Thank you, all
It’s been an enjoyable exercise, and a side benefit is the Tiny Train Room is a lot tidier now
Cheers

Good stuff Jan
Your efforts are giving me deja-vu

Thanks @Jim smith-wright
Along with Matt Owen (and the donation of the weight and pulleys from Ernie Puddick of The Clearing House FB group) your model is one of the inspirations for my attempt.
Cheers

Petards, and the scale hoisting thereof..
The affliction/affectation/downright idiocy continues. The latest outbreak found me trying to fathom a way of representing the teeth on the hoist. I tried to lay individual 5 thou ‘teeth’ without success (this was based upon my calculation of 184 teeth in a 2ft diameter… ). I did succeed in thickening up the base of the gear though. I drilled a hole in some 20 though plasticard, and fitted it over the ‘drum’ before we filing it to the same ‘circumference’ (the Triang basis is not circular, it turns out…) as the original. After that, I wrapped it in a layer of 5 thou.
I subsequently tried with some Evergreen rectangular strip laid “off site” on a 0.005” sub-base..
There was a deal of shenanigans with glue type; Plastic Weld is as a Velociraptor to Robert Muldoon, and Superglue is too unforgiving. I tried later with Rokot Glue, which has tackiness, but it’s almost too fluid!
After that (I may yet revisit it…) I made a skew gear (just a representation, as it’s entirety is hidden in the side view) and another drum for the hook lift (and here, I’d ask if anyone has any pictures of where all the wires go once they enter the framework, I’d be ever so grateful - Paul Bartlett’s site and Flickr have proven helpful, but the last few feet aren’t to be found anywhere, it seems).
Then it was out with the saw and soldering iron to reduce the length of the Triang brass pivot pin (the plastic extrusions holding it were one of the first victims of the cutters torch). From this:
… to this…
… held together with a 0.4 mm NS pin, and Carrs 188…
After all this, I couldn’t resist another fitting.. it gives me a boost to see it coming together.
Next is the cross-member above (and slightly behind) the jib hoist drum, a representation of the various gears below the drum, and the fitting of the weight…
