Burrell Traction Engine, Horn plates (Part 1)

Burrell Traction Engine, Horn Plates (Part 1) If you have read the blog thus far then thanks for putting up with my bad English.

The castings are in the as-delivered state, and require some thought to machine ....! The bearing halves for the crank bearing, photo from Bridport foundry. It's bronze material I'm told, I guess its the better new old stock. We will see when I start to machine it. However, all in plus postage £30 for this slab.  Finally, the finished shaft tubes with the preserving Red Oxide paint finish preventing any unwanted corrosion to the fresh cast-iron surface after machining.   (Note the empty Gin bottles are not all mine I do have help). A start has been made on the larger of the 2 bearings and a Mild steel accurate gauge plug has been made. This is t
