Hi Malcolm, SNIP I think that I would just temporarily remove the superheaters and fit blanking caps to the connections on the wet header. That way it won't matter if the regulator weeps slightly when you test. SNIP John
That what I did on my Stanier, because like Malcolm's engine, my regulator weeped slightly.

Thanks guys for all the useful suggestions.
Your time and experience is much appreciated.
This morning I spent 3 hours removing the smoke box and saddle tank. I can now get at the steam feed into the valve box(es). I intend to turn up two blanking plugs and test regulator,super heated steam pipe and return tubes where they enter the valve block(s), all at once.
I hope it all goes back together!
cheers
Malcolm

Hi Malcolm,
I haven't yet reviewed your thread and in particular the pics, or our email stuff.
I may or may not (probably not as you had already made all the bits) have expressed my own personal view that the 2 steam pipes to the 2 cylinders is a bit of a 'dogs dinner' by Don Young. Exactly the same arrangement was specified for the 1968/9 Railmotor design. I decided to have a central single steam pipe in the centre and front of the smokebox, easily accessible with a spanner from the pipe/pipes from the hot header - though I've never had a 'hot header' in actual fact.
The pipe connection to the central forward standpipe have flat connections i.e. a flat faced phos bronze 'nipple' on the end of the pipe from the superheaters to the stand pipe to the cylinders. An annealed copper disc can easily be added between same prior to an hydraulic boiler test in a matter of minutes.
I've never made a regulator valve that didn't leak on an hydraulic test.
Cheers, Julian

Funny you should be talking about leaking regulator valves. See my Terrier post and the troubles I am having on my Hunslet! Ed

Good Morning all In the unlikely event that you were wondering had I ever finished my Hunslet engine, well, yes I did. It only took about 7 years, so no truth in the rumor that scratch building a 5" engine in easy and quick!
It is now almost 2 years since my last post on this project. Attached is what is supposed to be me on the elevated track at the York model engineers track doing one of my inaugural laps. I may have lost the "motion" element of the video. Unfortunately due to things beyond my knowledge in Flickr and the transfer of video files between itself and Model Engineers Proboards. However you get the idea. It all works fine.
Why the two year gap I hear you ask? Well various reasons. I had started a 7 1/4" Ken Swann Bridget for one. A continually leaking regulator valve in the Hunslet for the other. I searched for some 'expert" to solve the problem and was guided to all sorts of people. As is always in life some were good at talking about it others could actually do it! Eventuality I went to Tim Jenkins of Rufforth Steam at Southport ( ex Steam Workshop) who had the engine for a few weeks and got it running smoothly. I would recommend him to anybody. Nothing too bad found but lots of little things that he put right including the dreaded Stroudley regulator. Being from a Tool Making background many years ago I had made the engine too "fine" and it was very stiff. Should have been more generous with my clearances. Will try and do better in future.
Back at Rydale Club at Gilling I had a lot of help and encouragement from Mr. Lin Bisgrove, whom I would like to thank publicly here for his mentoring. Without him I think i would have given up.
After a bit more fettling I got the engine through its hydraulic and steam tests. Upon completion of these tests We pushed it onto the turntable which has gauging blocks that comply to the Gilling GL5 standard loading gauge and guess what? It would not pass through the blocks. Result: I am not able run at Gilling!
To say i was peeved was an understatement. 7 years of subscriptions and no word from anyone up until that moment. Say no more other than to anybody else who is thinking of running an industrial NG engine at Gilling is don't bother or at least check the loading gauge requirements first.
What to do? Look for an elevated 5" track which Gilling does not have. How to do that? Go to the Model Engineering Exhibition at Harrogate where most of the Northern England clubs had stands and was literally inundated with offers of help. York and District track is almost equidistant to Gilling from my home near Thirsk and they have a 5" elevated track. Everybody was very helpful and I managed a lap of the track on the first day there. A little bit more work on injector feed etc and I was up and running. The attached video hopefully shows the evidence of that.
So back to the Ken Swann locomotive, which is coming along quite nicely. I will give occasional updates on another thread if you are interested?
Cheers
Malcolm
If you are running an Ad Blocker you may need to turn it off to run the video.
Tim Jenkins new address is Rufford Steam Works in Brampton near Carlisle (not Rufforth, my mistake) He is on Facebook.

Great to see it running, well done.
If memory serves me right the blocks on the turn table are same location/size as the point motor covers therefore if you don’t clear those you won’t be able to run out of the track. I may be wrong but I think it’s something like that.

Hi Adam
Yes spot on, that is the reason.
Cheers
