| | Soni Honegger used a .50 caliber casing in his K-27. It was identical in principle to the one Jay posted, though the implementation was a bit different, of course. It worked well, though not as well as what I was hearing in that video. | |

I would have to assume that it is similar to these. I forget who posted these in the past on here. Anyway I copied them fo my files for later reference to try and build. There are a few that someone made the same design using a .45 cartridge.
I'll have to check out Bill's Although he does have the proper nozzle and petticoat exact from the Aster GS4 so I assume that would affect the draft a bit? Who knows....
This is a "Chuff Enhancer" by David Bailey built for his C-21 #361 (these are his photos). The curve in the pipe is to center the exhaust under the stack. Made from brass tubing; he was selling them via his website 2 or 3 years ago but they're no longers there. Similar principle to blowing across the top of a bottle and it works pretty well. I think David's shows it doesn't have to be all that complciated to work.
A few years ago I asked Larry Bangham if he'd ever worked on a way to improve a steamer's exhaust, like his whistles. He said he had for a few different locos but never written anything up. Interesting to hear how he did it.
Seeing and hearing The Bark Box at Diamondhead was interesting. It seemed a little too loud to me at DH, and the video clip seems the same. I think it needs some tuning and maybe a volume control. I definitely don't want it drowning out one of Bob Weltyk's whistles. 
Seems worth giving one a try. | | | |

| Chris , it sounds to me that you are knocking the barkboxes that you think will over power your Weltyk's whistle. I have heard many of these in person on different locomotives that also have Weltyk's whistles and these two products complement each other, they are like music to my ears. There is nothing like hearing a locomotive equipped with these products chuffing around the bend just like the full size locomotives and then hearing the beautiful blast of the whistle,and with steam coming out the stack, head and marker lights lit is just the icing on the cake. As for the bark box being to loud, remember, whistles and steam exhaust have the same amount of steam pressure from the boiler,just like full size locomotives. Do you have some sort of 1.20.3 scale volume measuring device? we should feel lucky that there are such ingenious people in this great hobby of ours that can conceive such clever little devices that make our hobby so much more enjoyable. Thank god for Bob Weltyk and his whistles and Chris and Richie's Cajun Barkbox chuff enhancers. Now all We need is for someone to come up with a realistic sounding bell that swings automatically.

Ferd:
You said, "...just like the full size", could say it is the real thing given the bark box's volume 
The tone and volume of sound depends on a number of factors beyond steam pressure, for example a whistle the resonator, aperature, etc.
A Bell? Very interesting and I'd love one too.
Bob Pope has shown how to do this on his great diesel. He actually mounted a real bell maybe 2.5" (maybe 3") in his diesel. I'm a little sketchy on the details of how it rings other than it is R/C controlled. It sounds really great. There is space in the rear portion of the tender behind the baffle plate of Accucraft's locos (K's and C-21, etc.) So there is a proven method and a place now all we need is for someone to do it and then write it up of start selling a setup, a module maybe with servo for a solenoid/plunger or cord to pull the ringer, that you install and connect to your R/C receiver.
Now, how to access the rear of the tender blocked by a baffle plate. Torry K. uses a torch in the center of the plate heating it until the side's solder joint breaks and it falls off leaving not a mark on the exterior paint. To still allow for a gas tank water bath, put the bell in a plastic or better metal (brass) open top box with the electronics. Or glue a metal or plastic baffle in place after adding the bell + electronics.
There you have your bell. Of course you pick a bell that is the largest that will fit in the tender. Seems to me the bell sound will resonate in the tender and be louder than if it were outside. So there is your method.
Bob Pope:
Where did you get your bell and how is it controlled on your desiel? | | | |

| Here is a Bark Box and a Weltyk's whistle in my K-27. Judge for yourself.
All I need is a bell and I'm figuring that out.

| That brings to mind a funny story: One of the guys in the Nashville club made the move to riding scale, and came by the club meeting one day pulling a trailer, on which sat his new 7.5" gauge steamer. It wasn't under steam, of course, so he couldn't blow the whistle, but he did grab the cord and ring the bell, which was about 6" diameter and mounted under the boiler, between the frames.
One of the kids in the club stuck his head so he could see the bell and called out "Wow, look at the big old dinger hanging down under there!" There were enough farmboys in the group that the remark got a huge laugh. | |

| So how did it work out did you have time to install the Bark Box yet?
I put one in a GS-4 about a week ago it sounded good. | |

| Dwight,
I don't know where the whistle drowning rumor came from, but it's not an issue. The bark box and whistle complement each other. Take a look at this:

| Carl, I've taken the liberty of editing part of your K27 Bark Box video and reposting it. I'm afraid my capture software has degraded the image, but I hope you'll like the sound and the motion of the cars.
Apart from selecting a clip, I've just made one teeny change ;-)
David England
PS I will delete it if you would prefer.

| Dave, Thanks for the try, but the video no longer sounds like the Bark Box actually sounds and neither does the whistle. Sigificant degridation was already present because the original was an analog video thaat I had to convert to digital to post it. I'd rather you delete your changes. Carl | |

| As requested, Carl, I've removed the edited video - thanks for sharing the original. I appreciate that you wanted to convey the actual sound of the model, and you are quite right that my version no longer does. That was actually the point of trying it. Although we cannot scale time as we live it, we can scale the appearance of time using a movie camera. That is how Hollywood can make a small model look like something big, and with a lot more inertia. By reducing the speed of the movie (one click in 'free' Windows software) the sounds and motion get a step closer to the full size.So much so that on some G1 models with good stack talk, the sound has been mistaken for dubbed-on full size sound.

| David,Thanks. For clarification of my reason, I was Richard's very first Bark Box customer and wanted to assist him with conveying the capability of the device. I notice that people are still watching with viewers already up to 2,163. However, I am interested in what software you are using to slow down the video as there are times I've wanted to do just that. Can you please enlighten me. Carl | |

| That is an excellent reason for wanting your videos to stay unmolested.
The speed change was done in Windows Movie Maker, which is part of Windows XP and Vista. (If your Vista won't run it, download WMM 2.6)
On the View Video Effects menu, drag the item "Slow Down, Half" onto your clip. This slows down the sway of leaves, coaches etc, drops the sound an octave, and makes everything look more solid than it is. Doing it twice, to quarter the speed, just loses the sound.
A better method is to record the movie at double the usual frame rate if your camera will do that, and play it back at normal rate.
Here is the video that an expert on these locomotives thought had been dubbed with full-size sound:
Apologies to those who have seen it before, and thanks to the maker for permission to post it.

| David, I am using Windows Movie Maker v 6, build 6001, which runs under Vista 64 bit. This version does not have a slowdown capability in video effects. I don't think I want to go back 4 versions just to get it. Thanks for the information. | |

It is there - I'm running the same version. Drag your clip into the storyboard and then select Clip--->Video-->Effects and scroll down....... | | | |
