Girder Stays. Girder stays might look simple, which they are, but they can be a wretch to fit. Getting then to seat their full length on the inner and outer wrapper with the correct curve seems to take me ages. Never mind, I did it to my satisfaction in the end. So, I thought it time to do a Gresley V4 boiler update. Tubes to firebox this week, then I should be ready for the full assembly and the 'Big Heat'. Simon's making me nervous. Wish me luck JB. I like the globe valves, They'd look nice on a V4 backhead.

Cecil Pagets 2-6-2 of 1908. Engine number 2299. Would make a fascinating model....

Simon's making me nervous. Why What silversolder and flux are you using, you're getting some nice joins with it. Actually it would be nice to know this from everyone who posts boiler work photos to compare. Equipment used would also be useful, straight propane, oxy-propane or oxy-acetylene.

Long Story. Simon's making me nervous. Why What silversolder and flux are you using, you're getting some nice joins with it. . Simon - It's a long story. An old chap gave me a bundle over 30 years ago and said - ' this is what you need to use, it's like easi flo No 2.' I tried it on a test piece and then built three boilers with it. All three have stood the test of time and pressure. This label was on the bundle. I've never needed to buy any since. I've often wondered what he had it for. The flux is Easi-Flo as advertised for Easi flo No 2. Chris

Double Take. I put the flue tubes in today. I always think it's a big event. There's something psychological about it. It' a feeling of the inner firebox almost complete. But - not all went to plan. I took my time 'setting up' as you need to with the tubes, fluxed, vertical and the like. On inspection after pickling - one dry tube smack in the centre. I haven't had that happen before. I hate having to do a 're-do'. Look what it's caused - 'a blob' in the firebox. Over enthusiastic with the silver solder to make sure of getting the dry tube. Shall I leave it or grind it off? I've never looked closely at professional boilers, do they have 'blobs'? Chris

Looking good Chris. BTW, I rang Steam Technology this morning: they are working towards getting my boiler to me before Christmas as they have a lot of work to do after that date. I'd better tell Mother-in-Law not to come....... JB

Good News.
That's good news JB. No - tell her to come, she can keep the wife company and wash up. You'll probably be too busy for the domestic chores or socialising.

Bending Rolls. It's been 3 months since I last wrote to this thread. I even had to go back 6 pages to find it. I was beginning to think that a supervisor might have deleted it for inappropriate comments! I'm going to get back on the boiler this week having been distracted by a number of issues, such as - Winter servicing of the Simplex ready for another years trouble free running. And a new acquisition, that's taken up a few weeks for refurbishment, look - Bending Rolls, and just when I didn't need them, having finished bending up the copper for my Gresley boiler. Now - not knowing a lot about sheet metalwork, are these what are called Slip Rolls? If not, what are slip rolls compared to these which have 3 rollers. 2 for pinching and 1 for the bending of the material as it exits the rollers. Chris

Tempting glimpse of a B1 front end there Redmog, [ and a Border Terrier too] did the platework ever get finished or is that what the slip roll machine is for ?

Cab Roof. Tempting glimpse of a B1 front end there Redmog, [ and a Border Terrier too] did the platework ever get finished or is that what the slip roll machine is for ? Ian. Yes Ian. I'm going to use it on the cab roof. I ran the loco for years without the cab roof because I never found anything with the correct curve to bend it around. I did the boiler lagging though, because they installed 'ramraid posts' at the local supermarket. I went round there one Saturday morning with a sheet of material, 2 G clamps and an overlength strip of 2" x 1/4" BDMS, and clamped it to the post and it bent round a treat. I don't know what the shoppers thought. It worked though, as can be seen. I must make an effort to finish it. Chris.

I'm not a sheet metal worker so I might be wrong but don't some bending rolls unship at one end to allow you to easily remove something like a tube? Are these types called "slip-rolls"?
John.

Nice story attached to the forming of the boiler cladding Chris, a touch of eccentricity in all of us methinks, gives the natives something to talk about when they're doing their shopping. Nice looking B1, time you were finishing it [sez he who has about 5 unfinished projects on the go !]

On Track. I've been fabricating the saddle over the last few weeks in order to line the boiler up to centre height ready to continue with its build. The parts are loosely assembled so I couldn't resist taking it down the track, before the rivet counters turned up, to give it a push along. It's got a great 'chuff chuff' even though the blast pipe hasn't been leveled to the correct height. Ready to continue with the boiler now. Chris

Chris I did the same thing with the Brit chassis: I couldn't resist pushing it along the track and listening to the valve events. I was well chuffed too! JB

Nice looking B1, time you were finishing it Ian. So I dragged it out today and tried out my new acquisition. The bending rolls. Amazing how a new toy can motivate one into getting on. It bent up some 16g with no trouble, and a nice even curve too. It even bent up some 5mm square BDMS with ease, which is the front inner attachment strip. Just had to try it in place and stand back. Looks about right, all I need now is some B1 cab pictures to copy. I'm getting off topic, so I should get on with the V4 boiler. Chris

JB's Rivet Counters. Rivet counters, laugh. I've machined my hinges off JB. It's too difficult to get the sharp edges when they're cast in. Well, it is for me. I had to make my hinges from copper, silver soldered to brass, because the somkebox has such a convex surface I needed a malleable material to allow for the double curvature. I've still to make the hinge pin, stainless I think. Nice to see you back! Chris

Great workmanship there Chris, I like the perspex valve covers.

Nice hinges Chris
I did think about copper but I felt that the way the door gets abused when cleaning the flues, that it might flex and crack the paint, so I went for well annealed brass which is now quite stiff.

Perspex Valve Covers. Great workmanship there Chris, I like the perspex valve covers. ace Thanks ace. I'm waiting for some brass plate to fall my way. It's nice to be able to see the valve events though, without the concern of anything dropping into the cylinders. I was thinking of leaving them on, for when I try it on air. The cylinders still have to 'come off' for the cladding and drain cocks. Chris
