As promised heres the HOWES sound chipped Robinson, Youtube and the rolling road doesn't do it justice but i'm sure you'll agree it sounds damn good

 

http://www.youtube.com/watch?v=iq7DPvmGJbk

 

functions are as follows:

 

F0 Lights on/off. not applicable on this model

F1 Sound on off

F2 Long whistle, continues sounding until F2 is pressed again.

F3 Short whistle

F4 Buffer up

F5 Coupling up

F6 Injectors

F7 Draincocks

F8 Safety valves

F9 Carriage Door slam

F10 Guards Whistle

F11 Buffer clashing on wagons. 8 seconds

F12 Wheel/sleeper groan

F13 Shunt Mode, Half speed

F14 Accel Decel override

F15 Aux1

 

The random fireman sound has been mapped to activate Aux 2 within the soundfile, so if a firebox LED is fitted by the user it will flicker when the fireman sound is on Aux 1 is left free for operator use.

Haha sounds just like trainsim, I'm not sure if that's a good or bad thing really, doesn't sound too much like the real thing though.

 

In other news, more pics of 63601 at Wenchford,

I wonder if there has been any communication with Bachmann to ascertain their view on the slidebar/cylinder issue. It does seem rather counterproductive to me to pay £125 for a RTR loco then have to start taking it to bits and packing, cutting etc. to make it look acceptable, surely someone should be puting some pressure on Bachmann. I know upsetting the manufacturers is frowned upon but this loco has been a long time coming and it is still not right, I'm glad I am in the market for a GWR version perhaps the tooling will be sorted by then!

The thought has occurred to me that a letter to Bachmann is in order. They could rectify the parts pretty easily for correct appearance on future models, and offer replacement components for those of us happy popping bits on and off. I am now absolutely certain that there is no technical issue requiring the chassis to be incorrect in this respect to get the model round set track curves, this is an error that has crept in when the parts were designed.

big Jim I must say a big thank you for putting the sound Vid up. That is very worth while in that I think I might order a chip from Howes when the currency stops yo yo'ing (the Aussie dollar is good at the moment against the pound but it has been better!I think that Brian has done a great job on the sound. I can hear the same set of sounds for the coupling's and clanking as the super D though I don't mind tha!.

 

Great and thanks again

quick reply from bryan regards the above comments:

 

The clanking is different to the Super D , similar but the 04 has 4

distinctive sounds as the 04 squeaks a bit on coasting, the video doesnt bring it out as when heard live. as for the running sound, if you run the loco slowly before you open up and it starts to bark, if it is notched back to coasting and then gently forward it chuffs quietly like in a yard without draincocks,notching back and fore can give a nice degree of light working, then you can open her up to full bark as on the vid. It needs to be driven, and practice will bring out the best in it.

As for the comment on the train sim comparison, having never looked at train sim so I cant comment, I only use material I have recorded (in this occasion bryan recorded it from the preserved 04, so can't see how it doesn't sound like the real thing!!).

 

I have to say that a steam loco decoder will never be able to replicate all the variances and subtleties of sound that the real thing makes but what it can do is to add the extra dimension that makes the addition of sound worthwhile for those that want it,

I have 2 or 3 different chuffing sounds I recorded at the GC but when I tried to fit them all together it sounded such a hotch potch so I opted for variance of sound levels instead so the sound and pitch of the chuff always flows.

 

 

Couple of things to note, The loco tender wiring is the same as for the Super D, I see that someone has already experienced a similar problem on the 04 where the decoder burnt out, check there is no short circuit on the small PCB under the footplate, what I do is run a blade between the joints firstly then I fit a standard 21 pin decoder to test the loco , this way will save you possibly losing an expensive sound decoder, if the model causes the fault it is not really a warranty issue!!. secondly I cut the caps off the motor as the loco ran a bit jerky although I dare say it might have been in need of further running in, I left the 2 chokes in situ and so far the loco has performed ok. the latter is a matter for the individual, Hope this is of some help.

Glad to hear the YouTube example. I noted that as the model ran faster it 'overtook' the sound, in otherwrods the wheels were revolving faster than the sound track. No doubt this is because the real loco never went above say 35mph while recording the sound. This should induce some form of control over modellers who think 04's darted about all over the place when in fact they were plodders. The short-burst whistle is just as I remember it on the D11's leaving Manchester Central!

hey lads, Pop down the railway to checking my turns, here is a picture of the crosshead and slide bar below of the O4, also the sound chip O4, personally, it don't sound right, sorry don't want to sound rude, it might be that i can't hear it.

I have not gone down the sound route yet because I cannot reconcile the 'tinny' sound whatever the loco. But that said Big Jim makes a valid point in that he says that it adds another dimension to the locos on the layout. I had not thought of it like that and maybe can accept the limitations of steam sound as long as they are put into the perspective that Jim states. I thought the recording was pretty good for the O4 but I doubt it would have run that fast very often unless it was down hill with a following wind!

Good news. Further on the slide bar bracket. There are no holes to locate the slide bar ends, they just go in either end of the vertical aperture in the bracket. So you just fill the bottom with a spot of araldite, and slot upwards a little at the top. So the steps stay in the right position under footplate, and the mounting bar location is unchanged, no hacking parts in a major way required. Now I know how to do this it is a very quick and easy job: 10 minutes to dismantle and alter, 24hrs for the araldite to go off, 10 minutes to reassemble. Requires a 3mm across flats spanner to undo the crankpin bolt, or an Allen key head with the right size socket, or carefully used pliers while no-one is looking. blink.gif

Again thanks are in order Big Jim and to Brian at Howes. I agree with the thought on the recording and the different clanks. I think the problem that I had in distinguishing the "clanks" is to do with the recording on another camera and then what ever you tube does to it! That way the sound always gets changed slightly in that it is a recording of a recording then compressed then un compressed etc. I am still keen to get a chip from Brian. As an aside, is the speaker fixed down with the black tack? I ask as my Super D of which I am so impressed by when first installed "dry" changed and became better when the speacker body was "filled" around the edges with "bluetac" teh sound was more defined and a bit louder. It reminded me of all the bits of year 11 Physics I had tried to forget :rolleyes: .

 

Another aside is the speaker a long oblong or a round? Then a Bass enhanced or not?

 

Sorry about all the questions it is just a way for me to order the right one from Brian in the long run?

reply from bryan:

 

I used the standard 23 mil speaker is in its chamber, there are 6 raised splashers in the tender floor which prevent straight fixing as in the Super D, there are predrilled holes in the floor for the sound to escape.

The removeable metal coal fillet which serves nicely as a weight, when removed exposes the channel for the coal as in the prototype, as the decoder does not allow for an easy speaker fit I cut the shute away inside to provide a flat position so I could glue the chamber base to it. the sound projects down through the holes in the tender floor, it also resonates in the tender but the overall sound seems fine.

Replacing the metal coal weight then covers the area I cut away, job done.

I am sure there are other ways people will employ but this was the simplest one for me

Thankyou Jim, I find the sound to be as good as any available in 00 British steam these days, the whistles are very nice, and low-to-average speeds quite nice albeit hard to reproduce a loco in full throat. The drifting noises and chuffing when throttle re-applired are excellent in my view.

Just been working on one of my GCR 8K's, the livery is now fully applied, a little more interesting than the plain LNER livery it came in! I have just got the change the saftey valve to a different type in the future and move the step and a few other alterations to make it 100% accurate.

This loco carries the later tender badge but in Yeadons it is shown with the early badge in 1964 after withdrawal. Did it get a tender swap late on or has it only carried the later type since preservation.

In preservation she carried early crest until someone paid forlater crests which is how she is now. Most liely if she had only carried early crests a different number would be on the later crested model.

Rails now have the late crest on at £89.99

 

Hattons usually raise the price of new locos after a few days, especially if they are hot sellers. The O4 never budged from the £100.00 mark, makes me think maybe they aren't selling quite as fast as had been hoped. Maybe it's just summer and everyone's planning holidays, maybe there's a psychological barrier when you hit the triple digits... mellow.gif

I don't know Pete. I wasn't going to bother with the O4, not being seen in Scotland after 1944, but that's got my attention...!

have you got facebook blocked on your machine? all my photos are hosted via their server, also you'll see it isn't actually any O4/1 anymore, it's an 8K :P

Yes, I was quite tempted also. Still am! cool.gif

 

I will shortly have to explain to SWMBO why a rather large green and yellow centipede is at our doorstep though. I've been telling her I'm reformed, that I've changed my ways. wink.gif
