Switching Layout - 2nd Try

Dwyane,

Next up is making the servo control circuit.


What are you using for the circuit? Reason I ask is that there is a thread going on MRH about servo control. The modeler uses a very simple circuit using a 556 timer circuit.

Have a look. http://model-railroad-hobbyist.com/node/26088

Might be helpful to others who may need a simple servo controller.

Thanks for that link will review it too. Going with 555 or 556, there are a few article on using these timers for servos

I was looking at Robert Paisley circuit 3 Position Servo Driver Circuit http://home.cogeco.ca/~rpaisley4/xServoTest555.html and modified it for two positions

also info here too

I see you have that area pretty well covered. I see I even commented on that last MRH link you referenced to.

I have given up on using servos for turnout control after four fail attempts at building the electronics. I have gone back to a tried and true solution for me. DPDT Slide switches, I have used these before with good success.

First I cut some re-enforcement pads for the slide switches and started creating pockets for pads and clearance holes for wires.

I use a 0.025" music wire and 0.0325" brass tubing for linkage to turnouts. I just make a small channel for the tubing to fit in.

I am also gluing down track and turnouts, adding frog power wire as I go too.

"Slide switches"

Slide switches or toggle switches can also be installed on the head block ties at the turnout and used as a switch stand. A target can be added on top to make them look more like switch stands......DaveB

To bad the electronics didn't work out for you Dwayne.

Nice layout of track and turnout control. Hope that works out better for you. Looking good.

I used a similar type of turnout control on my old layout. It woks very well from my experience.

I did something similar to what you have in your pictures for an N scale yard. It works well and is reliable.

I am also sorry to hear your having trouble with the servo's. Have you looked at Berret Hill's system?

Yesterday and Today, I finished up installing the slide switches for turnout control. All track shown below is glue in place too. Just need track feeder install.
