I started work cleaning up the 3D print lines which were quite pronounced on the boiler barrel and fittings, in the end I decided that it would be easier to replace the whole thing with a new scratch built part. I had a rummage in the box of bits and found a smokebox of almost exactly the correct size which I think is from a Parkside Dundas Hunslet kit. The steam dome is a Hudswell Clarke casting from RT models, again almost perfect size and the sand dome I suspect is a Langley WD Hunslet one. The boiler barrel itself is a section of plastic radiator pipe cover from B&Q.
Once I'd done a bit more filling and sanding I started adding details to it. I've used one of Mr Ts couplings for the front because with such a large over hang I suspect that my curves might be an issue. Other than that I've used bits of fuse wire, styrene and brass wire to add pipework and so on. The whistle is from a Minitrains F&C body which I used the chassis from and is perfect for the job.
This was the state of play this morning after adding a whitemetal cab roof last thing yesterday. Normally I replace these with styrene but the weight helps to balance the smokebox casting. The tender is also in evidence which I've built pretty much as intended. (First time for everything.) The other Hudswell Clarke is stting in front of Island as I've just fitted a lovely lost wax casting of a reversing lever instead of the rather unsubtle Wills signal box lever previously there.
Some more primer next and I can't put off doing the chassis mods next...
