Success at last,, cab forward single cam dual engine sounds

Ron,

So you used a single square cam on one axle to get the sound?  Along with the microswitch you posted earlier?

I did get a few of those switches Friday for my project.  Much better than messing with magnets, in my opinion.

Your CF sounds awesome.  My 'gears' are turning now...

TA I did and it works great. You'll have to fiddle with the contact of the cherry switch with the cam. I'll measure the square and let you know its size.

Excellent, thanks!

I know the Williams one will be different then the Rail King one I have, but could you post photos of the cam and it installed please?  I'm really thinking about using the GS4 sound set with mine now instead of the articulated set when I upgrade it to TMCC.

Excellent sound!... much better than the previous cam sounds. 

Ron, big THANK YOU for the videos--terrific project.

Suggestion:  Can you supply a link to one or more of your previous threads describing what you did for the sound, cam, etc.?  It will make it so much easier to understand and track the project.

Again, thanks for the videos.

Nice sound.

Ron...

Nailed it!

Thanks,

Mario

TA the square I used is 5/16ths. Just happen to have one close to the collars I had ground into cams.

I can't find the construction thread I started. It got moved.

So what I did I bought some small cherry switches made by Gilmore from an electronics store. These were packaged as micro switches. I've seen smaller.

I created a crude brass mount for the switch and mounted it to a tender truck to replace the reed switch. In the photos you can see I ground a model airplane wheel collar to an oblong shape which will work perfect for 4 chuffs per driver revolution.

To get 8 chuffs I had to go to a square that I found of roughly the same dimensions. t is a press fit on the wheel axle.

You will have to use a wheel puller to get a wheel off and then use a wrench socket as a mandrel to press the wheel back on. I used an 11/16ths socket.

I've included the two pictures and video I originally posted.

I'm curious.  On my Ipad, these videos play upside down.  I'm looking at the smokestack at the bottom of my screen!!?

What is up with that?

Something wrong with the I pad.

Pain in the membrane.

Hope you get it figured out.

Ron

Nice running steamer, great sound affect.  Creative problem solving. 

Nice job!

Finally rendered a video of the square cam and its effective chuff cutoff.
