Hi John, don't have any worries about Phoenix paint, I used that exclusively when I rebuilt my Torquay Manor over 10 years ago, SNIP Chris Hi Chris, and thanks for that reassurance. I've used them many times: if only they weren't so grumpy! There's a new girl who talks about 'selly' aerosols. I don't think she knows that it is really called 'cellulose'... John |

Hi John,
Very pleased to here about your purchase, and that it is going to be a 'runner'. I do like single driver locos.
I don't know much about the Scarth Reeves loco, but from one of your pics, the smokebox draughting could do with a looking at, and pleased to help out if you want to go down this road. My initial thought was that the builder had fitted the cylinders 'upside down', but I have never seen the Scarth drawings.
I can see at least 3 crown stay rivets on the top of the outer firebox with no silver solder penetration, and the backhead has no stays around and above the firehole. The staying distance with what appears to be comsoled threaded stays seems to be me to rather generous. No longitudinal stays, not that I consider these of any value, but I would be surprised if the Scarth drawings did not have them - which leads us down an avenue of a boiler not built to drawings possibly?
I note a smear of comsol over the joint between where the barrel ends and the outer firebox starts presumably over an internal 'piston' joint, which would give me concern as to the original silver soldering of this joint, though everything else seems to be very well silver soldered from your pics. I would quite like to see a pic of the throatplate joint and a pic of the inside of the firebox.
If you have no previous boiler test certificates of this boiler, then some clubs would take a very strict view on this boiler. Others will not, but it only takes one faulty joint to suddenly come apart. These things do happen, despite surviving a rigorous hydraulic test.
Query - why has apparently comsol been added specifically to the barrel to firebox presumably piston joint as opposed to a butt joint? I would not want to see comsol here at all. I would want to see a decent fully silver soldered joint all round here and the barrel to throatplate joint, and no sign of comsol on any part of the foundation ring either.
Cheers,
Julian

I’ve found the same with Phoenix Paints the father or father in law seems very helpful but when I have seen the son who owns it at exhibitions shows all he has done is sit in a chair looking completely disinterested and not interacting with anyone.
On another note showing my ignorance here on my Stirling there are two vertical cylinder/tanks under the footplate and I don’t know what they are or do. The larger one has a valve at the bottom with a log handle and wheelhead which extends at an angle from below the buffer bar for adjustment. I tried to attach pictures but can’t them to upload. Can you tell me what they are from my description?
Thanks Glyn
Silly me they are connected to the brakes! I am getting some drawings so perhaps I won’t be so green

We've been here before. If its to the published drawing then thats it, regardless of whether it would have been nice to have a few more stays or not.
I see the coloured mark you seem to be referring to on top of the barrel/firebox joint, but its a bit of a jump to assume the prescence of Comsol and the reason for needing it. Even if it is, theres nothing wrong with Comsol for caulking pinhole leaks. Its had a pressure test to 200 psi, apparently without any signs of distress, so, there should be no reason we know of at present why the club tester should reject it.

Not much progress as I've been busy elsewhere. I'm also finding niggly little things, like the broken 10BA tap in the hole for the reverser handle! I need some more castings: i.e. tender axleboxes and splashers, and also the safety valve cover - 2.5" high and much the same at the base - at a mind boggling £56.41! Looking under my bench I found this very ancient 4lb brass weight which is absolutely ideal for the safety valve cover.  The others will have to wait until next month...

Safety Valve Chimney/Cover
Whilst waiting for some bits I thought that I would get going on something potentially beautiful!  Make a simple gauge out of a scrap of fibreglass.  20190729_173922 by inkaboat, on Flickr Taking off the rough stuff. Notice Steve's swarf guard!  20190729_170942 by inkaboat, on Flickr Profile by eye best you can!  20190729_175619 by inkaboat, on Flickr Bore 3/4" for the mandrel.  20190729_181109 by inkaboat, on Flickr It fits!  20190729_182720 by inkaboat, on Flickr More tomorrow: I'll probably use a scraper on a hand rest, al la woodworking, to achieve the final curves. John

Looking very good, John. Regards, Steve Looking even better, Steve... All I have to do now is profile underneath without ruining it! John  20190730_160832 by inkaboat, on Flickr Here's my very short video on hand profiling in the lathe. I hope you all find it useful! youtu.be/vo3NMaaU5d4And a quick preview. There are still some fine scratches that I hadn't noticed, so back in the lathe tomorrow.  20190730_161737 by inkaboat, on Flickr |

Ready for fitting to the Safety Valve.It's my 72nd birthday tomorrow, with a barbecue party in the afternoon, so I thought that I'd better do a little more tonight as the morrow is a little unpredictable... Scratches removed, buffed to a lovely sheen - I knew that 12 years of Army bullshine would come in handy one day - and the underside is ready for milling the 2.25" radius. I've left a little meat on it, as if the section is too thin then any cutter will get under it and the whole thing goes for a ball of chalk!  20190730_223755 by inkaboat, on Flickr

Hi John,
Happy Birthday!!
the cover is looking lovely, but I am wondering if it will look correct with the radius just milled out of the bottom? if you look at pictures, they are like domes and chimney bases with a flare which varies as you go around the base.
Can you machine it thin enough so that you can persuade it with a soft mallet?
Chris.

Hi John, SNIP Can you machine it thin enough so that you can persuade it with a soft mallet? Chris. Hi Chris. Yes, I've been thinking about that and I'll look at it after my birthday party... On reflection, I did the Brit chimney by leaving enough meat on it after machining the radius to file it in the lathe to produce the flare. We shall see... John |

Hi john, Happy Birthday by the way 🎂
I shall have to profile my dome to fit the cleading (when will the bloody paint dry?) I thought about a free hand profile but chickened out after watching this thread I think I’ll revisit the issue. Looking forward to seeing how you profile the base....far from a ‘simple’ loco..
Cheers

Filed it after thinning the bell to 1.5 mm. thickness.  20190731_113237 by inkaboat, on Flickr Whacked the lips on a former with a nylon hammer, just like Chris said! I then took a 2lb hammer to the arbor which formed it nicely...  20190731_122842 by inkaboat, on Flickr A good result. Not quite perfect, as there are still plenty of marks in it and the bottom lip needs fettling, but I'll finish it when the cladding goes on. Time for a soothing ale as it's my birthday!

Happy Birthday John, looks like you had your birthday present a week early. I’ve just obtained copies of the Model Engineer issues by Martin Evans on the Stirling 2-2-2 for reference. I am currently trying to figure out the steam connection to the cylinders as mine didn’t any superheater pipework or headers supplied with it and no evidence of where it was fitted. Is it conceivable it wouldn’t have ever had them fitted?

Is it conceivable it wouldn’t have ever had them fitted? At that time, wet steam ruled OK, so no superheaters. I have those articles, but I am not going to bother with superheaters with mine as I'm not interested in IMLEC... John |

Hi John,
Nice result on the safety cover. I think after that 2 ales maybe required....Happy 72nd.
