TFW’s workshop

[Tim Watson]

Just been using the Mangle, built by the late Peter Clark to finish off two loops at the South end of CF.

We have been re-working the layout control systems, which will hopefully be operable, for our next Keen House Open Day on December 10th. The two turnouts were made by Mark Fielder and will have final installation on Sunday.

Third Copenhagen tunnel & lines under construction. Can you spot the contractor’s loco?

Lamp irons are little beasts that are always vulnerable and need to be well attached. I normally drill a 0.5 mm hole to locate the irons.

They are made from 0.5 mm wide nickel silver strip.

The strip is bent back on itself leaving a small piece visible, which will be the future lamp support base.

The long arm of the strip is then bent at ninety degrees to make the upright lamp support.

This is then tinned and soldered where the material is double thickness and then the long arm cut to length for the upright.

A few strokes with a file and the lamp iron can be put in the hole and with a bit of flux and a fairly dry iron sweated into place.

Final trimming (the lamp base is a touch too long) and fettling can be done when all four are in place, to ensure consistency.

Found some castings for the tender axle boxes at the show which with a bit of work, at work, will save me quite a bit of time.

Just finished detailing the tender front for LP. It is very unlikely to be visible, especially with the tarpaulin over the top. Still, God and I will know it’s there.

A successful evening making two massive components for LP: the atomiser valve for the cylinder oil feed and a couple of wick feed oilers.

The atomiser was made from some fine brass tube for the unions either end of the body, which was represented by a piece of nickel silver strip wrapped around it and also acted as a peg into the boiler cladding. The globe valve handle was represented by some phosphor bronze wire, which passed through the tube to also make the pipe feed. The twist drill is 0.3mm; used to make the locating hole in the cladding.

The wick feed oilers are quite conspicuous. The sand box covers may be represented by some transfer film at the painting stage: difficult to represent them to scale, otherwise.

The oil reservoirs were represented by a bit of brass bar filed in the middle to visually separate the two oilers.

Realised after looking long and hard that I hadn’t put in the rear two brake hangers. These make a big difference to the appearance and, frankly, take away from the need for the brake shoes themselves, which are tucked up well behind the frames. Ironically, the brakes themselves, being attached to the body, are not part of the internal chassis and so the advantages of split frame pick up don’t work here.

Exhibition maintenance on our locos on CF is a constant battle against fluff, not always helped by brake shoes. The engines can attract enough of the stuff over a weekend to set a Hotpoint tumble drier on fire.

At last the brake gear is complete and rigged (representative, rather than accurate).

The close up shows it filling in the bottom half of the chassis

It scarcely shows in the general view, as it is currently too black.

Lord President is almost complete on the LHS. There is a gubbins on the front of the Cartazzi frame extensions that ought to be modelled, but I don’t have a decent image or drawing of it. And of course the whistle and safety valves: a nice little turning job in non-tarnishing alloy.

Would be nice to get some good photos of LP before painting.

After filling a couple of silver solder porosities in the Wooten firebox and a very light rub down, the P2 has had a second coat of primer. The photo picks up two witness marks filed in to the top of the boiler cladding to show where the boiler bands will go. On a conventional round boiler, I turn very minimal grooves to achieve the same result.

This will again be rubbed down with very fine abrasive paper before the apple green is sprayed.
My tin of green had become very gloopy.

It was therefore strained through a nylon stocking into a glass jar.

Looking at the sediment that had accrued, there was no way that was going to go through a deVilbiss air brush and give a decent finish. Time will tell if it’s been successful. I often strain paint in the big scale stuff that I do: it’s surprising what comes out sometimes.

After fiddling around I still wasn’t quite happy with the finish on MM, so she’s been repainted over the last ten days.

Bit sharper now. Will be improved by weathering.

I have recently rebuilt / made a very tall and elegant bracket distant signal for Copenhagen Fields. It was originally made by John Greenwood 30 years ago, but this is its second re-building because of exhibitor knocks - probably not too much of the original remaining now. The spectacles need to be filled in and the sign needs to read “All engines must stop here if the signal is at danger”.

The next individual to damage it on the layout will meet a slow and painful demise....

Can you tell what it is yet?

Well it’s fairly obviously two sets of 2mm Scale Association etched rods. The one in the foreground is sold for the modern Farish Jinty conversion, whilst the rather more robust version is also sold for Farish conversions. I think that the one in the foreground is too delicate, being only 10 thou thick across the rods, as it is half etched both sides. Anyway, the thicker ones were used for the Farish Jinty conversion below:

After one days work, it now needs some couplings and weathering; the chimney has been replaced with a correct shaped casting. Quite ironic that the previous Grafar Jinty had a good chimney and poorly shaped dome. It runs really rather well, although I had to make new plain muffs, as the supplied ones were a touch too loose for my taste. All the running gear was chemically blackened before assembly. All in all, a really good introduction to making finescale locos - who would have thought that thirty years ago we would have such high quality commercial models available?

My students have sourced these loupes:
https://emea01.safelinks.protection...6yV/1VjZWSttS0u5fNsnZ6AYTNMKpipQs=&reserved=0

They are incredibly good value,
with reasonable optics. They cannot be fitted with prescription lenses, however. Obviously, not quite in the league of the ones I use, but the box is pretty good anyway!

Telegraph poles are often a bit of a Cinderella subject on model railways. On top of Gasworks Tunnel there was the mother and father of a telegraph pole that probably terminated some of the wires before sending them down through the tunnels. In fact the base of it still in-situ.

I played around with this and other images to try and work out what the pole consisted of. We are very fortunate that Bob Jones made some rather good telegraph cross arms to our design many years ago and these can be adapted quite well to a number of configurations. The pole was made from brass rod turned to a long taper, suitable length cross arms were added, soldered on at 90 degrees to each other, as well as bits of brass for the wiring conduits and other bits. The pole is firmly located in the ground of the tunnel top (it may remain a removable item), whilst the railed fence leading up to it was made from square brass section and rod, again well fixed into the ground. There was very little painting, as the pieces were chemically blacked and then dry brush weathered.

Cecily thinks that a mascara brush would have been just as good. Maybe she has a point.

There were a number of memorial engines specifically so named after the Great War. One of these was Valour, made by the Great Central Railway. It’s name plate commemorated the employees lost during the conflict.

These engines have always been one of my favourites and very appropriate for Copenhagen Fields.

So this will be my next 2mm scale engine. Made a start on the tender frames this evening, so that at least I will remember when the model was started.
