Caley Jim Posted March 12, 2018 Share Posted March 12, 2018 Now, Stewart Hine built his own motor for that Small Prairie. That you might consider insane. Chris In those days there wasn't much option! If you couldn't shoehorn in a Minitrix or Tri-ang X500 you either built your own motor, tried to modify a continental N-gauge chassis or did without!

RMweb Gold 2mmMark Posted March 12, 2018 RMweb Gold Share Posted March 12, 2018 SECR coupled wheelbase 16'-6", 57xx wheelbase 15'-6" according to Wikipedia. The LMS Jinty has a 16'-6" wheelbase, but whether the rods are the same style is another matter. To be honest, the cost of a new etch is not significant, and a custom one can cover things like balance weights and bufferbeam overlays (depending how big the cut-out for the N gauge coupling is). The tender wheels should be do-able using the same process as the 4F. Unfortunately that project has been delayed due to Alan Smith having to spend a lot of time sorting out loco wheels, pcb sleepers and other products following the sad death of Bill Blackburn. Andy C Class has the same wheelbase as a Jinty but the rods are very slightly fishbellied. There's a good drawing in Model Railway News, December 1968. I have a scanned copy if required. This drawing seems to exaggerate the shape somewhat: A popular 2mm subject. It was the subject of an early 2mm whitemetal kit in the 1960s, Andrew Cox had the Jidenco(!) kit etched down from 4mm and Nick Tilston (N Brass) does a whitemetal/etched kit. Incidentally, I think it's a little bit cheeky to describe building a motor as "insane". At the time Stewart Hine built his 45XX in the early 1960s, it was the only option.

Mark The main difference is that the rods of a Jinty are fluted, whereas the C class are plain-fronted. If you actually tried, I'll accept your opinion on building your own motor. I did actually try to follow the instructions on the Small Prairie, and I'm sticking with insane. Chris Link to post Share on other sites More sharing options...
Mr chapman Posted March 12, 2018 Share Posted March 12, 2018 (edited) Some very useful replies here already I would assume then if it was just a case of them being plain fronted rather than the available fluted I could flood them with a tiny bit of solder and gently file back? Looking at the Farish EP in the latest CC mag the coupling rods look huge compared to 2mm. Those well tanks really are superb little models!

RMweb Gold Steven Draper Posted March 12, 2018 RMweb Gold Share Posted March 12, 2018 (edited) Looking at photos of the preserved C class, the coupling rods 'fishbellied' look is very very subtle and it doesn;t look like the OO gauge model they bothered ! I think it will be a very popular loco, I'm going to get at least one so a coupling rod and detailing etch would be very useful 8^)Will be placing an order for other bits later this week too - so hopefully not long and I can start making things in 2mm happen.

Looking at the Farish EP in the latest CC mag the coupling rods look huge compared to 2mm. Those well tanks really are superb little models!

I did actually try to follow the instructions on the Small Prairie, and I'm sticking with insane. Chris I attempted to cut down a Minitrix motor which wasn't successful. I did cut down a Fleischmann motor which went into the first Sentinel I built. That did work well. I don't really know why I did it when Tenshodos were already available. I expect it was a Sunday afternoon and I wanted to build it right now as I had most of the other bits I needed. Inherited from Denys Brownlee, I have a tin of bits which was going to become a model of Viking (IoMR no. 17). There's a couple of partially complete handbuilt coreless motors but the actual chassis is using a readymade tiny can motor which had just become available. Thankfully we now have lots of people out in the far east working in electric motor asylums. Link to post Share on other sites More sharing options...

RMweb Gold snitchthebudgie Posted March 13, 2018 RMweb Gold Share Posted March 13, 2018 I'm trying to decide whether to take the plunge into 2mm. I would start with a Wisbech & Upwell layout, using Farish O4 shunters with tram skirts. So my question is, what is the minimum amount of work on the Farish wheels needed to get them through 2mm points? I don't need full replacements, and cosmetics are not critical as the wheels are going to be hidden. Cheers, Jon Link to post Share on other sites More sharing options...

Take off the bottom plate to release the wheel sets. Send them off to the wheel turning service to get the flanges thinned and the wheels re-gauged. When you get them back, re-assemble, tweak the contacts a bit and you're ready to go. David Edited March 13, 2018 by Kylestrome Link to post Share on other sites More sharing options...

David Of course, I hope you are aware that the body of W&U 04s is not like the Farish ones, which represent later 04s. Different number of compartments on the hood, different front grille, different cab. I was going to do the same conversion but gave up on it. Someone has done a nice 3D-print of the skirted 04s, you can see it on another thread. Not sure if he is planning to offer it for sale though. http://www.rmweb.co.uk/community/index.php?/topic/8147-3d-printing-class-25-parts-also-class-2037-2mm-and-7mm-wagons-and-132-bogies/page-19 Chris Edited March 13, 2018 by Chris Higgs Link to post Share on other sites More sharing options...

Jim If I remember aright when I chatted to Stewart at the MRC exhibition at Central Hall neither the x500 or continental N gauge chassis existed. He had some bits and bits of clock gears from which he made the bits he needed. Wheels, Motors, Gears were all made by the modeller in those days. I think Stewart had the prairie in the showcase.

oily Posted March 14, 2018 Share Posted March 14, 2018 I used to have my locos and chassis under construction run themselves in on a length of track with a gap in the rail with a diode across the gap. Then a timer would reverse the current and the loco or chassis would run back. And so on all day and all night. Problem is now I have gone DCC the track is AC and the system doesn't work. So my question is, how can I set up a shuttle system with DCC? I have a Digitrax DCS51 controller and an even older ZTC system that was really great but rather bulky and now stored in the loft! Is it even possible without a massive amount of new electronics? Oli Link to post Share on other sites More sharing options...
RMweb Premium Ian Morgan Posted March 14, 2018 RMweb Premium Share Posted March 14, 2018 Not impossible, but you would probably need a PC running something like JMRI, and an interface to your DCC Command Station. Some sort of sensor at each end would be advisable too, although you could create a JMRI script that changed direction after a given time, and hope your loco does not speed up as it runs in.

Crosland Posted March 14, 2018 Share Posted March 14, 2018 A Raspberry-Pi would be a good "PC" and sensors could be connected to the GPIO pins. JMRI already supports this, I believe. A rolling road would be another option. Link to post Share on other sites More sharing options...

Could be a useful source of parts for converting the Farish body. There will be a scale difference as Allen's are to 1:152, although he may have an option for 1:148 scale. Building the complete body from the etch would be a gentle intro into etched kit assembly, it's not a complicated build. Mark Link to post Share on other sites More sharing options...

justin1985 Posted March 14, 2018 Share Posted March 14, 2018 Another part finished wagon that ended up with me was an LMS van (2-511). The blurb on the product page lists this as LMS van to diagrams D1808/D1812/D1830. I followed the listings on the project page and ordered chassis 2-332 (10ft 2 shoe per side) and the steel solebar conversion kit 2-337 (17'6"). I don't have any reference materials for the LMS to hand, but looking at the photos on Paul Bartlett's site, all of the LMS vans of this body style (with minimal strapping) and all of those listed as D1812 or D1830 are vacuum fitted with clasp brakes (4 shoes per side). There are some similar but different body style vans with unfitted 9' wheelbase chassis. All of these photos are survivors in the late 60s to 90s so I realise they might not be representative! I can't see any pictures labelled as D1808, or find any other reference to it on the internet. Could anyone with the LMS wagon books check whether there was indeed a 10ft unfitted/2 shoe per side brake version of this van body style? Or do I in fact have to use a different chassis if I want to get it right? Cheers Justin Link to post Share on other sites More sharing options...

Plus I like to get the bogie and tender wheels thoroughly run in too. And it always looks so much more authentic watching a new creation running up and down some track rather than sitting stationary, albeit with revolving drivers.

That said all the pictures appear to be fitted vehicles and the example running numbers don't differentiate between fitted and unfitted. Your alternative is to add a piece of diagonal strapping and use a 9ft unfitted underframe for D1832A. Contact me via PM if you need more info.
