No, the originals were multi spoked like the wheels on the Stephenson's Rocket. I decided to make them three "spoked" because I haven't done very much of this "window cutting"  and I needed the experience. The multi spoked wheels on the Rocket were made of steel so I could weld all of the spokes. These wheels are made from aluminum, and I don't have any experience welding aluminum.

And we spent a goodly portion of the day on my lathe, making shiny wheels. The two wheels on the right which have raised bosses on the face are the ones which the gears attach to. The wheels are finished now except for cutting the windows in tomorrow on my mill and rotary table.

That went well!!!  I still need to do a bit of hand filing, but very little. These four wheels are straight off the rotary table with no other work done on them. Putting in the windows was not difficult, but was time consuming.

I have reached the end. The engine runs very well, and is completely finished mechanically. I started this "design and build" on the last week of August, so it has been about a ten week job. My next step will be to paint the engine and then it goes up on the shelf with all of my other engines. Thank you very much to all of the people that had a look, and thank you for the comments that were made as I progressed with the build. I hope you enjoyed it.---Brian

A stinky business!!!--Wish I could have done this painting a month ago when it was warmer outside. As things set, I open my big garage door, set out all the stuff to be spray painted, paint it, then move everything into my machine shop so it will dry enough for a second coat. This comes out to four trips into and out of the garage (2 coats on each side). My house smells like a body and paint shop. I am fortunate to have a very understanding wife!!!

So, the Trevithick is completely finished. The painting was finished 3 days ago, and it was all reassembled this morning and posed for some "beauty shots". I had a few issues with this build which involved the cylinder and the 4 way valve, but in the end I used a more conventional slide valve and finished with a well running engine. Thanks for riding along with me, and saying 'Hi" once in a while. It is a very pretty engine, and now it will go up on my shelf to the place of honour along-side the Stephenson's Rocket.---Brian
