Running Boards & Frame Ext - June/July 2021


After the last update on the cab, I had the boys start fabricating the running boards. I think there are about a million holes in those boards! To try to keep things lined up and looking good, I made a drill timplet out of brass and then bolted and clamped it to the board, so that all of the holes could be drilled. After many hours of drilling, they about wore out the drill motor!

   Once the running boards were finished, I directed the boys to work under the cab to get the rear frame extension built. I still have not designed the draw bar to the tender yet, but it will need to be done before testing the engine on the railroad. With the rear frame in place, it was time to move on to the firebox.

   Intinse is the word of the day here! I have never seen so many stay bolts and rivets on one forebox! With all those in place, I directed the boys to build the ash pans and details on them. After all that "fun", I decided to give the boys in the shop a break for at least five minutes, before we move to the front of the boiler."  -  Barry
