Test pilot/cow-catcher

We made a test pilot out of wood to ensure we got all the deminsions right. Wood is a lot cheaper than brass if we made a mistake. Having the deminsions correct, we'll make the real pilot out of brass angle.

These wheels are just the hubs(rims). We are going to shrink tires on the wheels, just like the prototype.

We have one good cylinder and still waiting on a second. The original foundry poured two, but only one came out right. The second, had the porting wrong. We switched foundries and are currently waiting on the second cylinder.

You can see the difference in the two cylinders. The one on the left came from the foundry we are currently using. Although it would work, the appearance is drastically different. The foundry is pouring a replacement cylinder for us to match the existing cylinder.

The rod stubs and bearings are made up of indivdiual parts as was the protype. These are not a one part rod like most rod castings. Our rods have a total of 10 parts to make up one rod.
