Hi everybody
The SE&CR D Class is now complete and painted. I will bring it to the Alton GTG and it will be at Sandown Park Dec 9-11 on the 2 1/2 stand. The ME articles are now up to part 3 in the present mag. And now for something completely different! My next loco will be the 1845 0-6-0 'Derwent'. I have a few photos but no plans so this will be the whole exercise as with the D. If anyone has any info on this wonderful old antique I would be delighted to hear from them. In particular I need a full frontal view and details of the boiler/firebox, valve system and controls. Also any ideas on how to make those wheels.

You probably have this link already - but for the benefit of others - the best photos I've found (so far) are here: http://www.docbrown.info/docspics/northeast/nutpage26.htm
You will need to page down a bit.
With regards to the wheels, apart from the obvious route of making a pattern and having six (and one or two spares?) cast in CI - I suspect it would be possible to fabricate them. I cannot quite make out the spoke profile but the inner strengthening ring is interesting.
Are the spokes "T" shaped? If so it should be possible to turn the hub/ring/tyres as separate components, mill slots in them on a rotary table and then lay in the separate spokes, truing the finished assembly after brazing/silver soldering.
Quite a lot of work for us mere mortals but I have great faith in your production capabilities DicK! :D
I assume this engine will also be gas-fired?
Regards,
Ian
Thanks Ian
I will bring my drawings of the wheels etc to Alton. Yes, it will be gas fired. Essential as the prototype was fired from the front! So external detail can be preserved by cheating and putting a ceramic burner at the back.
Dick
Dick,
YES, YES, YES!! That would be really interesting, maybe with a train of chauldron wagons? To match the original it won't need to have much power!
Mike
Hello Mike
Thanks for the encouragement, I may need some help with the wagons. At the moment I am concentrating on the loco and,thanks to Ian T, I now know why I can't get a good frontal view. The photos he linked me to have the front obscured by the coal wagon (which is of course, at the front). Do we have any members close to Darlington? I would gladly pay all expenses if somebody could go to the museum and get some serious pictures

Reference on RMweb suggests this book : 'Private Owner Wagons of the North East - volume one - The Chaldrons' written by John Elliott (published in '94). Full of usefull drawings for scratchbuilders.

Hi Andy
thanks for the links. The wagons look splendid. Only trouble is I might need 40 of them!
Dick
No problem. Make a wooden pattern - cast them in resin, preferably in one piece. They may need a load to hold the engine back.

Hello All
I belive I still have a friend up there , I will try and do some arm twisting . Re waggon , I have a copy of said book on the shelf .

I visited Darlington in 2006 and took a photo of Derwent. Its a bit of a three quarter shot of the cab end. Not a very good photo but it shows the weatherboard and cylinders end of the loco and some wheel detail. The file size is over 400 KB so it wont attach. If you e-mail me at david.crone@talktalk.net I will sned it on if that would help.
David
Thanks for the offer David
I do have some very good 3/4 photos from the back, those from Ian T's links are excellent. Those from the front quarter are all obscured by the coal tender at the front. The particular ones I am after are 'boring' things like the way in which the wheel bearings are joined to the boiler. There appear to be no stretchers joining the frames across. Also I need pics of the valve eccentrics, gabs and control links and a close up of the front end of the steam chest.
Dick
Dick,
I think you would learn a great deal by actually going there. It may not have plate frames at all as bar frames were usual at that period, and continued by the Americans for a long time. The "stretchers" could therefore be very small in section and its only the whole structure that gives any rigidity at all. And even then they doubtless flex.
Mike
Hi Mike
It's such a long way away! I do have a very good book by Tom Pearce and several drawings and there are indeed side frames that dip at the back in order to come down to the level of the water tender 'buffer' bar. The bearings are mounted on 'squashed box' sections rivetted directly onto the boiler. I wouldn't want to do this on my model so I will try to introduce some stretchers at the same time as preserving at least the appearance of the original structure.
Dick
Hi All,
The S&DR Detrwent is now finished and I plan to show it at the ME Sandown Park exhibition. I am now moving on to the Chaldron wagons. Andy kindly sent me a drawing of the Seaham chaldrons but they are not quite tthe same as those from Beamish or other suppliers to the SD&R. I've designed a compromise and attach a drawing (2 parts)
