Jack P Posted January 17, 2020 Share Posted January 17, 2020 1 hour ago, Departmental said: Ok, dont worry about the pic, just a opinion as to the space available would be a help There's a large block that the wheels slot into, the space between the inner side frames of the crane is slightly over 22mm. Its about the same on the jib runner and match trucks. I hope that helps! 1 Link to post Share on other sites More sharing options...
Departmental Posted January 18, 2020 Share Posted January 18, 2020 Thanks for the pictures and measurements. The external wheel face to face of a P4 wagon wheel axle is 20.60mm, which will be a bit tight! I notice that the Bachmann axles are a lot larger in diameter than P4 wagon axles so some new machined axles will be called for. I think that the crane might not wish to run with such tight tolerances after modification, and or grinding out the inner faces of the main chassis molding. All in all, a very nice model, but not one I am prepared to have to 'butcher' having paid £200+ for! Again thanks for your help in providing some photos Link to post Share on other sites More sharing options...

RMweb Gold deepfat Posted January 24, 2020 RMweb Gold Share Posted January 24, 2020 Hi, I got the SR Grey crane for my birthday and I love it, however what would a typical era 3 train look like that this would be part of - what pulled and what other wagons and coaching stock would have accompanied as it went from job to job.

Tony Cane Posted January 25, 2020 Share Posted January 25, 2020 (edited) On page 34 of this topic, near the bottom, you will find some quoted information from Mike King. Failing some photographs of the train in use this is probably the best information available. There is a picture of one of the Southern cranes attending a derailment in 1940 in the publication Southern Way Special No 3 Wartime Southern. This is probably 1561S as the location is near Guildford. The support train is present in the background and consists of two arc roofed bogie coaches. The only other detail shown is that the nearest coach has a lighter coloured roof suggesting that it has recently been repainted. The attached pictures show my current progress on producing vehicles to go with 1561S. Any modelling of similar vehicles is going to require at least a repaint. I cannot think of any source of a suitable ready to run arc roofed non corridor brake coach. The LSWR rebuild by Hornby is a possible option and simple modifications such as removing the duckets, 2/3 of the door and grab handles and adding a stove chimney, would get you closer in appearance. Other than that you are into the brass kits or conversion of Triang clerestory coaches.

On receiving my crane I contacted Mike King with the same question and the following is from his reply [note that his references are to sections of his recent book "Southern Coaches Survey" which is essential reading!]: "...the prototypes for the Bachmann crane are 1560/61s, new in 1940. These went to Nine Elms and Feltham, with one moving on to Guildford not long after. No new conversions for riding vans were done at this time, so it appears whatever existing coaches/vans continued in use. Feltham and Guildford had ex-LBSCR 54 ft coaches at that time - either 5-compartment brake thirds or composites. The easiest to describe are those at Feltham - 1470s and 1471s (ex- 3934 and 3993), which were former Diagram 199 brake thirds and conform to the diagram, so they may be found in section 9 of "Survey". Apart from the usual removal of lookouts, the only external alteration was to fit stoves so there is a chimney in the roof of each coach - roughly in the middle of the former passenger compartments. Interiors were largely stripped out. In addition, Feltham also had SECR 6w brake 1619s, formerly Diagram 882 van 485 and details of this may be found in section 5. In this case, no external alterations (not even removal of lookouts) but a stove fitted near one end. Livery might be grey or red oxide, but all three look tatty in pictures. As you say, sourcing models may be a problem - the SECR van was done by Branchlines some years ago, but I do not know if this kit is still available..... Otherwise, Branchlines also did some LBSCR 48ft and 54 ft coach kits as well - but not sure if Diagram 199 was amongst them. Or, you could chop up the old Triang clerestories - my normal method of sourcing Brighton coaches." I doubt that there is a better source than Mike, so the issue is finding appropriate stock. I can't see that the Branchlines kit he refers to is still available, but perhaps another option might be butchery of the recent Hattons 6 wheelers? I intend building an SR breakdown train to run with the crane and will post my efforts in due course on my layout thread - but this may take some time! Tony For those asking i'll quote the answer Tony gave me, I found it extremely helpful - but have only just got around to ordering "Southern Coaches Survey". For anyone interested I thought i'd add some in progress shots of the weathering/detailing achieved on my crane so far: Edited January 28, 2020 by Jack P 24 1 2 Link to post Share on other sites More sharing options...

I bought it as a reminder of times past rather than to run on the layout. Mine is still in the box because I don't really see the point of getting it out until I'm a bit further on with the layout. Even there, it will be very much an interloper so I'll need a liberal application of Rule 1 to justify it. But I do think it will make for a good cameo scene - the argument, possibly, being that the yard I'm modelling was used for overnight stabling for the crane rather than taking it all the way back to the depot. I'm a little scared of weathering such an exquisite (and expensive!) model, but maybe I'll practice on the Oxford 15t crane when I get one. 2 Link to post Share on other sites More sharing options...

Pre Grouping fan Posted February 9, 2020 Share Posted February 9, 2020 Just spotted this over on facebook, someone has managed to get 2 electric motors in the boiler area to motorised their crane. Using a DCC decoder to operate the motors one at a time. He's also investigating motoring the slewing mechanism. https://m.facebook.com/story.php?story_fbid=678359559572736&id=397738487634846 Not sure if you will need an account to look at it depending on their privacy settings 3 Link to post Share on other sites More sharing options...

That is how I guessed it would be done, two parallel motors linking to the existing worm mechanism. The slewing mechanism might be a bit tight given the ballast weight/chassis block, but I'm sure doable. Will be interesting how he got electrical wires in there and what limit there will be to slewing with the electrical connections in there, assuming there are pickups fitted to the wheels Link to post Share on other sites More sharing options...
craneman Posted February 9, 2020 Share Posted February 9, 2020 The slewing motor could be fitted in the carriage, along with a travel motor if so desired. It would really need slip rings to connect to the crab in order to allow full 360 slewing. It is a neat start, however, and shows it can be done. I guess ideally there'd be a further motor driving the crane's engines separately so that the crankshaft can run with any or all of the crane's other motions (it could also run with none of the crane's other motions, as you do when warming the engines before use). The derricking gear needs to be slowed down a lot from the video though, that is much to fast to raise the jib. 2 Link to post Share on other sites More sharing options...
Popular Post RJdeVries Posted February 11, 2020 Popular Post Share Posted February 11, 2020 (edited) Hi Gents, I'm the one that posted my work on facebook regarding the motorization of the crane. I've had it in my possession for about a week when I got the idea that motorizing the crane would be more fun, and a challenge at that. I've bought a pair of motors with wormgear at a local show a few days ago thinking these could maybe do the job, these are designed for the faller car system, so moving around lorrys and busses. Motorizing Ransomes and Rapier by Robbert Jan., on Flickr I've made a lot of changes to the motor mounts in order for them to fit neatly inside the cabin surrounding the boiler. The gears that are on the imput shafts where removed and the wormgears pressed in their place. Motorizing Ransomes and Rapier by Robbert Jan., on Flickr A lot of fitting, checking, fitting and finally testing later I was very pleased to see that the motors could provide enough torque to operate the mechanism. As I progress I do understand that the crankshaft should spin free when disengaged from any of the motions, having taken a look that would involve realligning one of the gears so it would not get engaged at all, allowing for a separate motor to drive the crankshaft. The clip below shows the progress so far, It's to fast I know, it can however run as slow as some clips ive seen of the real thing in action. Regards, Robbert Jan the Netherlands.
