The boiler manufacturer who made the boiler for "Lady Margaret" has declined to attempt a repair for the same reasons that we had anticipated i.e. it could cause leaks on the rest of the tubes and turn the whole thing into scrap.
Plan "B" is now about to be attempted. That is to get the tube as clean as possible using an acid bath and lightly grinding the joint then to use "Comsol" solder to repair it. Comsol has quite a high melting point (296) but not as high as silver solder (420+) therefore we may be able to repair the small weep on the one tube without disturbing anything else.

As well as our monthly meeting last night, we also had a guest speaker. We regularly have guest speakers at this time of year and the subject of the talks is quite varied and often has no implication to model engineering.
Last night's talk was given by a Physics teacher/tutor and the subject matter was regarding his visits to the CERN Hadron Collider.
He has been there a few times for various activities with students and gathered a lot of information regarding this facility.
I don't intend to even try to explain the workings of this unit as anyone wanting this information can access the site to gain comprehensive information.
Suffice to say that he kept the physics and science to a minimum and delivered a fascinating talk.Only one of our members was close to nodding off but he usually does.
If anyone is interested in this subject and wants to book this lecturer for similar talks then leave me a message on here and I'll get back to you. ... See more

We had one of our regular monthly meetings last night. On the whole,the club has been running well and our bank balance is quite healthy. The only problem that we have at the moment is a hydraulic failure of one of our steam engines.
Anyone visiting our home ground at Hurworth over the coming weeks or months will notice that "Lady Margaret" will not be available.
This engine was due it's hydraulic test and when the test pressure reached one and a half times its working pressure, a weep was noticed from one of the boiler tubes.
We have a lot of experienced members in the club and a number of them have built their own boilers in the past and it's hard enough to silver solder all of the tubes into the end cover with brand new,clean copper. This boiler is now 9 years old and although we could probably do a decent job of cleaning and descaling the exterior of the offending tube, it is impossible to clean the inside surfaces and the heat required for silver soldering will possibly melt the internal crud and contaminate the joint. We also know from experience that the temperature required to try and repair one tube can have a knock on effect on the adjacent tubes so that you are chasing leaks.
Our decision therefore is to consult with the original manufacturers to see if they can repair and certify this boiler. If this is not possible then we may have to purchase a new unit, bearing in mind that nine years ago, this boiler cost £1500. Hopefully with new technology and techniques it won't come to that.

We are running an electric engine at North Road Station Museum (Head of Steam) this Sunday 28th October at their Halloween event.

When you were a kid, did you ever want to drive a steam engine when you grew up?
Time and technology probably passed you by and your dream was never realised.
For most people, the dream will just be a dream but maybe we can bring a little bit of nostalgia into your life by allowing you todrive a model steam engine.
We are a model engineering society and our members build a lot more than just steam engines.such things as "pulse engines" "static engines" and even a working "Skeleton clock".
Hovever iy is fair to say that a good number of our members do build and run steam engines.
We are always looking for new members and you don't have to build anything to become involved.
We do have a comprehensive workshop with lathes, milling machines, shaper,pedestal drill etc and as part of "The southern federation" we are allowed our own "Boiler inspector" so if anyone is up for the challenge, then you could theoretically build your own engine on the club premises but it would take you a long time.
As a member,you could be trained up to initially drive our club electric engines and eventually our club steam engines. We are obviously looking for committed members who are willing to give up some of their free time to help us out on certain weekends with our portable track at certaib venues such as "North Road, Head of Steam" and "Shildon, Locomotion" museums.
If you are interested then pop down to The Grange on the first Sunday of every month or come down on any Tuesday night from 7pm in the basement of the Grange for a chat and a cuppa. ... See more

We are steaming this Sunday from about 10 until 12.30

We are steaming on Sunday at our home ground, "The Grange Community Centre" at Hurworth.
