Thing about Baker's Fluid, unlike a lot of other fluxes, if you overheat the metal a bit it does not burn and leave a mess. Very easy to overheat using a torch.

Thanks for that helpful clarification about not leaving a mess due to overheating and the earlier rust warning. I will order some up for future use.

Thanks all for your advice and encouragement. What ever I do the beading does not look right and I think I did it in the wrong order, in other words the decorative rivets should have come last as they are in the way. The existing sides are now such a mess that I am starting again with the windows and the beading first a la greenglade's bog. As well I can now include the bent over top section that fixes the cab roof in thicker material and screw the roof on without nuts and bolts, just the bolts. And I might add I have been taught how to drill holes in a straight line, not an almost straight line, that might help too! So here goes, cabside 101. Cheers David

Update one done, looks good, happy, but look at this A2 Cab by David Goyder, on Flickr Once in a while one finds a photo. Here is the beading rivetted on. One is tempted to add the first window, it looks so good! This is typical Coleman and although a Jubiliee, it has all the detail of a Princes Royal including the vacuum pipe down the side. On with it tomorrow! Cheers David

What an atmospheric picture! Not sure what that "lump" in the cab side (above the figure 3) is, though....

After much agony, have got it as good as it is going to get. As Coniston said yesterday, a few coats of paint and flashing by at 60 mph who will notice!!! Left side done, right hext and then all those blasted rivets!! IMG_2443 by David Goyder, on Flickr I would guess the lump on the cab side could be a token exchange holder for single line working. Cheers David

Cheers David I'm having exactly the same problem here, LOL! Trying to solder the half rounds onto the cab sides of my B1. Solder went lumpy, so going to try some thinner stuff when I find the motivation!

Dear GWR I have rivetted most of it all around with 1/32nd rivets. Some years ago a old chap was selling bits and pieces and I bought a pack of 1/32 drills more out of pity for the man. I will never use these!!! That is until a day or so ago and I had some small rivets from my Dad's gauge O days so I gave it a go. Used an optical centre finder/ punch for the hole. Well I am a hero, in my workshop anyway, population 1! Then put correct it fluid around the outside, painted on liquid solder/ flux, applied a little heat from the chef's souffle torch and by some miracle it all went as it should. Model enginering can be quite fun occasionally!!! Cheers David

Cheers David I think you might be right but it looks like the remains of the device. I am not sure that Jubilees were normally fitted with tablet catchers but that particular Jubilee was shedded at Carlisle Kingmoor and therefore would have been used on the single line section from Dumfries to Stranraer. They were superceded by Clans. Geoff the Clan builder will know for certain. I am positive that Princess Royals were never fitted with tablet catchers so you don't need to worry about that lump !

I had hoped to use rivits too, but I only have 3/64 ths, and rather think I would break the beading, let alone the drill going through the platework! Trying again tomorrow, as I need to be undisturbed for some time before I attempt it, haha. Geoff

An alternative to rivets is brass BA screws, going back a few years, perhaps 10 years? I did my tender beading ( and later the large cab beading) using long 14BA brass screws/nuts. I found then easier to use than small rivets and just cut them with snips once tightened.
Looking great David...

Thanks chaps. Having had my hour in the sun, I should add that this has been the combined effort of 'Simplyloco', solder and rivetting suggestions, greenglade for his writeup (read it more than once), jock for his encouragement (and all the cast and crew on the producton)!!! Cheers midland

Progress! IMG_2452 by David Goyder, on Flickr Joining the cabside to the spectacle plate was impossible until I found some 12 BA hex bolts. They look like rivets from afar and did the job. And since Simplyloco made a whistle, so did I but this is a Caledonian hooter! Cheers D

Now planning the painting, time to pull in the big guns as in 'Simplyloco'. But looking forward to painting the Aspinal one day, it is black all over and everywhere not like this bloody red thing with gold lines everywhere!!! Well it was an adventure! Cheers David

About That trim piece on the front of the cab... did you use a combination of annealing, stretching, and thinining, of the metal flanges at the bends, to achieve that wrinkle-free section? Quite a complex curvature, it is. of course, the right half, to be it’s mirror image! Very nice metal forming! The Thin gauge stock takes but little thinning, before being too thin! The fine art of metal bashing !
Nice work, there, David! It really does, require a good “squint” to see those wee Capscrews! Specially as shegoes frying by at 60 miles per!
Yes... Smashing is the word!

Mick The angle in front of the cab was formed by a bit of messing around. First time I was annealing it and got it too hot and it drooped. Binned. Next time I drilled the holes and then tried heating and got several straight short bits broken at the holes. Binned. Last I heated gently and manually bent it around the handle of a little hammer I use. After heating and bending it took up the correct shape. Then I drilled the holes. I was quite surprised at how easy it is to bend the brass when it gets red hot but not too hot as it turns into toffee!! So we live and learn. If nothing else this Princess Royal lark has opened by eyes to a lot of new skills that proper engineers have known about all the time but us lot have to learn about. Now onto the red paint experience as they say!!! Cheers David
