... --- N Scale Roundhouse Turntable Supports ---

On this page we place 3 uprights and a base for the stepper motor under the turntable pit bottom.

.

The length of the uprights is going to depend on how long a shaft you use between the stepper motor and the bridge and how far the shaft is into the bridge and into the stepper motor coupling. The measurements above are what worked for me you are going to need to calculate what you need. See the preceding build page for info on how to do that.

I didn't round the bottom off until later in the build but it would be a good idea to do that now before you go any further. The purpose of this is to make it easier to mount the whole turntable assembly to the layout later. Then you will just need to cut a round hole in the layout a little larger in diameter than the print and lower the whole assembly down through the hole. If the base isn't rounded it probably wouldn't fit through the round hole in the layout.

You do need to secure the ledge that has the bridge track on now before adding the pit walls. We will deal with the bridge track in the next step and then move on to the pit walls.

I'd also put the plywood pieces that hold the stepper motor in place now. With the stepper motor in place you can install or remove the bridge and its connecting rod at any time. This will come in hand while installing the bridge track and pit walls.

You can find all the turntable files on my thingiverse.com account ( HERE ).
