I put it to you, with the greatest respect (and knowing nothing of your fame in other fields of human endeavour), that fewer than two people will be interested in your secondary school essays on Macbeth a century hence... So I argue that the two cases are not comparable. Fair point but I know as a history teacher and amateur historian we know far more about, for example, Tutankhamun than we do about those who toiled away on a daily basis to build the goods and tomb he occupied and I would argue it is those who are more interesting than Tut for no other reason they are more like us than he is. Maybe a slightly more comparable frame of reference would be how many people spotted car number plates and models so you know what cars should be in the station forecourt on a wet Wednesday in August of 1957? Just as useful information, and just as likely to have passed into history without anyone knowing nor caring. If we had the chance to tell those who built said wagons we wanted to know their numbers, I suspect they (the builders) we regard us as slightly mad! 1 2 Link to comment Share on other sites More sharing options...
-missy- Posted July 31, 2021 Share Posted July 31, 2021 Hello. So Mk1, 2mm scale NG coupling hasn't really worked. The main problem is I assembled the body of the coupling before adding the loop wire, as a result I had to open out the pivot holes a little too much to allow the wire with the bends through the holes making the loop wire a bit too loose when in position. I also had to increase the size of the catch wire to 0.4mm as the 0.3mm wire was a little too floppy and tended to fall either sides of the catch support bit. In principle it should work but it needs a different approach. A huge thanks to Roger for the original design for this. Any thoughts? Julia. 4 5 1 Link to comment Share on other sites More sharing options...
Klaus ojo Posted July 31, 2021 Share Posted July 31, 2021 (edited) This is really looking great! It is a pity that it doesn´t work to your satisfaction- for just now... It is a bit looking as if the loop would only pivot on one side but that may be a matter of perspective of the photo. What do you think about a loop design allowing more side play for the pin/hook for tight curve radii. This could certainly be done with this elegant DG-like design, however, other designs of prototype couplings would give much more excuse for a bigger and more coarse loop design. I am pretty sure you will not really need my thoughts but I felt invited to tell them. (Personally for my choice of prototype I´d take an ordinary central buffer and a 3 link coupling on both sides. But not this year and probably not next.) best wishes... photo: HSB coupling: fido / buntbahn.de (at bing.com) Edited July 31, 2021 by Klaus ojo source 2 Link to comment Share on other sites More sharing options...
RMweb Premium Popular Post Ian Morgan Posted July 31, 2021 RMweb Premium Popular Post Share Posted July 31, 2021 (edited) I have now completed the second, and more complex, power pole for Freshwater. My photos of the real thing are not very clear, so there is a lot of guesswork and artistic licence here. Here is the best photo I have found And here is my interpretation using 2mm diameter brass rod, brass wire and L section. The transformer is from N Brass, but I did not get on with the etched insulators supplied with the 3 D print, so I replaced them with 12BA bolts. The other small insulators are wire-wound guitar strings, and the larger ones are from Shapeways. It will end up right at the front of the layout, so I need to complete some scenic work in the area before I can plant it in position.

I have a Raithby 8F etch from which I could take the plain smokebox ring as it's about the right size, but I've yet to decide whether to use it or try something else.

Your model is looking rather nice John Hi John, Have a look at my Princess instructions - basically one length of tube with a short length of the next size up tube at the firebox end so you get the cone shape for the boiler wrapper. You may need to add some shim round the short tube to get the right diameter at the firebox end. Its also worth trying to tapper the short tube towards the smokebox end so that the wrapper is in contact along all of the short tube, not just the front edge.

Simon Hi Simon, looks good so far. May be you know but just in case, its worth opening out the steam pipe holes before you fix the smokebox etc to the footplate as it makes fitting the steam pipe at the correct angle a lot easier. I found I had to file the hole at quite a sharp angle to get the pipe to fit inside the smokebox. Nigel Hunt 1 Link to comment Share on other sites More sharing options...

I make no promises it will be spot on (it's based on my interpretation of the available 8F boiler clothing drawings), but it's not far off. From memory if you are generous in cutting out so that the effective diameter produced is just a bit larger than the template then you'll get a better fit at the smokebox end. The Raithby 8F does have an etched smokebox, boiler and firebox, but its dimensions are different so a Raithby boiler can't be used as a straight swap for the cast one. That was my plan A!

RMweb Premium Nick Mitchell Posted August 1, 2021 RMweb Premium Share Posted August 1, 2021 I rolled up a Raithby etched 8F boiler barrel to see what it was like. That had been my Plan A (I think?) as well. It came out as a section of a true cone, which is not quite right. It needs to be oblique. The bottom of the boiler should be horizontal - it is quite noticeable in photos of 8Fs taken side-on, because the boiler bottom is just above the top of the frames. I think Peter Whitehead and David Eveleigh had an article in the Magazine many years ago about turning such a shape form solid brass for a Great Western engine. 1 Link to comment Share on other sites More sharing options...

An 8F boiler is pretty much identical to a Black 5 except being shorter. And as what you have as a casting for the 8F is a Black 5 boiler sliced up, I'm not totally clear how the ring would not fit it. Both smokeboxes are 5'4 3/4" in diameter.

Simon Well, if the turned ring is correct then it should be possible to remove a slice from the etched wrapper to reduce it to the correct diameter. I have a large bag containing leftovers of Balck 5/8F cast boilers and the smokeboxes have average diameters hovering around 11mm. So a little bit too large, I say average as they are not totally circular. But that is casting for you.

Chris We are talking at cross-purposes Chris. The front rings for the smokebox are etched. Your wrapper is the right size. The etched front ring is too large for the wrapper, but is intended to match the cast boiler. Simon Link to comment Share on other sites More sharing options...

I think Peter Whitehead and David Eveleigh had an article in the Magazine many years ago about turning such a shape form solid brass for a Great Western engine. iirc David turned a cone on the lathe and then bent the coned part around the headstock and then carefully sawed/parted it off at the correct positions relative to the diameter. (Turning a cone in the lathe is straightforward for any with a taper top slide who has a clue what they are doing, although the taper is not much.) When I attempted the same for myself I went about the turning in the same manner but fashioned a way of clamping the fustrum in the mill to finish the ends in the correct alignment. It seemed to me a much safer route than working with an out of balance workpiece in my small lathe. Link to comment Share on other sites More sharing options...
