Hello All

Has the society or anybody else done a 12" to the  1ft conversion table to gauge 3 , millimeters to inch / ft ? M.R.J. did some years ago for the smaller scales , But as they struggle to addmit the existance of O gauge I am not going through my back numbers to see if they did gauge 3

Hi John,

Well, we have just introduced a Society 'Scale' rule - it shows scale feet (up to 25') - with 1" divisions and costs 11 pounds. Other than that a spreadsheet will give you any range of scale conversion table you want pretty quickly.

Gents,

No, MRJ never did a G3 Convertion Table, but I have produced my own on an Excel Spreadsheet. I don't know how to distribute it via the Forum, but you can have for inclusion on the G3 Web Site if required. I have already sent a copy direct to John.

Derek,

If you send me the file to webmaster@gauge3.org.uk
I will arrange for it to be downloadable.

Regards,
John.
My fellow Members, ask not what your Society can do for you, ask what you can do for your Society.

I have just joined this forum so please excuse a number of comments

Scales; The scale ruler seems a good idea but as a matteer of curiosity what scale factor does it actually use.

Form Tool; An excellent idea. Also possibly a gauge as sold by NMRA which has various critical dimensions on it such as wheel back to back dimensions etc.

New Model; Someone mentioned a SCR 'C'Class as an appropriate loco. The Association has wheel patterns and cylinders sets for this loco and the drawings from Mr Downs are well drawn and complete. GRS do a lot of the external detail.
This seems to be a loco that would benefit from a new boiler for gas firing. I would suggest dual flue hedghog type or radiant heater.
Otherwise a very pretty loco.

Standard Parts:  Could agree more - its what Greenly et al did many years ago

regards
Christopher

The scale used is 1:22.6 -I have one of the Original Rules with the "slight numeric problem"...

A form cutter may be useful at the smaller scales but to be honest, it would have to made from T/C brazed onto a length of tool steel bar -far simpler to use a standard T/C tool bit and a compound slide.

The society does sell various gauges... However, I for one would not welcome Mr Stanley Ames and his N.M.R.A. anywhere near Gauge 3.

"The Venture" will be a kit of parts to build one of 5(?) types of loco. The SECR does still get "a look in" with the O1 loco though. Although I have not seen any of the plans for "The Venture", from the person involved in its design, I would imagine it has a JTvR type "C" boiler, and this would be a single cylinder with slip eccentric valve gear.

Having built a "porcupine" boiler, I would say that this type is more suited to the individual builder -than commercial production. The time taken to produce quills and seat them in the barrel pushes the time envelope badly. I was doing really well and I fitted 63 quills in a day... I also agree with current theories that the steam raising effect of a porcupine boiler, is more to do with the large number of nucleation points provided by the quills -rather than the amount of heat transferred into the water by them.

Though of the day from the bunker, in view of the weather, we need a simple snow plough design. Ideally an independent vehicle, but without rthe nasty curved vertical wedge all to many designs seem to have. Any suggestions of suitable prototypes?   :

Yes!

The Meyer snow plough as built by SLM for the swiss electric lines. This was steam powered and had a separate steam driven snow cutter and blower.

I photographed an NER plough under restorartion at the NRM in 1999 - construction looks to be fairly simple. If I can work out how post pictures here, I'll do it, otherwise e-mail it to John. I also have several other pictures of NER snowploughs and a drawing of the MR Hellifield snowplough if anyone's interested. Ted

Ralph,

I know you like the weird and wonderful, but a working steam-driven snow cutter and blower?  I dare you!

Mike,

(There is a reason that I have a set of plans for this baby.....)

The bodywork was wood and it was varnished and waxed to a high polish!!!
