Thank you both! Have embedded the video and added larger gaps between text and photos - odd that it wants two spaces to make a 'one space' gap, as I was already adding the one space.

Rik - along with Peter Jones' book, your blog has been the other main inspiration for how to go about the scenic work.

Another productive day on t'pit!

That's the majority of the mechanical bits done - boiler next now. Conveniently Meccano nuts are square which looks the part on Georgian engineering, if a little over scale.

I've got one of those engraving tools that I'm going to have a go with for putting the stonework on the firebox tomorrow - not looking forward to that. Need to suss out a way of putting a taper on the four sides of the chimney (and find a longer bit of wood!)

What would you use for pipework? I'm thinking of trying it find some heavy gauge copper wire to bend to shape...?

Really enjoying this...

Instead of cladding the boiler with wood, which will be difficult, given the domed roof, what about cladding it with brickwork instead, constructing a brick dome over the boiler? That laser cutter really is a marvellous tool - I particularly like the moulding you've produced for the water tanks. :D

The boiler is where I've departed from the prototype in the picture, and gone for an uncovered domed boiler. The top is uncovered as per similar Georgian steam engines (take a look at the replica Newcomen engine at the Black Country Museum).

I had a bit of good fortune today - I started engraving the laser cut MDF boiler housing and realised that the burnt edges provided a lovely representation of blue bricks, when contrasted with the engraved away MDF showing through as light brown mortar. The top surfaces (which are un-burnt MDF) have been painted matt black and rubbed back before drying to try and give a similar effect. A bit of a conundrum now is how to achieve this finish on the chimney - the rubbed back matt black looks okay in small areas next to the nice burnt colour but I'm not sure it'll look the part all the way up the chimney. I guess I could just mix up a very dark brown and try to replicate the finish...?

The pattern I have engraved is over scale for bricks, as I was originally going to paint it as stone, but I like the look. In Bristol, there is the 'Black Castle', folly built in the 18th Century using blocks made from slag from the smelting of brass and copper so perhaps I'll say it's built from that!

I think the detail on the boiler top and the firehole door area here really shows how handy the laser cutter is - all built up out of 2d shapes...

That's about it for now until I come to install it on the line and do t[video][/video]he 'groundwork' - have to say, I'm well chuffed with how this has come out...

I achieved a passable match to the burnt edges of the MDF of the firebox casing on the chimney using quick drying matt black (blackboard) paint. I dry brushed it on, then rubbed it back with a tissue/my fingers to make it less dark. When dry, the bricks were then engraved, and finally it was all shellacked to a) stain the engraved bits, and b) after rubbing back with my fingers to give it a satin-y finish. I did two sides and got bored - need to finish the other bits tomorrow...

The motor is a 1.5-3v one, running via a 12v Hornby controller. The finesse of control just isn't there are I'm running so near the bottom of the power range. I think I shall have to hunt around for either a 6/12v version of the motor, or one with greater gear reduction - anyone have one knocking about that may replace this one? This is 30:1.

Onto the next project now!

Wonderful work all round, especially the woodwork! Great detailing with the pipes etc. You might find a Lego motor would be a better option, easy to gear down to a suitable speed and much quieter.

Thank you Peter! I like working with real wood, it saves a lot of hassle painting - I don't like hanging around waiting for paint and glue to dry, I soon get fed up and bored of the project then! To that end, I've always got plenty of quick drying matt black paint, quick drying oak stain, superglue, and shellac about - you can get by with most things with that!

I've had a look on MFA's website and they produce motors of the same footprint and mounting arrangement as this, but with different gear ratios and suitable for different voltages, so (although there are other benefits that you mention) I'm loathed to go away from this type - as you can see, it's all pretty tight in there, and a drop in replacement would be ideal! Re. noise and so forth, it probably won't actually get used all that often, more of a "yes, the coal mine does work" when visitors are around!

Next! The coal mine needs a ventilation system, so I've gone for a great big fan, and as it's a Georgian mine, it's going to be powered by a Trevithick dredger engine as in the Science Museum. Motor to be hidden either under the engine or in the fan - the design is still rather fluid at the moment!

The next logical step is to put a similar model on wheels and have a 16mm scale model of Catch Me Who Can?... (or indeed any sort of Georgian locomotive).

Currently the bearing surfaces are wood on steel (except the crankshaft) - not sure how well this is going to last, perhaps okay considering it won't get used very often. Certainly, if I was building a locomotive like this I'd enlarge the conrods a tad and add brass bushings.

A bit more painting needed, quarter the crankshaft correctly and to sort out the drive system, but that's the Trevithick engine done for the coal mine. I've backed myself into a bit of a corner with motor/gearbox/drive options...

I think I'm going to use one of these: https://www.ebay.co.uk/itm/Miniature-12 ... Swvg9Xe8ac

But I can only fit gears of 1/2" dia or smaller in the space available, so still trying to track something suitable down. Rik, if you're reading this, where did you source the bevel gears for your railcar build please?

The easier solution would be to hide the motor in the fan and have that drive the engine, but think I'm going to build a version on wheels too so it's worth proving motor mounting out out with this. Should be able to knock most of it out pretty quickly now it's all designed!

There was a video, but YouTube have blocked it on copyright grounds for the music on the radio that was playing in the background...

Thankyou!

The card was the first box I could lay my hand on in the workshop! I measured it today and it's 0.5mm thick. I also made the ribs on the cylinder of the Newcomen engine with it. The squares and circles were cut using the laser cutter, but I'm sure you'd find a leather punch that'd knock out the circles if you were to use the idea.

There's some wonderfully bizzare machines to take inspiration from in that period. That layout is a cracker, some fantastic details on it. That era is a very bright and colourful period, and everything is very pretty. Interesting to see widespread use of traversers in that period. I love the broad gauge on there too - would really like to run broad gauge in the garden! How I would love to see one of the replica broad gauge locos hammering down a good length of track!
