thanks everyone. i am considering adding a sound effect that will be triggered when a chute is opened that sounds like rock or coal being dumped. I want to run the sound loud enough to almost drown out the actual sound of little rocks landing on styrene. does anyone know where I can get a good MP3 file and a device that will play it on a continuous loop until the gate is closed. what I plan on doing is adding a contact that will be closed when the gate starts to open, and will stay closed until the gate is fully shut. I will hide a speaker up in the roof that will go over the hopper cars so it sounds like the sound is coming from the cars. I may have three speakers spread across the top inside of the roof.

Anyone out there have any experience with this I would love to hear, thanks

I've looked at (but not bought) players that start when power comes on. But I don't know start-up time - you want the sound to start as soon as the gate opens.

You might be able to lift the sound off Youtube videos. I'm sure there is something out there with a dumping coal sound.

I've used this for downloading some music. Note that by clicking the share button on the video you can designate a starting time, so you don't need to download the whole soundtrack.

thanks for those links. the hard part is finding the right sound. I looked at a lot of dump trucks dumping and there was either too much truck noise or the material dumping did not sound correct. I looked at loading coal into rail cars and it had the same results. I'll add the ability to have the recording play and keep searching, maybe some day I will find the right sound.

in the mean time I am working on the controls for the tipple. The plan was to use slide pots to simulate pulling on the levers of the prototype. I could not find slide pots with return springs so I pickup up the smallest return springs I could find locally. I designed a plate to hold all eight slide pots, set 1" apart. I designed a sliding plate that would go between the slide pot and the mounting plate, this plate will have a hook on the end for the return spring to pull on. the slide pots will snap in so there are no screws to be in the way of the return spring. the upper part of the plate is longer than I would have liked but I needed the distance for the springs, I will paint and decal the front of the plant, maybe I will find I need to put a set of operating instructions for the tipple in the open space above the slides and I will be glad it was there.

all parts are being printed and I will post photos of the finished products, if all goes well maybe tonight or tomorrow.

here is the design.

thanks Chris, that might work

18:10 of this one may work also. i am hoping to find one that is long enough to make sure it is longer than I will need it so it won't end before i close the gate

Would it be possible to have a loop that runs continuously and have the electronics connected to one of the speaker wires?

i am giving the sound thing a rest, i have watched too many videos of dump trucks. i will provide the ability to add the sound but I am moving on to other things for a while.

the tipple is moving along fine. it seems that there are days that look like nothing is getting done, then there are these big spurts where it actually is starting to look like something.

recently i have added in more ground goop around the bents. the color is off but it will all be covered. the ground around the higher elevations will be sand and about from the bin area down will mostly black coal dust. the goop is thick and it takes a while to dry.

i printed all the parts for the control board but...i didn't like it once it was finished. it all worked fine but it was way too big. i designed a smaller panel and I will show my plans for that when it is all assembled.

I designed and printed some parts for the wires to pass through the back wall of the coal bin rather than up and over it. parts turn down on the inside so the coal can't leak out of the bin.

I started on the removable roof and added sides to the coal bin shed. I made a mistake on the sides and did not extend them far enough back. I assumed the side walls of the shed extended back as far back as the bin but they actually go farther back, so I will have to add some more boards and alter the back of the roof, good thing I ran out of wood and never glued the rear roof section in place, must have been divine intervention.

the roof is working out well. I am bracing it up more than the prototype, it will need to be durable and it will not be able to be seen. One thing I a doing on this structure that is working out better than i had hoped is using small magnets to hold things in place. I used these magnets to hold the front wall in place and now to hold the roof down tight. I drilled shallow holes in the wood and just push the magnets in. the only thing to remember when installing them is to make sure they attract each other. I guess to make it easier I could have just used steel washers on one piece, I used two magnets, one in each piece, they have a nice "snap" when the parts go together.

here is how I am running the servo cables out the back.






this is one of the small magnets I am using, they are very powerful, I got them from Amazon.


this tipple is getting huge, here is a hopper and a man for size.


progress so far

Making more progress. I got all the wiring done and the slide pots installed in the control panel. I am going to make a temporary base for the panel until I get the layout started because I am undecided how I want the panel orientated on the layout. I figure after I get the layout up I will know if I want the panel vertical and operate the slides with my thumb, or have the panel at an angle off horizontal and operate the slides with my fingers. my thoughts are to have it at or near vertical and use my thumb on my left hand. A vertical panel will not stick out in the aisle. actually, a recessed vertical panel with an overhead light above the panel sounds like a good idea. I will post photos of the panel once the base is done.

with the wiring all done I was testing all the gates. while testing one of the solder joints I had on the ends of the gate rods broke, it was then I decided on a stronger way to make that joint. I spent an entire night building new and stronger tie-rod ends for and switched all eight rods over. I am glad i found this flaw now, even though I did make the front panel that covers the servos removable for service I still don't ever want to have to service them, so taking the time to make all the parts more heavy duty will hopefully make it so I never have to get to them.

with all the wiring and test done I am pressing on to start to add the more fragile details parts. I just printed all the jigs to start to construct the faux gate arms and all the arm supports and car shed roof. I also modified the truck dock bridge to now be mounted with magnets. The magnets are working out excellent and I plan to use them to also attach the car shed structure so it is also removable for service.

I added yet another layer of soil and coal under the structure. I think maybe just one more should do the trick, then I will add coal dust to all the ground cover and the structure under the bin. I painted the coal spill slot between track and the bin black and I am happy that it really hides it well, next I will paint the outer slot and the braces under the plywood base.

I had to adjust the side the coal bin shed, the prototype sides when back farther than I had made mine. the modifications also included removing all the bracing under the rear of the roof so I could move it back as well. I hope I am done taking backward steps.



the black painted slot is hard to see now.

now that RRL is back up and running I thought I would give another update to the strip tipple project. I really thought I was done taking two steps forward and one step back but I am not. what keeps happening is that I look at a photo, build what I think I see, the take a photo of the model and compare it to the prototype photo and then see how the two match up. it seems tha almost every time I do that I see something that looked right when i was building it but looked wrong in the photo.

my latest issue is the track location is off. the track really should be closer to the tipple then I have it. the difficult part I have is that I believe the material I am using for coal goes out farther past the end of the chute then the prototype did, therefor I need to have my car a little farther away from the end of the chute (more make the chutes shorter) then the prototype. Either way I have my track in the wrong spot, it is too far away and the coal splash boards do not go over the car in the correct spot and do not function like the prototype. I have pulled the rails and removed the ties and started testing with a piece of flex track. I did find a location for the track that it operates best at, however it is about 12" farther away from the tipple than what I believe the prototype was. one more test I want to do is to test the tipple with a different coal material and see if it dispenses differently than my current material. I switched from real coal to black rock for dust control reasons but I have been questioning if I should return back to real coal again, mostly because I like that it is a more flat black color, and I love the smell of it.

since I have decided to remove the track I am going to take this time to use my real Manns Creek ties on the new track. some of you may remember that back in 2014 I visited Babcock State Park and walked the narrow gauge trail. there are still some of the original ties from the Manns Creek in the trail. I took a sliver of wood off of a tie and brought it home, then got the idea to make an On3 tie from the sliver of wood. I have decided that an appropriate place to use these ties would be at this locations on the new layout, because this is the most prototypical model I will build that will have the most prototypically located track. i will need 36-40 ties to fill this space, so far I have cut 12 ties by hand. the only issue I will have is that I think I only have enough material to make about 25 ties, so if anyone lives next to Clifftop and wants to go get me another sliver I will pay the postage and the park fee, but I need it sooner rather than later.

here is a photo of the piece of wood I picked and some soil I scooped up. you can see the small tie I made from the real tie. I have a small bag of soil that I will also apply around the track so I will have real MC soil around real MC ties.


I also have one more issue to solve with the servos. The issue I am having is that if a piece of coal gets stuck under the door the servo will continue to try and keep pushing the gate down, there is no stall on it. when the servo is not able to return to its closed position it makes a noise, and I am sure it is not good for the servo. it is easy enough to just back off the gate and the noise stops, but I plan on running spring returns and I need the gate to close all the way each time. I see two solutions, the first would be a spring in the gate rod that allows some give in the gate, the second would be to not have the gate close all the way down tight. the will not flow from the gate if it has a small gap at the bottom so the solution may just be as easy as adjusting the length of the actuator arm. However I am going to set to see how much spring force the servo can take and maybe design a sprung actuator arm.

here is a video that shows three cars being loaded with 6 of the 8 gates. in the video i almost opened one of the gates that was located between two cars, that would have been a mess for sure. it almost makes me want to design a new control panel that has safety latches on those two gates that are between the cars, that way it will take effort to make what is now an easy mistake. those two gates will only be used when the bin gets too empty to fill from the other 6, then the cut of cars will be pulled forward and those gates used until the tipple is empty.

here are some photos of where the tipple was at before I tore out the track.

I'm impressed by your progress on the working coal dock.
