzionak at Friends Models. Curiously, there are a few parts fabricated in duplicate. This photo shows two crosshead guide yokes (Part No. 1129) and two frame crossties (Part No. 1134). Only one of each is needed.

The frame crossties are machined from solid, and the two crosshead guide yokes are fabricated from steel to very closely mimic the castings. They match the drawings quite well. I have wondered why so much was fabricated. Did the original builder like to spend time fabricating instead of machining castings? Maybe he couldn't afford castings? Were castings even available when he started? And why duplicates? Perhaps two guys were working on a pair of locomotives and splitting the work between them? Like I wrote above, it's been over ten years and I don't have an answer.

For inspiration, here’s a photo of DaveD (who contributes to this forum) and his B&O Pacific.

DaveD must be a very small person.
He is dwarfed by that 3/4" scale locomotive...

That is stunning looking!
How many of the 1.6 scale P7s have been built? I feel like at least 2-3?
