RMweb Premium 47137 Posted January 11, 2020 RMweb Premium Share Posted January 11, 2020 (edited) This post is simply a collation of chassis details, intended to help people making their models in 3.5 mm scale. I have included 00 and H0 scale donors which I have used in my own models, other models I have to hand which look like they might be useful one day, and contributions from other members of the RMweb. I have omitted models which looked to me as though they ought to work with British outline H0 (like the Model Rail Sentinel) but which turned out to be too wide or tall, and too difficult to alter. I expect there are other candidates, perhaps the Hornby Peckett or the Hornby L&Y pug, and I'm happy to revise the table to add other models or put right the almost inevitable mistakes. - Richard.

rue_d_etropal Posted January 12, 2020 Share Posted January 12, 2020 a good start. Quite a few others. Bachmann GE70 chassis , fits my Ford. The GE44 is probably also useful, and the GE45 (if you can find one) is one loco that ran in Britain. Then there is the Liliput fireless locos, in particular the 0-4-0, which does not look out of place on British layouts, and the motor/chassis is slim enough to fit in British HO bodies(I haveone in my GWR steam railmotor). Unfortunately the 0-6-0 version has a bulky motor fitted, making it difficult for smaller British locos. The Model Rail tram loco could probably be useful, but like the new Bachmann J72 is a bit pricey if all you want is the chassis. The main difficulty is not wheelbase etc but motor size. Even the L&Y 0-4-0 tank loco has this problem for some small locos. It only just fitted my L&y steam railmotor. Tender locos present less of a problem as tender drive is an option . If a r2r bogie is not suitabe I am sure Mark at Locos n Stuff can supply a bespoke 3D printed one. 1 1 Link to post Share on other sites More sharing options...
Philou Posted January 12, 2020 Share Posted January 12, 2020 Pssssssst ............. if anyone is interested, over on Catawiki, there's what looks like an H0 Class 08 diesel shunter in NS colours made by Roco under bid at 45€ at the moment. To save you trawling all the pages, here's a link: https://www.catawiki.eu/l/33524149-roco-h0-43471-locomotive-diesel-serie-5-600-bakkie-hippel-en-couleurs-vertes-ns Cheers, Philip 1 Link to post Share on other sites More sharing options...

If a r2r bogie is not suitabe I am sure Mark at Locos n Stuff can supply a bespoke 3D printed one. It is sensible to include wheelbase information so people can judge the suitability of a chassis before buying a model. I've omitted the Model Rail tram because the wheels are 8-spoke and a bit too distinctive for general use. However the outside cylinders are commendably slim so I'll see if I can measure a friend's model. It is important with these to get a version without side skirts. The versions with skirts omit some of the valve gear, not enough room to fit everything in even in 00. The GE70 chassis should go into the table - have anyone got the dimensions to hand? The Lima 00 Deltic ought to go in too because the bogies are H0 for the class 37 or 50. If anyone can think of other candidates do post them here or send me a PM. I will update the table next weekend. - Richard. Link to post Share on other sites More sharing options...

RMweb Premium 47137 Posted January 17, 2020 Author RMweb Premium Share Posted January 17, 2020 I've updated the table, thank you everyone for the suggestions so far. If I believe the press release published by Rails of Sheffield, their forthcoming Terrier offers the possibility of a compensated six-coupled chassis. Looks good to me. - Richard.

RMweb Premium 47137 Posted January 22, 2020 Author RMweb Premium Share Posted January 22, 2020 I think it would be worthwhile to add chassis kits where we know they give us the wheelbase for a specific prototype, and we can be reasonably confident (if not convinced) the motor and gearbox will fit inside a 1:87 model. For example, I have a fold-up chassis for a 4mm scale Ruston and Hornsby 48DS. Wheelbase is 21 mm, exactly the 6 feet of a BR class 02. This chassis was designed to build up with one driven axle (making a 1A so to speak) but if you added side rods it would become an 0-4-0. Maybe we know of some others? - Richard.

RMweb Gold Joseph_Pestell Posted January 22, 2020 RMweb Gold Share Posted January 22, 2020 This is a good initiative. But some of them (recent 00 locos) seem like a rather expensive way to go about it. If we know that there is a small market (as few as 20) for a particular chassis, it should be possible to do it more cheaply by etching the frames and sourcing suitable wheels.

Well - if a particular route seems expensive, there is no need to follow it. This is for the modeller to decide. The topic heading I chose is "Useful Chassis for British H0 Loco Projects" and I think this defines the purpose of the topic nicely: what is possible using what is already out there. Anyone is free to design and etch their own chassis, and if they make it available for sale to the general public it can go into the table as a kit. A loco chassis might not get enough customers - a coach bogie with internal bearings and able to accept dummy sideframes might be a better bet to attract enough customers. - Richard. 1 Link to post Share on other sites More sharing options...

Coach bogies would certainly be useful. And as you say, numbers needed would be rather greater which helps amortise the development costs. Allen Doherty at Worsley may even have artwork already which could be easily adapted (re-scaled) if necessary. I think he even has some already for HO. As I thought, Worsley Works already has 8'6" bogie frames available, the most common dimension. Just need someone to make a master for the dummy sideframes and get them cast: white metal or resin. Or newer tech: CNC milled or 3D printed. Edited January 22, 2020 by Joseph_Pestell Add 1 Link to post Share on other sites More sharing options...

I have done some bogies myself, namely Gresley ones, but have tended to find drawings for bogies are not so easy to find. I have been thinking about loco chassis, as I have not been as impressed about the new J72 one as I hoped(that boiler base in particular),but it still might be best option for tank locos, when price comes down. For tender locos I would put motr in tender and use a dummy chassis inloco, and I don't think it would be that difficult to 3D print, but it would be basic. Just need to confirm size of holes fo axles/bearings. Bearings would be need as the nylon will wear down . It might be possible to design a basic version for tank locos but would need to adapt it to fit gears, It would be up to modeller to decide how and where to fit motor. 1 Link to post Share on other sites More sharing options...

shipbadger Posted January 24, 2020 Share Posted January 24, 2020 Some years ago now but I had Bill Bedford produce a batch of his sprung bogie etches for me in 3.5mm scale. I had one on the stand at Warley a few years back. Tony 1 2 Link to post Share on other sites More sharing options...
HSB Posted January 24, 2020 Share Posted January 24, 2020 It would be nice if the old Firedrake bogie castings could be re-run. I've just had a look at a pair of unmade Commonwealth bogies I have and they were quite nice castings. 1 Link to post Share on other sites More sharing options...

The last time I found Firedrake online, their web site explained they had ceased trading so the proprietor could give full-time care to his wife. Looking today, they seem to have vanished altogether. If someone has a postal address, I would write to them and ask if I could buy the moulds / masters. They produced some appealing models, but finding this sort of thing secondhand is difficult, a bit of a lottery really. - Richard. Link to post Share on other sites More sharing options...

Not sure about specific Firedrake products, but you may be better asking on British HO website. They have an IO Groups site HERE which has a database of former products, and who now holds the masters, but I suspect you probably need to join the British HO Society to access the IO Group.

RMweb Premium 47137 Posted January 27, 2020 Author RMweb Premium Share Posted January 27, 2020 (edited) I've updated the table to add the Hornby 48DS, because I've just bought one, it is a beautiful thing and its chassis looks suitable for a freelance industrial project. Also the chassis kit for the 48DS by RT models, because it looks the part for a BR class 02 or indeed another project needing a 6ft wheelbase. I think it's quite funny how the discussion here has moved on to coaches quite so quickly. If we find a useful resource for coaches or indeed wagons, I can put the details into the table and change the title of the topic into something broader. - Richard.

rue_d_etropal Posted January 29, 2020 Share Posted January 29, 2020 Don't forget the original Bachmann GE44 loco, with 2 motor bogies. Well liked by narrow gauge modellers. Can still be found, its the one tat is not DCC ready or onboard. About same size as the Ruston. There are other small Bachmann motor bogies which coud be useful, eg the San Fransisco tram/trolley car. Then there is the OO Wickham trolley whichmust be useful. As for coaches and wagons, I have the coach bodies covered for 3D printing(all my designs include HO). For bogies I would recommend a basic internal chassis for bogies(easy to design for 3D printing) with a range of different wheelbases, and sides produced separately. 1 Link to post Share on other sites More sharing options...
rue_d_etropal Posted January 29, 2020 Share Posted January 29, 2020 I've given my thought to basic loco chassis. Assuming axles are normally 1/8in, what isthe recommended size for bearings. Romfords/Markits do ones in 3.something up to 4mm. I can make holes suitable for any, but would only want to do one size. I checked out motor/gearboxes and Ithink they can just be fitted inside frames so as long as that is minimum of 9.3mm then abasic chassis is easy to do. Far easier than trying to work out positions of motors and gears. Link to post Share on other sites More sharing options...

I will add the Bachmann GE44 chassis if it has a straight application for a prototype used in Britain other than a GE44, or if you can supply the basic dimensions, or both. But saying it is well-liked by narrow gauge modellers seems completely off-topic. We need focus if this table is going to be of value. I cannot even work out whether you are describing a 9 or 16.5mm gauge locomotive. The Bachmann Wickham trolley has the motor in the trailer, and tiny wheels. Surely, no locomotive would be built from such a tiny basis? - Richard. Link to post Share on other sites More sharing options...
Allegheny1600 Posted January 29, 2020 Share Posted January 29, 2020 I have finally (!) got around to digging my "Austerity" chassis out from storage, it was well buried. Wheels are 14.95mm diameter and wheelbase is 19.30mm+19.30mm, unfortunately I'm a bit too focussed on other things to concentrate on the build right now. I found Simons post here useful as I happen to have one of these, it was gift from a friend many years ago; There are other small Bachmann motor bogies which coud be useful, eg the San Fransisco tram/trolley car.
