Guest Isambarduk Posted December 19, 2014 Share Posted December 19, 2014 I meant to say that one of the reasons that some motors 'go like this' is that they are taking up the end-thrust from a worm and worm wheel but they do not have bearings that are designed to cope with it. So, some people with light trains with locos with small wheels that do not run for very long and not so often will have no problem whereas those with heavy trains with locos with large wheels that run round and round for long periods and quite often will soon see this problem develop. Cannon's answer may well be something along the lines of 'These motors from our FGHIJK range are not suitable for applications, such as yours, that create significant end thrust; you should be choosing motors from our ABCDE range'. I shall be interested to see what transpires. David Link to post Share on other sites More sharing options...
Simond Posted December 19, 2014 Share Posted December 19, 2014 Last pic in Ozzy's post 2094 - there's certainly damage to the actual windings, partially hidden by the shaft. You could perhaps paint some epoxy over the wires, at the same time as fitting the shims that clearly should have been in there from day 1, as this may prevent them breaking, but I think I'm with Jon, it's probably already too late. As an aside, if the windings are "de-insulated", could there be a short circuit? My guess is "possibly". And could this completely nadger a decoder? Same guess...

ozzyo Posted December 20, 2014 Author Share Posted December 20, 2014 Hello all, this motor was replaced in 2012 with a new motor, and up to now no problems. This is the same motor and it did in fact ware through one (at least) of the windings. I don't think that it's a problem with the motor as such as one of my clients has a number of Castles and Kings that haul 12 coach on his large layout with no problems. I think that this is just a QC problem with the odd one. When I was test running it yesterday I did notice that my controller made a sound like an intermittent short but not enough to trigger the short cut out. So I'm starting to think that one of the brushes could be catching on the com. windings (or the soldered joint) in one direction. If this was happening to a coil that should not have any power in it could this cause the slow running? As you can see in this photo there is not a lot of clearance (this is not the problem motor this is the 2012 one). I have spoken to David? at MSC and I'm sending it back to him after Xmas for him to have a look at. OzzyO. Link to post Share on other sites More sharing options...

Kev_Lewis Posted May 18, 2015 Share Posted May 18, 2015 It would appear to be a later modification. She didn't have it in August 1953. https://www.flickr.com/photos/64518788@N05/7446145588/ Link to post Share on other sites More sharing options...
steve fay Posted May 18, 2015 Share Posted May 18, 2015 She's got a modified hall boiler in the later picture with higher degree super heater. So it would depend on the time frame. Note she has the newer improved draughting chimney in the first picture as well. If it was me I'd go for the latter option Link to post Share on other sites More sharing options...
ozzyo Posted May 18, 2015 Author Share Posted May 18, 2015 Hello all,well I've made a start on 6869, but first I'll let you see 'my' etches! First the two sheets of N/S a lot of these won't be used for two reasons, some of them are for the three 4mm gauges and some of them will be replaced by the S.D.K. The first two sheets of the brass etches, most of these are for the upper works. The third sheet of brass etches, boiler cab and a few other bits. Getting ready to tack solder the two frames together, part one.and part two. The frames after tack soldering together. After a bit of cleaning up and drilling a few holes and marking out a few more. OK who has nicked my springs? In the above photo you can see some scribed lines that are on a radius from the axles centres these are to check for the plunger pick-ups (4mm Gibson ones) so only a 2.5mm hole. You can also make out a vertical line to the right of the brake hander pivots this is for the safety chain hangers. To do the above I cleaned up one set of wheels, before on the left. OzzyO.PS. what else can I cut from the frames???? Link to post Share on other sites More sharing options...
RMweb Gold The Stationmaster Posted May 19, 2015 RMweb Gold Share Posted May 19, 2015 Hello all, this will be the next loco on the work bench, starting some time this week. 6869 1964 c.jpg I'm not sure about the smokebox header though ? OzzyO. The 'box' is an oil pipe cover - it covers the oil pipes where they come out from under the boiler cladding and enter the smokebox on their way to lubricate various components in the valve chests and cylinders etc. The engine went to Southall (81C) on 6 October 1962 - possibly on paper only at that time(?) and had a heavy general at Swindon on 18 October (not sure if that is the date ex works - I think it probably is) when it received boilerC6204, it had carried boiler C2847 fromNovember 1959 (all info from 'The Book of The Granges'). The only other pic I can find between October 1962 and withdrawal in December 1963 corrected to July 1965 shows a cover on the other side of the smokebox which suggests it might not be the boiler shown in your pic above; regrettably I have no information to link any boiler details to its number. Edit to correct date of withdrawl Link to post Share on other sites More sharing options...
ozzyo Posted May 19, 2015 Author Share Posted May 19, 2015 Thanks Mike, both of these photo have a date of 1964 so this should be boiler C6204. One thing that I have noticed about the boiler is that it has a cover plate at the bottom centre in about the place that Halls (and Mod Halls?) had a boiler support. The other thing is that it should be withdrawn by this date 1964. When you look at the smokebox door hinges they look to be white a Newport trait. This is starting to get a bit interesting. OzzyO.

Copy of 6869 1964 c.jpg Copy of 6869 1964 b.jpg This is starting to get a bit interesting. OzzyO. Always interesting with GWR boilers as they could have been on various classes although that patch is too far back for any of the motion brackets so would have been there for some other purpose - possibly even a repair? Alas I got the withdrawal date mixed up with a mileage date and the engine survived until July 1965 with no further boiler change noted. The last shed is noted as East Dock from July 1964 but lack of a shedplate doesn't help much with the latter picture as it was also phot'd at Banbury that year (without a shedplate) although the location in your lower picture could well be East Dock as various features fit that location.

K14 Posted May 19, 2015 Share Posted May 19, 2015 ... that patch is too far back for any of the motion brackets so would have been there for some other purpose - possibly even a repair? Early 28xx's have a secondary support bracket/plate at exactly that point - both 2807 & 2818 sport one, but 2857 doesn't. Link to post Share on other sites More sharing options...

ozzyo Posted May 24, 2015 Author Share Posted May 24, 2015 Hello all, after looking through my Hall photo I came across this one showing the second boiler mount in about the same position as the cover plate on 6869, so boiler No. C6204 could be a Hall boiler? Most of the last days has been spent working on the horn-guides and blocks, you now get cast horn-blocks with them but I'm going to use the turned ones on the right. The blocks blackened and nuts for the adjusting screws soldered in place. The three main parts for one horn laid out. All six of them assembled, it looks like I may have to do a bit more work to the two on the right. The first of the horn gaps cut out before the two frames were split. The two frames split and two more bearings fitted, I've still to drill the holes for the safety chains. After this I'll start work on the spacers. OzzyO.
