A pair of good plates. Pretty close to the original. |
 |
Next to be made is the piece with the slot in it. I used a piece of brass .125". It just happened to be close for what I needed. |
 |
The piece is solder to a sacrificial table. This works better than trying to hold it in the vise. |
 |
The table is bolted on a piece that is held in the vise. It is now ready to be whittled down. |
 |
The finished part after much whittling. A slot down the center and a hole in the end for a pin to hold the cover plate. |
 |
A bit of test fitting. |
 |
Next I made an assembly jig using one of the plates. It's ACC'ed to the aluminum to hold it while drilling the holes. |
 |
Drilling out the holes. I'm using a piece of MDF so I won't hit the hardened vise and ruin the drill. |
 |
Small brass tubing is used as axles for the pulleys and the to center the two plates. They are cut long and will be filed flush when everything is soldered together. |
 |
When I milled the long part to size I took a bit to much off and had to shim the plate up about .016". So I made a small shim. It fits around the center post. |
 |
And here it is all finished. The only thing left is a hole in the end and bit of filing to make the left hand end round like the original. |

The New York, Vermont & Northern Railway electrical engineers had a very heated debate as to whether to go with DCC or R/C. The decision was made to go with R/C because it will not be used on a daily bases as an locomotive would. The engineers found a company that had a new product, the receiver, for use in the model railroad hobby. So here are three pictures of what will be put together to make it function. Notice how big the Receiver is? |
