Do any of you know where to find an under 40$ turn table?
You could do that easily by making it yourself. The hardest part is starting it. I made one by cutting out the hole and mounting a pirce of 3/4" plywood with spacer blocks to the underside of the layout. I centered the hole in the center with the pit and then put a piece of brass tubing in the hole. I made a scree to the shape of the pit and the wall and spun the scree to make both at the same time. Worked like a charm and I think I have the only turntable in the world that can handle a Big Boy and a tank engine at the same time :-). After the plaster sets you can install the ring rail and build your bridge.
Yes i do
Look in the Walthers Catolog for the scale your modeling in.
The Atlas turntable has its flaws, including the drive system which pauses for each track and which uses a distinctive track spacing assumption, BUT thousands have been used very reliably over the years and it is frequently available at discount prices
Heljan has a turntable that is inexpensive but calls on you the modeler to do some wiring work. These are both HO by the way
