Thanks John and John.

Yes I did go for a lie down after making and fitting the rear irons. To be honest it wasn't as bad as I thought it would be. I found drilling the hole in the 1mm strip the most challenging part, but once done you bend the strip into a L shape, solder the wire in. File the wire flush with out face of the iron and round off the ends and fit to the bunker. I used a high temperature solder to make the iron and then a low temperature solder to fit them.

I haven't forgotten about the brake release spring, but thanks for letting me know that they were on both sides. I have some more detail bits to fit to the chassis as well as the brake release springs, like the front sand boxes and ash pan bits but yes it's all coming together now. I'm saving the ejector and motor train thingy me a do da to last.

All Best

Hi All.
I've fitted the front lamp irons as you can see from the image. You will also see that the handrail knobs I used for the smokebox are different. I used the ones supplied with the Craftsman kit but managed to break one when fitting it. I replaced it with a Gibson one but didn't notice the difference when I fitted it. It was only when I took this image I realised they were different. If I've got a spare one of the original type supplied in the kit I'll replace the Gibson one as I only soldered this in place using low melt solder. If I have to replace the original one this will be more of a pain in the butt to do.

The other images show the steps fitted and the pipework under the running plate. Now to tackle the buffer beam details.

All Best

Dave

A little more progress. Tackling the front and rear buffer beams.
The buffer beams are quite a crowded place and fitting all the gubbins around the S&W couplings make it even more fun. I'm using MJT brake and steam pipes but decided to make my own pipes and just use the hoses. The pipes were made from 0.8 brass rod and used a brass washers to indicate the join for the top bent portion and a bit of brass tube to add detail where the hose clips onto when not being used. I made the pipe support bracket out of scrap material. Still got to add the electrical cable and cradle.

More going on with the 1P.
Finished all the brake pipes, steam pipe and the motor train gubbins. Pleased with the result but wish I had made my own hoses rather than use cast ones. I don't know if I've cocked up or it is a sort coming with the kit but there wasn't much of a ledge between the rear of the bunker and the edge of the footplate to fit the support plates for the brake pipe stanchions, so I had to bend the plates at right angles and solder them to the rear of the bunker. It was a bit of a challenge fitting it all as well as the S&W couplings but I got it all in and working.

All Best

Dave, the only photograph of which I'm aware that shows the rear of 58047's bunker with reasonable clarity is at page 57 in Norman Lockett's 'The Somerset & Dorset Railway 1935-1966', and was the guide for the setting up of my own model as shown here:
58047 rear.jpg
As you say, the running plate only protrudes a short way beyond the rear face of the bunker, and I simply filed indentations in the running plate to permit my pipe stanchions to lie flush with the buffer plank - didn't go to the trouble of providing the support plates you mention, as they don't seem prominent in the Lockett picture. For the motor train jumper cable terminals I was able to sweat a small plate to the top face of the running plate without having to extend it up the bunker, but I remain dissatisfied with my representation of the terminal screws - hoping the custom etching I've done for 58086 will represent these better.

Looking good; now on to the vacuum regulator casting on the smokebox side and associated plumbing, and stand by for squalls. I think that the best way of securing the brass turning I used to represent the casting was by fitting a peg into the back of the turning which fitted a hole bored in the side of the smokebox; this way you get a really strong fixing for the component which makes attachment of related plumbing at a later stage easier.

Does it have to be 58047? There are several rear views of this class in Locomotives Illustrated,No. 138, including one of a PP-fitted engine.

Thanks John. The finishing line is in sight now. When I start the next one I might try and extend the rear of the footplate. I was thinking cutting the footplate where the slots for the rear bunker are and soldering in a slightly extended piece. You can add some support underneath the foot plate at the join without it being seen.
I'm about halfway through making the ejector and then onto the brake thingy me-do-da.

Thanks Daddyman, any images are welcome of a loco but they all have slight differences etc. I was lucky enough to be given some images of 58047 whilst on shed at Highbridge. They give a all round view of the loco but sod-law never the the bit your trying to model. LOL. Here are a couple of examples.

That looks like an odd one judging by the LI photos. Yours seems to have a plate bolted to the face of the (wooden?) buffer beam, flush with the top of the footplate, so that there's no footplate overhang at the rear. Most (?) seem to have a little overhang of footplate over b.beam.

Best rear view I've ever seen of 58047! Wish I'd had that one when building mine.

I too was surprised by the sight of the apparently separate plate on the top of the rear buffer beam, and decided to look at little further. The GA drawings for the 1833 and 2228 classes show the running plate extending over the buffer beam and protruding slightly beyond it. I don't have a GA drawing for the earlier 1532 class, of which 58047 was a member, so was obliged to rely on what could be seen in photographs. There's a range of these in Volume 3 of "An Illustrated Review of Midland Locomotives", but they don't greatly assist in clarifying the extent of the running plate, since at least two shots (Plates 30 and 33) seem to show separate plates atop the buffer beam, whilst other pictures show the runing plate extending slightly beyond the rear face of that beam. I had speculated that 58047 might have acquired a replacement strip over the top of the beam as a repair following some minor contretemps, but the fact that two other members of the class seem to have an identical strip tends to suggest otherwise, and the possibility of a change in construction practice during the course of the class' manufacture.

Perhaps there's a Midland expert around who can shed further light on this?

Hi All. Just finished making the ejector thingy for my 1P. I think it turned out quite well even if I do say so myself. Made from basically for a lump of white metal some cooper and brass rod, etched washers, handrail knobs and the only part from a kit is the etched plate where the pipe enters the smokebox. Only problem was when I fitted the pipework onto the smokebox it must have moved before the glue had gone off and so sticks out a little. You can only see it when looking down from above. I tried to realign it but ended up braking off the little stub. This was soldered but I didn't want to risk trying to resolder it back so I just glued back into place.

Next up tackling the brake vacuum thingy on the other side of the smokebox.

All Best

Hi All. Another thrilling installment of my 1P build.
Made and fitted the Vacuum Controlled Regulator apparatus {not the brake vacuum thingy}. I really enjoyed making this bit of kit even though I had to make the main cylinder twice as the first one was about half an mill to short. Even though I tried to make everything the correct size using the GA Drawings but when fitted to the engine the two tanks didn't quite line up. I had to make the lower vac cylinder support platform slightly bigger, this meant the cylinder stuck out a little further than on the real loco.

Before tackling the cab interior, I've got some little jobs to do on the chassis, like fit the front sandboxes, brake hanger return springs and some detail work on the ash pan. BUT THE ENDS IN SIGHT!!!

All Best

Very neat work on the VCR gear - far superior to the Bachmann moulded items on my Ivatt or the cast W/M items on my BR Standard 2 tanks.
Wonderful.

A wealth of delightful detail there, Dave - well worth all your effort. That VCR is a stunner......
Looking forward to your pics of the final result very much; keep slogging.

Hats off!

Well done, Dave, looking good. Whistle's turned out nicely too. Look forward to seeing her in mixed LMS/BR livery.
