This is our new zero backlash shaft brake.

 

These examples show the old shaft brake.

Standard Mounting Example using the NYRS mounting bracket with a brake. Notice that there is a bushing on the pit bottom and also in the little box hanging below. This is a very good shaft support.

CMR Turntable Mounting Examples - Here are a couple of examples of mounting a brake to a CMR turntable. You could also use our regular mounting bracket as shown in the Diamond-Scale photo.

 

I like this one because nothing can move. It could be tricky lining up however because the motor and the shaft have to be in perfect alignment. Any binding going through the brake will keep it from engaging properly.

I assume the material this is made of is acrylic which is very brittle, could break. CMR turntable.

Misc - Bowser, etc. - All the Bowser turntables I have seen are like this. No bushing. I've recently heard that they have added one. It really needs two like the Diamond-Scale.

 

Connections

We recommend having one side of your power line go to a one piece ring rail, and the other come up through the shaft. Here is how we do it.

A wiper connected to one side of the power pack, DC or DCC, it doesn't matter.

The other end of the shaft is connected from the top of the shaft to one of the bridge rails.

We especially like the block as it permits the bridge to float a little for uneven bridge rails.

The other wire is connected to the ring rail and power is delivered to the other bridge rail via wires from the bogie trucks or better yet, bogie trucks and a Tomar wiper like this. The wiper insures connections and helps when sound equipped locos are on the bridge.
