Super detailed Williams cab forward Run by with cherry switch sound triggers.

I love it!  You work quickly!

 

What'd you use for the microswitch?

It's a Gilmore micro switch.

I'm going to grab a few of these on the way home. Never liked the idea of messing with the reed switch either.

I can shape a piece of brass to work as the cam. Your method is a great idea. Plus, for an articulated I like the way it goes in and out of sync.

And this is with the GS4 sound set, and you used the extra cams to get the chuff count right?  This is making me really want to do some work on my Rail King Cab Forward.

The exhaust chuff rate doesn't sound right to me, nor does the whistle sound. The exhaust doesn't seem to be 4-chuffs per revolution on either engine, hard to figure out.

Your right HW. It comes and goes, so I'm going to try double lobes on each axle. If that doesn't work then a multi lobed cam and if that doesn't work then two sound cards.

 

Ron

That's what I was thinking... another sound card, possibly just a stand alone system, like a Trainsound or RailSounds Lite set.  It can just be track powered and not needed for horn / whistle / bell.  This would save not only space, but also duplicated electronics with features that will just be wasted.

 

Thanks,

Mario

Ok, I've tried every permutation I mentioned. Multi cam, different cams, and different wiring. With just the two lobe cam it gives perfect crisp 4 chuffs per driver revolution.

 

So, I'll get a lite sound card, as Mario suggested, to make the other truck work. Maybe I can mount a small speaker in the boiler for four of the eight chuffs. That would be sweet. 

 

You never know until you try something.

Still,,, nice!
