Hi Graham,

Are we talking about the middle cylinder? if so there is nothing provided for this by DJH - it's very much a only provide what can easily be seen and nothing more......

Robin - the outside cylinders.

What movement, if any, does the DJH kit provide for the piston valve spindle?

Hi Graham,

This is one of the bits that I too am struggling with - The bit highlighted in red below is the only bit that comes with the DJH kit and this fastens to the frame space with a screw. The same parts are there for both sides. What I need to work out is how to solder a lap joint of nickel silver between two whitemetal wings without melting the whitemetal - The bit in the blue square is the lap joint rather than the pivot shown in the drawing

I hope this makes sense

Robin,

Ouch!

There is some sense in GWR 2 cylinder locos with Stephenson gear... less pain on the fingers.

Hi Graham, as with many things talking and thinking about my particular dilemma in order to describe it to you has possibly provided and answer - wet tissue to protect the castings and using the "bolt to the frame spacer" to hold it in position and a quick dab with the soldering iron may do the trick.

Yesterday the coal hole lackeys packed as much coal as could be packed into the limited space of a Tram body and the crew set off for Stratford.... for the engine is going to receive a lick of paint, about time too seeing as the model has been "finished in brass" for the last seven years or so (not quite a challenge to Diamond Jubilee).

The journey is likely to take some time for the tram is not able to run at "line speed" and so the poor thing may well get put "inside" more than once on the journey. A bigger concern is that the water capacity of a tram is very limited and there are no water columns between here and there - the odd bottle of Evian does not go far with these engines.

Oh, one last thing... the fitters had to do a rush job before departure. The side-skirts and cow-catchers of the tram had to be removed before the engine was allowed to leave the yard, something about the tram bobbing and bouncing and the possible risk of flash-over from the 3rd rail.

The tram may return by the time of the Basingstoke Club Open Day - passing times are not likely to be posted on "Steam Tours UK" on the grounds that most photographers will have gone home in disgust after waiting hours for a late running working.

The lick of paint for the tram (see post #36) includes BLUE....

So that makes two BLUE locos... amongst varying shades of green.

How wrong could I be?

The tram and the trusty crew departed North Hampshire after elevenses yesterday... by way of Oakley Goods Yard (closed by you-know-who) and arrived at Stratford Works (re-located using funding from the 2012 Regeneration Programme) just before noon today. The advisory telegram, delivered by a Weeping Angel, states simply:-

"Tram arrived 11.15 inst. <stop> 8 mph speed limit exceeded result of governor drive disabled <stop> LP fuming driver on carpet <stop>"

C'est la vie.

Although the dust has settled after the flaming row between the tram driver and Parks the progress on painting of the tram is not as intended... something about Stratford's painters having a holiday whilst awaiting replacements for the engine number plate - nicked by the metal pikies whilst the engine stopped over en-route from Oakley.

So rather than having to cut the grass, service the car or other similar interesting occupations I have been given the task of getting a Class 37 "running" for the Basingstoke Open Day - next Saturday. This job has taken on an added interest after helping Ian Pope with Knockley Gate III at the recent Farnborough show.... conversation wandered back to the 1960s and the traffic working in the Forest of Dean. CME of Scrufts Junction jovially remarked "Lydney Shed are going to send an English Electric Type 3 up to Whitecroft next week" with a bit of a smug grin. Reply from Ian soon removed the grin... "Yes, there was at least one working because the Class 37 was cleared to Parkend"... followed by "I might get one of Pete's new hydaulics because they went up the line as well". Damn, another expense due by the end of the year.

The fitting of ABC motor bogies is not as easy as I thought... the motor is sitting just where the cab back bulkhead is screwed to the floor. I think that I shall have to remove the floor fixing from the rear bulkhead and re-attach the fixing point to the front bulkhead. At the same time I shall have to provide a route for the marker / tail lights from the engine compartment to the nose without going through the cab, below the floor and through the cross-member surrounding the bogie centre pin.

Even blackening of the bogie wheels is not as simple as expected.... the electrical pick-up is via plungers which run on the back of the tyre so that masking of each wheel includes the tread, the back of the tyre and both sides of the brass bush (which entails going dotty).

I have to admit to not going there - I just mask the tyre and apply the fibreglass brush/back of a scalpel blade to the backs of the tyre.
