At least you figured out you had striped the wrong end before going any furtherI do wonder about myself at times
Its looking good and certainly belying its origins...

So did you paint the inside of the new planks, then, Simon?
Jolly nice job, of course, by the way.

Finally lettered the PO wagon last night, "Onebits" watersides, with Micro sol and Micro set, "Kleared" over this morning. On a roll, I dug out my CCT transfers for the Lowfit and did that as well, same process. The CCT lettering is a little translucent but looks fine nonetheless.
Both wagons snapped outside earlier this morning prior to some civil engineering works taking place.
Ought to get the Fordson loaded on to the Lowfit!

I thought I'd better get back to the serious stuff and so spent a couple of hours knocking up a switch mechanism for the second yard turnout this afternoon. I'm going for a more self contained and hopefully stronger enclosure. Here's the first iteration, it may be useable but in truth the crank sits a little bit too high and the throw of the arm that connects to the drive rod is too little - not quite reaching it. The over centre spring arrangement feels better than the first one however, in this design its easy to put spacers in over the bolt and thus compress the coil spring further for a more positive action. It needs a "lid" and lever and pivot, but that is straightforward once this mechanism is working. More pottering required...
And here's the first turnout, microswitch all wired up, lever painted and ready to be planted in the garden. Ballast material will cover all the plastikard webbing and bases, together with the wires. I will be making some sort of cover for the mechanism etc.
Once this second mechanism is sorted out I am in a position to lay the whole yard

As reported on the Launceston Road thread, D6319 was failed with engine problems on Monday last.
Running was not as smooth as it should have been and in one direction things didn't sound at all good. Upon removing the "slug shield" I found quit a lot of brass "grit" and looking at the gearbox could see that the gears on the secondary shaft appear to have moved out of place. I therefore removed the motor and gearbox in order to send it back to ABC, I guess, I can't see that my installation would have caused this failure?
Unfortunately getting the gearbox out was quite destructive, as the delrin sprocket was pinned through the axle and I had used superglue. I had to destroy the sprocket to get the pin out and then the roughness on the axle made drawing it back through the roller bearing nearly impossible, which in turn has de-attached the bogie frame side from its end, it's all a right mess
All repairable but it does make me wonder whether my D6319 isn't almost as jinxed as the real one was. (It was reserved for preservation but got cut up instead)
And in the meantime 30313 really needs a new motor and gearbox combination to make it work properly - looks like its a bus replacement service again

Simon,
Not your fault I think, there's something a little awry with that gearbox. My guess is that there's a spacer or similar that's dropped out (or worn away?). However you look at it that intermediate gear has had it. You might see this as an opportunity; you can see if Brian can fit ball races when he rebuilds it which will extend the life.
Mick,
Unfortunately the ABC gearboxes don't work like that; the intermediate shaft turns on a fixed axle, so fiddling almost certainly involves taking the shaft out. The gear is knackered anyway, so back to ABC it'll have to go...

I have emailed Brian including the above picture and I'm sure he'll be able to assist one way or another. I want to buy another two gearbox/motor combinations from him anyway, for the T9 and project Watersmeet.
I can't remember whether there was a spacer, it is all a bit perplexing....
Going back to D6319, I may take this opportunity to spring the driven axle with the same horn block arrangement I concocted for the undriven axle, if nothing else this would make taking the motor and gearbox in and out much easier. I suppose I ought to correct my slight ride height issue and ball race and spring the other bogie while I'm at it, all quite a lot of work

Steph,
Yes see that now, as you say looks like a thrust washer or something has come adrift and let the intermediate gear move over.
Not sure it's had it though, surely it's only the edge that's damaged and if it's moved back to the right location the worm will run on the un-damaged part?

Looking at it closely, the brass filings have been caused by the intermediate skewed gearwheel running up into the brass boss through which the driven axle goes, this is milled out to clear the skewed gearwheel when it's running in its "normal" position. I'm guessing everything is therefore re-usable except the skew gear.

Looking at the gearbox the gears should be OK, the hard part would be getting the two sides and bearing holes in alignment. In this case it looks like a shim washer has been missed from the L/H side (about 1/16" -3/32"), Looking at the shape of some of the gearbox frames it looks foubared to me. Unless you can get the main bearing in alignment.

I had a very helpful email from Karen at ABC and the whole assembly has gone back to Brian for attention.
I also took the opportunity to order new motor/gearbox combos, one to drop into the T9 and the other for project Watersmeet, whose time must surely be approaching.
Passengers are in the meantime enjoying the buses, a foretaste of things to come we fear

Today I cleaned up the bogie frame and soldered the torn apart corner back together.
This is a bit of a bodge, but I think I can correct the ride height issue (the powered bogie rode a bit high) by filing the holes for the roller bearings oval so that the bearings sit higher up into the frame. I have now done this and fancy it will work, although I think I will need to secure the bearings to the frame, not least as one of them wanders across the axle. It's not pretty though…
I have re-soldered a pipe to the locomotive end that fell off last year and am re-fixing the two missing guard irons. I am also going to make better pick ups for the trailing bogie using Brian's phosphor bronze although I'm not fitting roller bearings, mostly because I can't find the four I bought for the purpose To be fair, it runs pretty freely as it is.
I must remember to make a new windscreen wiper too.
Hopefully the motor and fixed gearbox will be returning soon.
Got to get this back together asap so that I can pursue new projects…..

As Dennis has offered to paint this into S&D Prussian Blue with full lining, I have been working on a boiler back head to finish off the improved interior.
This model was originally built around a carved up "Big Hauler" back in the distant past, I have more recently nearly made a new chassis for it and it has a set of Mark Wood wheels waiting to be used too.
The back head is largely built up from scrap but with four of Laurie Griffin's very nice handwheels adding a bit of class. A bit more work left, firebox door catches, brake valve and suggestions of gauges mostly.
Trying to understand the Midland's two part firebox door arrangement has caused a bit of head scratching, I'm not sure it's quite right but it will have to do - don't want to out-do the body
