Title: Steam locomotive driving wheels?

Hi all in 009 Society

I am the brand new member in this society. Until now I have built only Finnish

Welcome to the Society Petri.

First off I think you will find that the wheels sold by the 2 mm association will not work on 009 track.  The 2 mm association standards are fine scale - they use 9.42 mm gauge for a start -  with much finer wheel profiles than foround in 009 (and N gauge).  Whilst they could be used you would probably have to build your own fine scale track to go with them.  However their gears are not scale specific and could be useful to you.

One of the useful things when it comes to narrow gauge locos, particularly those built in the UK, is the use of outside frames and bearings with the wheels between the frames.  This means that one can use wheels sold for use in wagons, as the crankpin is mounted on the outside crank and not on the wheel.  I have often used wagon and carriage wheels designed for 4 mm scale standard gauge (i.e. OO and EM) and also those for 3 mm scale as in addition to costing less they are often available in the smaller diameters.  I usually re-use the axles too as all it takes is the cutting off of the pin point (coned) ends to turn them into paralell ones and then they usually need to be cut down again to get the right length for the narrow gauge.

I suspect that it is these types of wheels that Backwoods Miniatures use having hear that they were using wheels from Romford Wheels, but I do not know for certain.

However, if the locos that you wished to build models of have the frames inside the wheels then things are a little more dificult.  They may be available for 3 mm scale use (2 feet 4 inches to 3 feet diameter) but I can not think of a source of driving wheels in the 7-9 mm range with integral crank pins for N scale, unless one was to obtain them as spare parts from one of the bigger manufactureres (like Fleischmann and the rest)

As to gearboxes I have used those from Branchlines on my 12 mm gauge models.  I also have one fitted to an 009 loco that is being built but the gearbox needed some modification to get it to fit.  Gearboxes similar to those used by Branchlines are made by a company called Porter's Cap and may be available through Backwoods Miniatures.  I have also made my own gearboxes from bought gears, but it may be more cost effective to source metric 'Module' gears from mainland Europe rather than the imperial 'dp' type gears from the UK.

I thank you for your answers.

You are exactly right. The 2 mm standard wheel flange depth looks like be only 0,51 mm and tyre width 1,3 mm. This kind of wheel set is too fine for my FastTrack turnouts.

Unfortunately in Finland we do not have any steam locomotives with outside frames. I do not know why, but I think that the snow in winter times might be the reason for that.

Yesterday I found some addresses that might be useful all of you. The Polish company named RB-Model has the 8,9 mm diameter driving wheel for H0e steam locomotives. I also think that this might be suitable for one of my projects http://www.rbmodel.com/index.php?action=products&H0e=H0e-S780-9
Another company comes from Italy named Linea Model. They have different kinds of small gears and worms with metric module dimensions

Here might also be the useful gearbox made by the Polish company named Pojezdy. I have not yet used myself this item, but when I have some test results I will inform you. http://www.pojezdy.eu/eshop/78-gears-and-gear-kits
