It seems an age since making any real progress with my little Drummond 4-4-0T. Having previously cut the parts out for the cab I have now managed to get it, almost, to a stage of completion. Despite looking fairly simple there were a few tricky parts to complete, the first being the beading round the cab opening. Unlike most locomotives the end of the beading on the R class turned outwards so that the handrails were outside the cab. To simulate this feature the beading was cut short and small fillets soldered to the ends. Once in position a hole was drilled to accept the handrail and the end of the beading filed to the required shape.

Before soldering the front, back and sides together as much detail as possible was added whilst the parts were on the flat. Spectacles were turned from brass rod, the rear spectacles had the addition of bars to protect the glass from the coal being loaded in the bunker. Small strips of 5 amp fuse wire solderd across the rear spectacles to represent these bars.

I hate looking into the cab of a model locomotive and seeing a set of wheels. Real locomotives had splashers covering the wheels so these have been included in the model. To make the bending of the splashers easier 5 thou nickel silver was used to form the top of the splashers. The rear sandboxes and reversing lever have also been included, all that is left to do in the cab is make the backhead.

One last bit of progress to show before returning back offshore tomorrow.

The boiler has been made from brass tube. I initially tried to produce this from nickel silver sheet but my rolling bars wouldn't produce a small enough diameter tube. There's nothing wrong with using brass tube but you do need a bit of heat when soldering anything onto it. The smokebox has been built up from a layer of 24 thou thick brass sheet with a wrap of 10 thou nickel silver soldered around it and the saddle.

Lookin' great. :):) Knee deep in coaches at the moment. Might have something done by the time you come back.

I hope so, I'm looking forward to seeing them. :thumbs: Can't help thinking though, you're gonna need a few passenger locomotives to pull all these. ;)

Locomotive(s) will start after the AGM in a couple of weeks time. I' m trying to get some coach stuff together for the AGM between now and then to show that I'm actually doing something. :) I'm re-thinking drivers in any case after seeing the shape of the bosses for your 439 class. I re-checked my drawings and found that the fatter, pear shape seemed to be standard on a lot of the Caledonian locomotives - one of these things you don't notice till you actually start looking closely at drawings, etc.

I'm also looking at using the CNC machine to cut some spoke centres - for a 498 class - the dock tank with four foot wheels. That's what I got the machine for initially so I thought it about time I actually tried to do something like that. :)

Your right, I had never taken any notice of the bosses either. I changed the throw on the 439 wheels as I was concearned the original throw would be too large and end up fouling against splashers. It wasn't till I decided to alter the throw that I learned how much smaller on the 439 it was, and how much of a difference it made a visually.

The 498 class is a lovely lookin loco but I wouldn't have thought there was much call for one on Banavie Road.:confused:

The next - read first :) - loco will be a 1 class tank - the Caledonian's answer to your NB tank, only with condensing apparatus for the underground lines. In fact, it would be quite interesting to run a ruler over the NB Class R and the Caley Class 1 and see if there were any major differences since Drmmond's successors on the Caley seemed to stick with most of his design principles until Pickersgill came on the scene. :) I'm still trying to work out a good way to do the footplate on a 670 class, so I've opted for a passenger tank to pull the coaches. :)

The dock tank is for something else - :) - and I was only looking at its driving wheels to see how best to make them.

Jim,

When you do get get round to making a start on that class 1 I hope you'll keep us all posted on it's progress. :thumbs:
