I am currently building a couple of G gauge 2-6-0’s and would like to install a cam early for possible sound later. Is there a generic cam that can be install without knowing exactly what system will be used later?
Thanks

Hi Ron.
I don’t know about G gauge. Never heard of it. If you mean #1 gauge 45mm then read on.
In Large Scale the most common method of timing for a chuff will be to use small magnets on a drive wheel and a reed switch.
I have also seen opto sensors that read the gaps on alternate Black and White strips.
I guess it would be possible to fabricate a type of cam as used in the smaller scales.
Hi Tony,
Thanks for the response and sorry for the mistake, I thought that would have seen past it and known that I should have written G SCALE.
I stumbled into the answer to my question today on the internet also.

A search of Ebay and I have about two lifetimes of cam parts on the way.
Thanks again,

Hi Ron,
As a generic term “G” scale is wrong too.
“G” scale is specifically 1:22.5 scale.
Simply describing the plethora of scales that run on #1 gauge (45mm) track as Large Scale (LS) makes much more sense. That way there is way less confusion between what is actually “G” scale and what is lumped into one all embracing term.
Soundtraxx makes a cam for exhaust sync, and so does Grizzly Mountain Engineering http://www.g-m-e.com/splitcam.html

And don’t worry about Tony. We ignore him when somebody mentions “G.”
Gotta keep banging that drum.
Might as well get em to learn the correct terminology at every opportunity.
And why do I call this stuff GOOFY GAUGE ? It’s the best description that I know of and I’m unanimous in that. Slocum said that if you know what I mean ???
Was that Mrs Slocum?
If so she was always worried about her P’s and Q’s.
An in joke for us Brits.
Why Tony, I see you have heard of " Are you being served ? " Her and the pussy !!! Really funny bunch. Re runs here everyday around noon but just one show a day… BBC did have some great comedy shows. Fawlty Towers was another favorite. I actually first saw those while working in South Africa many years ago…Lesotho and Swaziland…Meet a few Brits there. Strange lot and talked rather funny. hehe ! They did know how to drink but were lousy poker players which was to my benefit. (grinning)
Cheers,
What’s the one that used to be on public television. (They took it off the air in my town quite a while ago.)
Had the three old geezers that always got into trouble in their small village. “Days of Wine” or sumppin like that. I liked that one, since my mother is British, I could relate to it.

We still get it here, but I like “Last of the Summer Wine” better!

Tony, 
Of course those who know what better standards are would refer to 1:22.5 on 45mm track as IIm (2m).

It’s that stiff upper lip!
TonyWalsham said:Oh, well. I'll just consider that Tony's been upside down too long...:D Many now consider "G" Scale to refer to 1:29, with 1:32 being #1, 1:22.5 being IIm, and 1:20.3 as "F" scale. Or, at least that's the way we call it in our neck of the boondocks...:D I call all of it Geezer Guage....:lol:

Hello Warren.
Many of the manufacturers use “G” scale as an all encompassing way of generalising the myriad of scales which would best be referred to as Large Scale “LS”.
After all, as I understand it “G” scale is specifically 1:22.5 (2m).
As far as I am aware 1:29 scale is not the same as the correct 1:32 scale for 45 mm gauge track. No matter how much Mr Polk and his ilk would love for it to be accepted.
Just as well really the Brits and Europeans insist on proper scale models, as otherwise they would be having an incorrectly scaled Class 66 shoved down their throats.
Sure the manufacturer has changed from a Gung Ho “we’ll do it for everywhere including the USA” to a more circumspect “we are just making it for Bachmann UK”. I’ll eat my words in public if the thing ever appears let alone sells in numbers to warrant production.
But what the hey. It is their money not mine.
Personally I don’t care a fig about scale.
Proper scale models may not have the “WOW” factor of the OOS stuff but at least they will have a chance of maximising the customer base by attracting scale modellers as well as the Toy Train brigade.
Not everyone is impressed by the “WOW” factor.
The Philistines can say and do what they like when it comes to scale.
I prefer to use the correct terminology that has been around for a long time.
It ain’t broke boyo. So why do we need to fix it?
The problem is multiplied when you have “associations” trying to set standards and nobody seems to be on the same page. The NMRA is trying to screw it up worse. There is the G1m bunch that’s got different ideas…and of course the manufacturers who mucked it up to begin with. I do agree that Lewis & Co. should have just produced the models in 1:32 to begin with. Now, about couplers… :mad:
I’ve watched the thread at Aristo about the Class 66… 
What a cluster &*^% worth of useless explanations. Since Lewis is planning to market an American version of the European container cars, I was assuming that the Class 66 would be 1:29. It sounds like you have heard otherwise. I must have missed something and my guess is that everyone else at the Aristo forum did too.

Warren,
Re the 66 class.
You need to understand what the average Brit/European modeller really wants. Whilst some in Europe say bring on the 1:29 Class 66, I am willing to bet the majority do not want it unless it was the proper 1:32 scale.
The participants at the AC forum are only hearing what they are told by the “boss man”.
Whilst Mr Polk is “offering” illumination on the Class 66 for the British/European market, perhaps he can explain how soon it will be before the British Market can once again get the trackside TE?
Oh! and whilst he is at it, what happened to the 27 Mhz “daughter” board that was promised when the 75Mhz first came out so that it would not be necessary to buy completely new systems?
The 75 Mhz onboard was to “improve” the performance of a perfectly good 27 Mhz on board system. Sort of “It ain’t broke - so we had better fix it”.
Still no 27 Mhz “daughter” board and now no 75 Mhz on board either.
Very strange.
I am not complaining mind.
With 1:29 you have a narrow gauge, sort of.
With 1:32 you have a wide gauge, sort of.
Now matter how you slice it, neither is true to gauge/scale. Do the math.
1:32 is just a bit bigger than O scale, and 1:29 is 3 times bigger than HO. How’s that again? I think I missed sumpin.
