Hi Mike

 

are these an etch which could become available to buy? I have the three silver fox sr protoypes to build one day and these would be perfect for them.

 

Kind regards-richard

They aren't etched, I didn't have time in this case. The frames (and compensating beams which weren't very visible in the photos) are cut out in the old fashioned way with paper patterns and piercing saw. There are compensating beams inside the frames linking the two outer axles (inner ones are fixed), these are jig drilled from the frames. This isn't full compensation but it;s a lot better than all rigid.

I do have some etches for HE 1685 - and yes I did look up the name - but don't hold your breath.

 

This caught my attention - good stuff! Fingers cross for HE 1446 /1929

More work on the Hunslet 0-4-0T this week.

The sanding gear is rather complicated, quite why the leading sandboxes had to be up on the smokebox I don't know. The sanding rod comes from the cab to the LH box but has another crank on it fitted in a tower to carry a cross rod over the boiler to the RH one - most photos of HE 3665 working at Cadburys show much of this gear had disappeared but I've put it all on anyway. The sandboxes were made up from some etched components and worked out very well.

By thius time I was really wishing that I had fitted the weighshaft before I built the tanks but it was a long time ago. The weighshaft itself has to cut across the boiler clothing, no photos of this and Don Townsley didn't show it in his drawing so I've had to guess that it was cranked like this. It could have been recessed into the boiler clothing but this is easier - it could still turn far enough to get from full reverse to full forward gear.

One thing I concentrate on when building anything is, regardless of what the drawings and everyone else says, does it look right? One trick I use on myself is to park nearly completed locos on the test track at the end of the working day. Next morning I walk in, sit down at the computer and look up, at this point I see it through new eyes.

This was the view this morning with early sunshine through the window - it looks just right!

The style of the printing gives away the identity of the draughtsman! Are there kinks in the long horizontal lines?

[Michael Edge]

Yes, it's an old one from Railway Modeller November 1965 - a Leeds MRS special issue, most of it written by club members (bit before our time though!).

Cylinder drains are rather prominent on this loco so I've put rather more detail than usual in, photo also shows the typical Hunslet brake rigging.

Finally finished this afternoon, it's taken at least 25 years. Modern techniques caught up for the motion work which was etched in .022" n/s.

View from the back, a slight snag emerged right at the end of this - one of the last jobs was fitting the return cranks to the driving crankpins. It quickly became apparent that the Slater's wheels (I've no idea which they are after all this time) didn't have the correct crankthrow and the return cranks are too long. If I set them in the right position they give far too much movement to the expansion link so I've set them for now in the minimum position (still too much but not so bad), I think I'll have to make new ones.

Clearance behind the crosshead was just about zero and at this crankthrow the little end coincides with the leading crankpin, the fastener was already absolutely minimal so I finished up not putting the back on the crosshead - seems to work quite reliably though. Another complication with this is the weighshaft above the footplate so the lifting links are not attached to the radius rods.

I don't really know what to do with this loco now, I've no need of industrial 7mm locos and don't even know how to paint it. I don't really want to paint it as Cadbury No9 (or more likely get someone else to do it) and Hunslet didn't actually build any others exactly like this one.

That's three long standing jobs completed in the last couple of weeks or so, now what can I dig out of the pile next?

Presumably the livery for Cadbury No 9 should be chocolate brown? Don't worry, it is only an attempt at late night humour!

Hang on to it for another three years and give it to DHT for a 90th birthday present.

No joke Tony - it was! More milk than plain though from photos I've seen.

I had no idea! It wasn't  one I am familiar with. That just has to be done Mike, it will look great on the exhibition stand even if you have no plans to run it anywhere.

Won't it be tricky to spread the melted Dairy Milk evenly over the loco though?

That is one loco I want a model of, complete with RMB 1808 (no running number) and an unnumbered TSO.

My favourite industrial. First rode behind at Dowty RPS.

Heh.  Well, Cadburys' locos are the other industrials on my list to partner my Longbridge Hunslet 15"s!

 

I think I'll have to wait before I order these though...

Different loco but nice to see the livery.

[Steamport Southport]

Isn't that one of the Avonsides which were very similar to the GWR 1101 Class?

 

Some information on the Cadbury locomotives here. Seems some were chocolate whilst others maroon (colour of the Bournville wrapper I assume).

Yes it is, the Cadbury ones predate the 1101 Class by about 20 years.

[MJI]

Are there are models available?

[Michael Edge]

Last two photos of HE 3665 before it goes to be painted.

 

Whistle string added and the return cranks shortened to match the crankthrow of the Slater's wheels, I'm a lot happier with that now.

 

Now for something different, another C14 but from a different railway.

 

This is the LSW C14 0-4-0T, converted from 2-2-0T railmotor locos. I have two of these to build for customers and so etched most of it, Nick Toix has already built the 7mm version of this etch.

Frames and coupling rods in the Poppy jig, my usual compensation system, drive will be on the fixed trailing axle.

Completed frame with Gibson wheels and footplate assembled, baseplates for smokebox, cab, tanks and bunker bolted on. I don't usually fit Gibson wheels at this stage, they will have to come off again, but I didn't have anything else small enough to set the loco up on.

The first three basic components, middle of the cab floor will be fitted to the frames.

[Enterprisingwestern]

 

To save the Gibson's would it have been possible to use 12mm wagon wheels on shouldered axles for setting up purposes?

 

Mike.
