Thanks Eddie....close photo's of this area seem very few..I'll go through my pictures again to see what I can find.. One difference that I did find tonight is the method of fixing the vacuum standpipe....I was going through the bits that I've already made and noticed that I had made a pipe clip same as fitted to the tender. At first I thought that I had got this wrong for today the pipe is held by a bracket thats attached by one of the board hex bolts. However on checking my photo's i can see that the clip is the correct method for my era.....I've noticed something else too regarding the bogie shields...I need to cut a small section of the inner corners......this new photo that I've recently seen is certainly showing some parts clearer than before. Appologies if this text makes little sense...using phone which makes things difficult to proof read...
Pete

Ok found some pictures showing the 3 hex head bolts Eddie, in fact, they can be seen in my avatar picture in it's original larger form. On reflection I think that I will still fill in the holes and just fit dummy hex heads, this will remove any damage from occurring when undoing the bolts to open the cover for maintenance purposes. The cover is a very good fit so I'm not worried about ash dropping onto the 2:1 gear from here and at miniature speeds not worried about it lifting at speed either. I can't do any work on the model today and not sure about tomorrow yet, grandfather duties both days but hopefully I can get it done Monday. Thanks again for the heads up Eddie...keep the info coming please, it's priceless....
Cheers
Pete

Evening chaps Lamp irons and grab rails The lamp irons are simple enough but thought that I'd share how I tackled these particular items as they are slightly different to the tender lamp irons covered before, hmm a god few years before at that... The iron's themselves are 3/16 wide and approx 1/16 thick but there's a little more to them than that as looking at my photo's there's a radius where the verticle meets the base which is wider than 3/16. I therefore decided to make the irons from 3/16 square bar and to file down the excess by hand, yes I'm a glutton for punishment... So the first picture shows the base section on it's side in the machine vice having 1/16 slots machined across it's back, note these slots are in the middle of the two mounting holes already drilled. I then cut up so oversized lengths of 3/16 stock for the uprights and silver soldered the lot together, this gives me a stick which is easier to work on, i also tapped any parts square that had moved during the heating process . next, I took a small amount of the bottom of the base to square the overhangs up so that I could hold the job securely in the machine vice. placing the job face down I machined the excess from the back of the uprights to just below 1/16 thick. with that done I then machined the tips so that they were all equal and finally machined the bottom of the base until I had an overall size of 3/4". with the machining finished it was time for a bit of filing, the first job was to tackle the verticle taper, it's 5/32 at the tip. I positioned the stick in the vice just below the top edge so that I didn't file away any of the metal needed for the radius. I checked each iron for a fit of the lamps, I'll go into more details about these later, when I convert them to working lights. getting closer to being finished, the base has been filed down leaving the radius at the bottom of the verticle and a slight angle to the tip. To make life a little easier for doing this I machined a shallow slot across a piece of hardwood that the base fitted into and used this as a guide as to how far to file each base down, still a bit sore on the old fingers but got there eventually. The finished article, the last job was to put a small radius on the end of each base. Last picture for tonight shows the lamp irons and grab rails fitted, the rails were made from suitable pieces of bar and tube which after bending was held in a jig for soldering together. I note in the picture that I haven't bolted the irons on squarely, I allowed play in the holes so can move them easy enough, will sort that tomorrow. The eagle-eyed amongst you will see the newly filed half circle out of the centre running board, this is for the vacuum standpipe which can just be seen in the bottom of the picture, this was made at the same time as the tender pipe, details of which can be found there. I'll cover this in the next update as it's fitted diffently today than it was back in the 30's. Thank's again to Eddie I also have three hex bolts to fit to the front of the 2:1 gear cover, I have already marked out roughly where these go, they aren't central as one might expect, I will try to remember to do these for next update. Thanks for looking Pete

Pete that's really neat and detailed, looking forward to the next instalment. If I understand the text correctly you are going to make the lamps work ?. If so then that has added interest for me as I have recently acquired a loco with a working lamp on the smoke box and I was wondering about adding some additional ones. Regards Paul

hi guys..... the lamps are from JCT fittings, picture attached to give details, Paul I have all that I need to convert the lamps, warm LED's, batteries and bulb holders. I will try to give full details when I get to it but this may be a way off yet. btw Ron, yesterday I saw a video that shows a quick glimpse of us two chatting at the Bob todd's memorial day 2015 NLSME track, posted by Brian showing a lap of his beautiful A4 'Quicksilver', it's on the LNER A4 group on FB. cheers Pete

Pete, many thanks looking forward to that. I have spoken to the supplier this morning, within earshot of the other half so hopefully like Ron I might be getting a nice surprise towards the end of December. Regards Paul

Please keep us posted on the success of your cunning ploy Paul. If it works I too have some little goodies I'd like to see in my Christmas stocking.

Just to finish off the last update, here's the front including the buffer beam nearly finished all but the hook and coupling. Standpipe is now fitted although I need to reduce the length of the vacuum hose to get the correct curve, a bit clearer in the last picture. I mentioned in the last update that the pipe is held differently today, the difference being that there is no longer an 'U' clip mounted to the buffer beam as seen in the first picture, today the pipe is held by a flat bracket coming off the top of the running board which is held by two of the hex bolts. I have adjusted the lamp irons as promised, fitted the standpipe, drilled/tapped the 3 10BA hex bolts (dummies so that I don't damage the paint needlessly) to hold the 2:1 cover and just for fun placed two lamps as appropriate for an express train. I did say that I'd do the working lamp conversion another time, however as interest has been shown and there may be presents involved I'll do this by next week to give a heads up on my method in a hope it's of use to others. I've already made a start but need some more materials to finish which are now on order. I will say as a teaser that I am very happy with the fit of my chosen LED and bulb holders, works a treat, more on that next week. I thought that I'd take another picture with the smokebox door taped in place to get an idea of how the front is looking, the door still needs a little work but it's close, I still need to make all of the hinges and dart gear too and as stated I need to reduce the length of the hose but in my minds eye I'm beginning to see a Gresley Pacific face taking shape.... regards Pete

It looks the goods Pete. Brilliant! The vac hose does look as it it bows out too far I must admit. I fitted a copper wire in mine to get the 'correct bend and to help hold it in place by reducing the load on the retaining fitting on the base of the stand pipe. It's the added detail such as the lamps and vac pipes that bring that authentic look to the model mentioned in another post. Looking great Pete.

Thank's Jim...I think once I've played around with it all will be as it should, I can't put wire in it as it's a working system, mind you, it's highly unlikely that a vacuum would ever be needed on the engine...not unless the folks at GL5 have a vacuum working turntable in development.... cheers Pete

I must admit I'd like to see it too. Cheers Jim.

Tempting Pete, very tempting, in fact it's set off some thoughts about displaying Boadicea when she's finished. Sitting on a turntable would facilitate seeing the other side of the loco plus I quite enjoy creating scenes...of the scenic type that is. Jim.

I would agree the John Tipton lamps are superb.
I had to make a non standard scale lamp for my 3.5"g Linda FR loco. Very fiddly.
John doesnt do LBSCR lamps in 5"g (which have a distinctive corrogated cover to the lamp) so unless John gets a bulk order or Adam is interested, I will have to tool up and make my own, and the LBSCR used lots of lamps and strange head codes!
Cheers, Julian

Hello Julian,
Have a look at the Allchin traction engine by Bill Hughes, he described making the lamps with corrogated covers, although for 1½″ = 1ft the lamps on a traction engine are considerably smaller than those for a locomotive, the manufacturing process is suitable for 5" gauge lamps. I think the late Bert Perryman made a set for his LBSCR Baltic using a similar process.
Regards,
Bob

Hi Bob,
Many thanks for the above. I have all the Bill Hughes series for the Allchin, but never took much notice of it - so perhaps I should have! perhaps a new thread on loco head lamps!
Until a couple of years ago my village was subjected to regular electricity cuts. I had of course a regular supply of candles and proper lamp oil (as opposed to paraffin) and it was rather nice to have fullsize loco lamps lighting certain parts of the house, plus old Welsh Miners lamps. Plus the glow of a coal fire.
Reminded me of the dark days of the early/mid 1970s when we had tilley lamps lighting the house.
But I dont want to hijack Pete's thread on the bad old day's of Edward Heath's premiership as PM.
Cheers, Julian

Has anyone made working lamps that use white or red LEDs and the sort of small cells used in watches? I'll be interested in having a go at that later. A high efficiency LED would probably last several hours on a small cell, and I'm sure it could be fitted into the body of a lamp.
