34theletterbetweenB&D Posted December 7, 2023 Share Posted December 7, 2023 'Screaming' is usually symptomatic of the motor shaft slipping in the drive gear, and accounts for the reluctance to move. 2 Link to comment Share on other sites More sharing options...

And, there are still lots of things here which you've bought as well.............. Regards, Tony. Many thanks, Tony. Pressure of work has precluded a visit this year, despite the best of intentions, but hopefully that will ease in the coming months. 2 Link to comment Share on other sites More sharing options...

It arrived very well packed and in really good visual condition. However, on the test track it refused to move and gave off an unpleasant screaming sound. With a lot of prodding it moved, was controllable and smooth, but still very screamy. When I tried to switch direction it stopped dead and only moved when given a smart tap in the right direction. It doesn't move at all on my rolling road, just sits there complaining, so I can't try to run it in. Does anyone have any suggestion that doesn't involve sending it back and getting a refund? It looks great but I'm not looking for an ornament. Tony Good afternoon Tony, May I suggest taking the body off and applying current directly to the motor? At the same time as this, make sure that the gearbox is well-oiled. Failing that, if it still doesn't work, if you wish, please send it here and I'll look at it for you; possibly even fix it! Regards, Tony. 2 3 Link to comment Share on other sites More sharing options...

Tony It could be one of the intermediate shafts has slipped, they can come partly out of the frame plates and the result is a loud screaming noise and not much movement - they can also slide back in and all will be well for a while. 5 Link to comment Share on other sites More sharing options...

RMweb Premium thegreenhowards Posted December 8, 2023 RMweb Premium Share Posted December 8, 2023 On the motor gearbox subject, in O gauge we have fantastic helical gearboxes units available from either ABC or MSC (ex Ron Chaplin). Having tried one, I now never use anything else and I’m gradually retrofitting my fleet. They have the Portescap feature of being able to turn the wheels, but the main advantages are the power and quietness. I’m told the helical gearbox is much more efficient and it certainly shows in much lower current draw. I can easily get away with 00 decoders on locos so fitted which saves a bit. They're not cheap at just over £100, but compared with £50-£75 for a more conventional unit I think they’re good value. I’m surprised nothing similar has been tried in 00.

RMweb Gold john new Posted December 8, 2023 RMweb Gold Share Posted December 8, 2023 Taken the plunge on booking a Missenden loco course. Any Christmas money to go on some better tools.

Popular Post Tony Wright Posted December 8, 2023 Author Popular Post Share Posted December 8, 2023 One of the delights of inviting friends to Little Bytham is often what they bring with them. Three friends popped round yesterday afternoon; one brought a jammed-up tender-drive Hornby 9F (how I loath such things!), leaving it with me to see if I can fix it (a real 'delight'). Another brought this............. An ancient K's Kirtley outside-frame 0-6-0 (though not with K's mechanics). 'It just gave up' was the plaintive statement. 'Would you mind seeing if you can fix it, please?'. My friend is suffering from failing eyesight, so I investigated the loco this morning. The chassis had been built by another friend (very well), but the loco had indeed 'given up'! Actually, on closer examination, the 'fix' was easy. One of the brushes on the tiny Mashima motor had unscrewed itself somewhat, resulting in arcing at the commutator, then no contact. A quick adjustment, a clean and an oil and away she went. Now, on to that Hornby 9F............... 26 Link to comment Share on other sites More sharing options...

Tony Wright Posted December 8, 2023 Author Share Posted December 8, 2023 More 'success' today! The jammed-up tender-drive 9F which was left in my care has now been fixed. Well, not the jammed-up chassis (foreground). Take a look at the quartering of the leading driver in relationship with the others. It's at least a spoke out! No wonder it wouldn't roll, and I can't fix it. No matter, a friend donated another Hornby non-powered 9F chassis (background), which does roll. Naturally, seeing that jammed-up chassis is off a later Hornby tender-drive 9F (the body seen) it didn't fit the newer body without alteration and rewiring (and much dark muttering!). Anyway, my friend (who left the model yesterday) will now have a running 9F, though I wouldn't normally touch this sort of tender-drive nonsense. Why touch it now? £20.00 donated to CRUK. Thanks David and thanks to George for donating the 9F chassis. Perhaps the cylinders/valve gear off the dud chassis might be of use to someone. If so, please let me know. 8 1 Link to comment Share on other sites More sharing options...
RMweb Premium PMP Posted December 8, 2023 RMweb Premium Share Posted December 8, 2023 It very much looks like the jammed chassis has Mazak rot. If so that might be the cause of the jam if the chassis is deforming and breaking up. 7 3 1 Link to comment Share on other sites More sharing options...

Tony Wright Posted December 8, 2023 Author Share Posted December 8, 2023 On to more 'creative' things rather than mucking about with render-drive stuff............... Alan Rose has sent me the latest 3D-printed carriage created by his son-in-law. It's a 1911/'12-built GC 'matchboard' dining car. Other than fitting wheels (not supplied) and altering the bogies' pivot arrangement, this is how it comes; really, a 'kit' made up of five individual pieces! I've just got to add some wire trussing, couplings and the buffers (not supplied). Now, a request please. I've got some Jenkinson/Campling drawings which show the standard GC 'matchboard' corridor stock, but nothing on this catering car. Can anyone help, please with any sources of reference? How long did they last? Into BR days? Thanks in anticipation. 12 1 Link to comment Share on other sites More sharing options...

Someone else may be able to cross-check (e.g. with the Clive Carter BackTrack articles on LNER restaurant and kitchen cars), but looking at Longworth it looks like a GC 60ft RC to GC diagram 5M3. E577 is recorded as making it to 12/49. Less long-lived than the 5M1 and 5M2(5G4) kitchen cars that would be suitable for Little Bytham.

Looking at that relevant mighty tome, I see that GCR 5M3 is listed as a Barnum, and this carriage doesn't have the end-profile of any Barnum I've previously built (they're almost flat-sided). Though the window arrangement is identical, this carriage has a tumblehome. In fact, I can't find it in the book other than listed as a Barnum. Unless some Barnums had a tumblehome. Either that, or Longworth has listed it incorrectly as one. Amazingly (in less than an hour!), it's now complete and ready for painting (probably in plain brown). I substituted complete brass buffers (drilling the resin shanks caused them to shatter), and attached my own couplings. Regards, Tony.

Unfortunately Longworth has got a bit mixed up with his coach naming at points and so most (all?) the matchboard stock is titled Barnum. This couldn't be a Barnum coach as there were no catering Barnums, only the TOs and BTOs. Simon 1 1 1 Link to comment Share on other sites More sharing options...

Yes, too many matchboard carriages are listed as Barnums in the Longworth heavyweight volume. Regards, Tony. Link to comment Share on other sites More sharing options...
