Shortly after discovering Big Ben's Bricks, I found myself dissatisfied with any of the alternatives for driver rods (connecting and side rods) on brick built steam engines. Out of determination, I have produced driver rods that are compatible with BBB and Lego's steam engine wheels for my own use.
After some tinkering, I'm now offering these rods for sale to the AFOL community as well. These parts are designed to be driver rods, they are a little thicker than a plate and a little thinner than a 1/2 Technic beam. This odd thickness is deliberate, the rods are designed so that they should not rub against the rim of the wheels. The rods float on the pin cuff- compatible with 3/4 pins or full Technic pins. So now you can paint the rims of your driver wheels if you are so inclined.
Given the wide array of possible configurations and the limits of my pocketbook, I have opted to fabricate these custom driver rods using rapid prototyping technology. As a result, the possibilities are literally endless, e.g., half stud offsets for BBB small drivers should be feasible.
My store only contains those driver rods for which I have completed designs and fabricated at least one copy. Other configurations are feasible, contact me via Bricklink messages and we can discuss (I can't guarantee that I can make everything, and in any event, expect a longer lead time on new parts since I will have to design it).
The surface of the driver rods is a little rough because the fabrication technique, but it is hardly noticeable except when you are extremely close up. There are only a few fabrication colors to choose from- gray, black and red and I cannot adjust the colors. Fortunately, the gray is pretty close to light-blay. I have not yet tried the other colors for a match to lego colors. As such, black and red are only available upon request (again, contact me via Bricklink messages).
Visit my Bricklink store to order the rods or find more information about production. These are a labor of love.
