Black 5 Boiler problems

If threads don't seal how do tapered threads work

Stan

[David WassonParticipant @davidwasson11489]

Hi Stan,

Ah yes, of course tapered threads! I am pretty sure we are talking about straight threads on boiler bushings and fittings. Of course, there may be some that are tapered, but, the majority are not. Tapered threads are of course specifically designed to screw tight into each other, even then, some sort of sealing compound is used.

Other places where there are in fact no "screwed fitting" would be at the regulator and at the inner dome bushing. These depend on sealing only by the circle of screws and the flatness of the fittings, and perhaps with the help of a gasket.

Hi all well thank you again I never tried to see if the mating surfaces sealed as GB Boilers had so hard problem trying to g them to seal did not want to take the chance of them leaking.

I used gasket paper on the joints on the flat surface used the copper silicone on both faces then used the bearing seal on the threaded part.

As a novice trying to learn from so many mistakes trying to avoid problems to save headaches later.

After stripping it down so many times because of the boiler leaks I have had many weeks of thinking and so many suggestions I have tried to work out what would be best for me.

I am just hoping I have gone down the right road as I have made all new fittings and pipes taking extra care to get as good as I could do.

Going to try fit the boiler Lagging and cover today and do some final checks before taking to club Sun to do final test see if all is ok.

Getting exited never thought I would get this far so soon as did 10 hours yesterday and about 4 wed

It would be real nice if I could put the boiler into the frames on Monday if all goes ok Sunday.

Many thanks

Ron

Getting worried it's all going to easy I know I have had to strip it down many times but it seems like clockwork to go together this time.

Keep wondering what will go wrong I hope I really are this lucky this time as I thought it would take about a month to get this far.

[Ron HancockParticipant @ronhancock63652]

just put a thin coat lacquer and got a run oh well if that's all that goes wrong bot worried polish out when dry

[Ron HancockParticipant @ronhancock63652]

Well today is a good Day I fitted super heater then back head fittings only leak was very slight from gauge glass.

They took it up to 135 so now I can start to fit the boiler.

I just hope not too many more problems be nice if I can get it done for We'd so I can do the steam test.

Thank you all for the help getting here you have been a big help

Happy Easter

Hi Harry yes so many problems with new Boiler now hoping they are all behind me.

Just taking my time I fitted the Boiler today and piped up in the smoke box.

Tomorrow got to make the pipes for injector blower and whistle

Then fit ash Pan and the cab and dare I say put a fire in.

The first couple of times going to let it warm up very steady get it to about 30 let cool the relight give the new boiler time to harden and bed in.

Then try and see if it will raise steam if it does back to the club we'd and get steam tested fingers crossed but don't think it will be that simple bound to be a few more things to solve but feeling positive now it's got through pressure tests 3 last wed one today

Ready to put fire in to slowly bring up to temp ready for steam test on Wed let's hope all will be good.

[Peter KroghParticipant @peterkrogh76576]

That's really great, Ron! She's a beauty.

Please do me a favor and get some outriggers under the ends of that. I'm worried sick it will fall on you!!

Cheers

[Ron HancockParticipant @ronhancock63652]

Thank you both tried to raise steam but found a small leak on steam pipe to cylinder should be easy fix.

Just sorting my friends super Simplex several threads stripped so remaking for him

[Ron HancockParticipant @ronhancock63652]

well STEAM UP FAILED THE EXPRESS SAFETY VALVE BLEW OF AT 45 PSI AND ALTHOUGH BOUGHT NEW LAST YEAR CANNOT ADJUST.

TRIED USING CIRCLIP PLIERS SOLID WILL NOT MOVE DOES IT EVER END

[BC ProfParticipant @bcprof]

Ron,

You may find that the very top of the safety valve is shaped as a collar. On mine you need to undo this a little to allow the inner section to be adjusted with circlip pliers . A bit of a fiddle but at least the workshop mice can not adjust them when you are not looking .

Brian C

[Ron HancockParticipant @ronhancock63652]

Hi Brian i have managed to undo one by undoing the top first.

the second one just would not undo it just chewed up waiting for new one from Polly.

just hope when i get pressure up not to many more problems.

Ron

[Ron HancockParticipant @ronhancock63652]

Well I have let myself down fitted new blower tube without silver soldering the one end. The tube screwed into one end fine then after fitting the other end on it just pushed the other end to screw further and never screwed into the T piece so when steamed water just came through the blower holes so no steam test. Just going to fit new pipe and fittings and this time pressure test it ??

Ron

[Brian HParticipant @brianh50089]

I don't know what to say Ron except that you cannot be far off reaching the end.

Wishing you all the best and some better luck.

Regards

Bran

[Ron HancockParticipant @ronhancock63652]

Well still not steaming as yet but getting very close took loco to club and re plumbed the tender to loco for the first time. I tried to steam but one clack valve would not work and its new so i have ordered two more this time from polly at Notts. Hoping to steam her Sunday it went through another pressure test all was fine this time. I have also ordered a new no 3 injector as the one from Reeves 2000 playing up. hope by Sunday might be able to finally run it. Ron

[Ron HancockParticipant @ronhancock63652]

[Ron HancockParticipant @ronhancock63652]

[Ron HancockParticipant @ronhancock63652]

Finally back together except for new clack valve coming tomorrow. Hoping it will steam OK Sunday.

After so many problems it feels great to see it together again hope not to many more problems when I do steam test.

Had a lot of help from club members sorting my Tender piping out.

Hope it does not rain Sunday now but still going if it does.

Thanks every one for all your help getting here one happy novice here

Ron
