In a quest for a host for the Nigel Lawson MPD18 MK2 bogey I am building, I started looking at small speeders. I found a number that appear to be an appropriate size.
Speeders like these were commonly used as railway inspection cars.
Today most are owned by individual owners who take them out on excursions.
But these speeders are too modern for my layout. I was hoping for a small speeder from the 1900 to 1920 era. Then I came across this photo.
Now we’re talking. This speeder has open sides with roll down side curtains. Because this will be a freelance speeder I won’t need to be concerned about differences in wheelbase and I can build it to fit the bogey. Given this speeder’s hand-made look that is probably what happened with the prototype.
Here’s a side by side comparison.
Wheelbase is within range. If I position the motor at the back and extend the front a bit, I can incorporate seats for the driver, especially if I bend over a portion of the tabs sticking up in the left side of the bogey photo. Here are takeoffs incorporating the bogey and my estimates from the photo. I converted takeoffs to 1:1 dimensions as some of my estimates assumed a 6′ man which I converted to 1/87 then to HO in millimeters.
I could build the speeder as shown in the photo with the canvas sides if I enclose the motor in an ‘engine cabinet’. Deck length and width are for the bogey. Cab width is the width of the cab. With a cab width of 60″ and a motor diameter of 27.4″, with the engine at the back, there is plenty of room for a bench for the driver and an assistant. If necessary, the deck base could be higher reducing the height of the engine compartment in the cab.
I started with a 3D CAD program called TinkerCAD. After taking a few lessons, I took a shot at modeling the cab in TinkerCAD. Here is the result of my efforts.
So the pressure is on to finish the Bogey kit build so I can start work on the speeder. Oh yes, a 3D printer is now on my wish list.
