Design to make castings for Soule Speedy Twin Steam Engine

(1/5) > >>

CI:
I thought I had posted about my efforts to make 3D models, and then 3D printed patterns and castings for the Soule Speedy Twin engine on this forum, but I don't see it anywhere.

The story is that someone on a casting forum mentioned that the factory that manufactured Speedy Twin steam engines (the Soule Foundry in Meridian MS) had been converted into a museum, and had a yearly show, where they ran all sorts of steam engines from a large package boiler.
The original foundry and cupola are still at the Museum, as well as the fully functional original line-shaft-driven machine shop, the pattern shop, and the Speedy Twin assembly area.
I attended the show a few years ago, and was blown away by how much original equipment was left intact.
There are tables and shelves that contain stacks of Speedy Twin parts, ready to be assembled into running engines.
The pattern shop contains most of the patterns and coreboxes used to make the Speedy Twin molds.

And a few of the original Speedy Twin drawings still exist.

After seeing a Speedy Twin operating at the show, I decided to try and cast a scaled model of the engine.
Photos attached are one of the Speedy Twins at the Soule show.

Here are a few videos of a Speedy Twin in operation.

Here is the ebay advertisement I saw.
I don't think anyone realized exactly what this engine was, but since I had seen one at the museum, I knew it was a Speedy Twin.

I had to drive to Chicago to pick it up, but the price was right.
The engine is disassembled, which is what I want, since I am restoring it piece by piece, and measuring it as I go, to create 3D models for each part.

I have been sandblasting some of the parts, which has revealed a few repairs.

CI:
More cleaned parts.
