Not a lot of modelling over the Christmas period, though Brighton Works has been successfully commissioned (though the Peckett requires a bit of remedial work to make it run as well as I think it should).
Anyhow, another year, another Sentinel. You may recall my - rather involved - conversion of a pre-war 200HP loco built for the S&DJR into a post-war machine (here's the finished result if your memory need jogging:
4mm - The Sentinel (and derivatives) in EM - overdue update). This one is the smaller brother, a post-war 100HP loco from RT Models (with drive unit from High Level) and has, so far, been a complete delight to build with every part fitting exactly as it should and, because it's etched in Nickel Silver, nice to solder, too. There's an account of an build if this same kit on the other channel:

I'll be basing it on one of the Roads Reconstruction (1934) fleet used in the precursor to the massive Whatley Quarry. There are plenty of pictures of these about so here's my personal favourite collection, from 1967:
Vallis Vale Somerset
The chassis unit is mostly invisible and folded up without fuss. The gearbox and swinging gear train was a mite fiddly, but results in a smooth and
very slow-running loco (but the real thing is only capable of 13 mph). Despite this, the flywheel does have some effect and once fully weighted, I'm hopeful that the thing will be relatively powerful - unweighted trials had it pushing 8 wagons perfectly happily.
Thus far the only alteration I've made has been a cosmetic one. Sentinel made their loco steps from Durbar plating so I've added an overlay to represent this (the etch came from Intercity Models, I think Shawplan may do something similar). These Mendip locos only had steps at the rear...
So here's the body assembly thus far:
And finally, for now, body popped on chassis to check clearances. What this demonstrates is that there's plenty of room for adhesive weight when the time comes. The coupling hooks are from AMBIS - I think they are slightly overscale for usability, but the tininess of the loco accentuates this a bit (nothing wrong with the hooks supplied on the etch, by the way, it's just that I had these made up and ready to go!).
