7mm The Derby Line - Rolling Stock

[dibateg]

Hello Peter -
The tool boxes were obtained directly from Malcolm Mitchell. I actually left the padlocks off, on the basis that in 1957, they would not have been used. The etchings are excellent. Also, as to the year of 1957, I suspect the loco will have still had it's exhaust steam injector. So I've taken off the live one and substituted pipework. Sharp eyed readers will spot the 3rd pipe coming from the manifold as the loco is readied for a track test. I must remember to screw the vac pump back in place!
I must thank everyone for their input on this thread.

Meanwhile I've pressed on with the MMP Class B tank. It goes together nicely, just the non-metal stuff to put on now.

Hi Tony,
So you couldn't be arsed making a few spanners! Only joking.

Despite the odd choice of wheels by your client, it's a fine build. I really like the all metal appoach of the old Mitchel kits as opposed to the cast resin/cast metal firebox and etchings. Takes more time and skill to get right but is more satisfying to my mind, and looks better in the raw. That said, it makes no difference once the paint is on.
Cheers,
Peter

The B tank looks great, I really enjoy building MMP wagons, I just wish I had more time to do it.

Aside from any prototypical inaccuracies, the appearance of the wheel castings has been altered by unsympathetic turning processes.View attachment 82207

I was interested in your photo (no fillet between tread and flange), All wheels were profiled using profile tool from AGH.

 

[Brian McKenzie]

Message number 1203 7mm - The Derby Line - JLTRT 7813 Freshford Manor explains how and why some of the fillet between tread and flange was removed.

I've been out of action for over a week with the flu, despite the flu jab. I'm still coughing well mind. I did find some energy to get on with the ABS Iron Ore Tipplers.


D602 is back from Paul Moore, she is long, and I cannot get a decent photo at the moment.


I'm now on to Shirenewton Hall, I thought I knew my way around these having built a DJH 4mm Holker Hall a few years back. Does anyone have any detail pics? I might have to mount an expedition to the SVR to find Hagley Hall. I wonder why there is a big cut out aft of the cylinders and what those squares off the overlay are for?

 

[Compton castle]

Send Laurie at JLTRT an email he has loads of detail shots of the construction that Paul Hannah built,
Here’s my 5904 Kelham Hall being built at the moment.

 

[dibateg]

Thanks Steve!

 

[Dog Star]

I'm now on to Shirenewton Hall...

I wonder why there is a big cut out aft of the cylinders...

Because there is on the prototype. This is an original Hall and so follows the style of the Churchward Saint class... and that means that the cylinder castings meet on the centreline of the frame and sit on top of bar extensions to the frame plates proper - there is a lapped joint close to the location of the C-iron support for the slidebars.

 

[dibateg]

Thanks
I'm baffled by one or two things on this loco, the smokebox saddle doesn't seem quite right, I think it should have a flange all the way round... The sanding rod should have a crank behind the drop link for the reverser, I have no detail on what that actually looks like, I can't find anything in the kit for it.

 

[Dog Star]

Thanks

You are correct... and possibly wrong. On the prototype the top flange does go all the way around the top and there are bolts in each of the four flanges... only Nick Dunhill might include the flange and bolts though for the front and rear faces of the Churchward saddle are "dummy", made from thin plate (12swg comes to mind) and acting as covers for the insulation material around the block.

 

[dibateg]

Thanks! More Google searching shows that plenty of Halls didn't have an all round flange on the saddle.
So... a test assembly with the wheels - this one has to get around 4 foot radius too...



The cab goes together nicely, although some trimming was required for the window frames.


Persistent Google searching eventually found images of detail that I required for the running plate, there is a little tidying up needed, but it's nearly there. Top feed pipes take a variety of routes through the running plate. On this particular loco they are towards the rear of the trailing splasher.

 

[dibateg]

So I've been cracking on with getting the boiler installed and adding the detail. It's almost ready to come off the cradle now..



The boiler is held in place with self tapping screws. Loctite 480 is used for the small details.


Next step is the cylinders and I suspect the glands should be set at an angle but with JLTRT closed for the moment these will have to do. That's a pity as JLTRT have moved O gauge along and I have had a least half a dozen JLTRT commissions. Laurie is always extremely helpful, I hope that it works out in a positive way.

 

[Nick Dunhill]

Er Tony you might like to have a look at this.....

I've spent half a day grinding and cutting the underside of this engine to get around 4' curves, so I think we are there. The front of the cylinders have to be carved unfortunately. I like the way some of the pipes are tidily hidden by the reversing shaft. The snow has kept me indoors for 3 days, so I've made good progress. Despite some minor issues, I do enjoy doing the JLTRT kits, I hope that they return in some form.



The ATC pick up would be mounted off the rear of the buffer beam, but I've had to cheat and put it on the bogie as it was clouting the bogie frame on curves.

 

[dibateg]

I'm on a push to get the Hall finished, but a couple of track tests have thrown up problems with the bogie. There has been a lot of grinding away material underneath! Fortunately, it's not that visible from above. I've also moved the bogie forward about a mill and a half since the photo was taken. The tender is from Randolph.


In the meantime I made up the backhead - an enjoyable mornings work. This loco has an exhaust steam injector, I now know to add the extra pipe down from the manifold:-

 

[dibateg]

4967 will be returning later in the year for final assembly after painting.

Next up is 10001, the other twin and I'm washing up again to remove any residue from the moulds. Fortunately Heather did a comprehensive documentation of her build a year or two back, which has some very useful information. This 10001 is modelled somewhat later towards the end of her active service.


One of the cabs is for 10000, and in the past, a call to Laurie would have a replacement quickly in the post. So I had to file, scrape and emery off the extra vents on the cab roof. I've left a little ledge at the end to avoid damaging the rain strip. That was carefully removed last.

 

[dibateg]

Although I checked carefully I still didn't spot the missing bogie outer end frames. I'm now on a hunt for them, I might have to fabricate them up:-


It's a bit of a JLTRT fest at the moment and yes, its a white out outside..:-


10001 didn't have the resistance banks in the cab, so they were cut off with a junior hacksaw, and some new panels made up from plasticard. It made a monumental mess. Hopefully I'll be able to tidy up the bulkhead a bit more...


The lamp irons in the kit were not quite right for the ones on the corners, so they were made up from brass strip and mounted on 0.6mm wire. The black marks are stains from Loctite 480, my superglue of choice. 10001 had extra handles on the doors at the end. I like these bit of engine picking.
