cornamuse Posted January 21, 2015 Share Posted January 21, 2015 Like that a lot - very hard-working appearance. I don't suppose anyone has a picture of any of these tiny locos with tramway skirts? it would make life a lot easier as a build! cheers andy Link to post Share on other sites More sharing options...
RMweb Gold NeilHB Posted January 23, 2015 RMweb Gold Share Posted January 23, 2015 Andy, I think I have a set of drawings somewhere in my collection for the Great Eastern version of the piano tank - they had 2 skirted locos. Will see what I can find. Neil. Link to post Share on other sites More sharing options...
cornamuse Posted January 25, 2015 Share Posted January 25, 2015 Would be much appreciated, please! not having to couple the wheels would mean that not being able to set the quartering wouldn't matter - making a very free running, reliable mechanism - I have used the same technique with a diesel and the loco I use as my avatar. both run like they were using expensive mechanisms and chassis. slater's loco wheels would solve the problem completely, and let me couple them, and maybe even have outside mechanisms - but I don't want to spend £40 on a loco that has otherwise cost under £15 (including £8 for the wagon wheels!) alternative - anyone know of a cheap source of 0 gauge loco wheels? don't really want to re-gauge 00 ones, as that will be back into the same problems, with added inaccuracies cheers Andy Link to post Share on other sites More sharing options...
hartleymartin Posted January 27, 2015 Author Share Posted January 27, 2015 As far as I am concerned, it is worth every penny spent on good running gear. I'm willing to pay for slater's wheels, an etched gearbox and a good 40:1 or 54:1 gearset. Link to post Share on other sites More sharing options...

Guest Isambarduk Posted January 28, 2015 Share Posted January 28, 2015 "... and a good 40:1 or 54:1 gearset. " I agree with your earlier recommendations on wheels and gearbox but, in 7mm, 40:1 or 54:1 is a rather high ratio. It is not necessary for modern can motors, a lower ratio will be much more efficient and noticeably quieter. I can recommend Ultrascale gears; they are inexpensive and come in a huge range, the Nylatron (carbon-filled nylon) worm is self-lubricating and contributes to the quietness.See: www.ultrascale.com/eshop/products/CAT015#WWGS4 I would go for something in the 20:1 to 30:1 range. Do not be put off by their quoted delivery times, for their normal gear range it's by return post. I have used these gears as replacements for the conventional 40:1 steel worm + brass worm wheel that were supplied in some kits and they have transformed the loco performance.

David I'm after some super slow-running. I also have to use a Mashima 1824 in one loco - the Tower Models 14" barclay which is basically a huge lump of pewter which will out-haul almost anything else I've ever encountered. The only locomotive that it probably won't out-haul is the NSWGR AD60 class, which is a monstrous 4-8-4 + 4-8-4. I used to have an 1833 with a 40:1 gearset but I want it even slower. The 1824 will mean that I can get a small flywheel into the mechanism to compensate for the pick-up problems typical of an 0-4-0. Link to post Share on other sites More sharing options...
cornamuse Posted January 28, 2015 Share Posted January 28, 2015 oh I quite agree, but my current budget with a small child is just about £0 - maybe the cost of card, superglue, paint ... the card cutter was pricey, but a treat, and one that could be justified because it has already had a lot of use, and saved a lot of money and time - more than paid for itself already. I would love them, but saving up even for a £40 set of wheels? by the time I had the money, my small human would need new shoes or something. so, it is a necessity, not a preference! mind you, it would probably run better, which would be nice - maybe sometime I will afford it. the tramway drawings will allow me to do one using 3 hole wheels, and no running gear - I have built a couple like this, and the running qualities and reliability are excellent. it might be a bit out of era, but I think it will look ok! that said, the locos run fine. with clean track and very clean wheels and pick ups, they run slowly and smoothly ... until the wheels slip out of true for the quartering. I have tried superglue, but it doesn't hold well enough. you would genuinely think I had spent some money! it is fine for at home, but having had an exhibition invite, will they stand up to 2 days of running? hope that doesn't sound like a rant ...

hartleymartin Posted January 29, 2015 Author Share Posted January 29, 2015 With the side skirts of tram locomotives, I wouldn't even bother with coupling rods. I'd have a motor to one axle and maybe a chain or some cogs to the second axle. I would just use ordinary wagon wheels. I've been toying with the idea of building a Y6 on and off for a few years. I reckon that it would be worth building it in scale timber. The only drawings I have, though, are the ones from the 1960s when the Rev. W.V. Awdry built his!

hartleymartin Posted January 29, 2015 Author Share Posted January 29, 2015 When I originally posted this thread I thought that someone would have drawn up a card kit for a Y6! Link to post Share on other sites More sharing options...
cornamuse Posted January 29, 2015 Share Posted January 29, 2015 my photo is just that - wagon wheels, cheap drive, no connecting rods, card body, plasticard chassis, runs like it cost £200 I cheated on the bufferbeams, and used a set off a wagon kit - the one that had donated the wheels, I think. Here are the drawings for the body. Leave you to work out the rest for yourselves. You just layer up the sides like you would do for a coach. tram engine.pdf Link to post Share on other sites More sharing options...
RMweb Premium Dava Posted January 31, 2015 RMweb Premium Share Posted January 31, 2015 Thanks for the very well laid out Y6 card kit! It would be interesting to see a photo of your chassis & how you did this. The Rev Awdrey drawing is quite accurate, he was able to take the dimensions from the actual loco. One of my books has a GA drawing, ie you can see the engine & boiler detail as well but the exterior is not detailed. The Y6 which got away to Derby & Melbourne for war service & nearly survived has always interested me. Dava Link to post Share on other sites More sharing options...

RMweb Gold NeilHB Posted February 2, 2015 RMweb Gold Share Posted February 2, 2015 Andy, May have found you a source of cheap loco wheels - I think they are designed for diesel locos but as you are producing inserts for the wheel face this may not matter - looks like the wheels screw onto the axles: http://www.modelrailwayparts.com/wheels_0g-steel-loco.html Cheers, Neil Link to post Share on other sites More sharing options...
cornamuse Posted February 2, 2015 Share Posted February 2, 2015 Thank you, Neil! They look superb, will order a couple of sets and see what happens... Link to post Share on other sites More sharing options...
