Thanks Kerrin. I guess it's the flexibility and coping with hot steam that are the issues. My Bantam Cock can be really cruddy after a good run, and I have never really found a good way to sort it out. All ideas welcome.
Nobbysideways - thanks for sharing your pic. If I had made that I would be very pleased with it. I dunk my small silver soldered bits in boiler descaler which brings up a shine on them.

Mugbuilder mentions he connected a suitable hose to the blow down valve outlet to steam clean his loco at the end of a run. I would like to try this but am curious as to what sort of hose is used. Any suggestions gladly received.

Looking at the data sheet it seems that 290 reduces to 15% of its strength after about 800 hours at 150 degrees. I am not sure if this is a constant 800 hours, but in any event my loco will have 30 hours a year at best, so it would take over 25 years to get to this point!
On the plus side it has a higher "melting " point than solder, and is as strong or stronger.

Hi Nobbysideways.
Presumably waterglass is also known as liquid glass, some sort of silicate mix?
I have heard of this being used a long time ago but I could find out a lot more about loctite.
Has any reader used waterglass?, and if so how is it applied and with what results?
Thanks
John

Thanks for your replies. It seems that 290 would better suit my needs this time as it is less viscous than 648, although the tensile strength of 648 is immense!
If I had a bigger gap to fill I reckon 648 would be the weapon of choice.
Once again thanks for this information.

I want to make a repair to a weeping tube on my copper boiler.
It is only a tiny leak, and I have read some posts on this forum that Loctite sucked into the gap with a hoover on the boiler would do the trick.
But there are a variety of loctite grades suggested, from threadlocking ones (290 etc) to fixing ones (600 series) and many stops in between.
I can see from some of the spec sheets that the Loctite solutions can be stronger and more heat resistant than ordinary plumbers solder.
My question is what grade has anyone used, did it work, and did it satisfy your boiler inspector.
Many thanks in advance
John

If you put cylinders on your tree would they come with packing?

A loo roll holder with built in drip tray.... You might be in to something there for us men of a certain age.

Hi. I had this problem once - a piece of gunk (presumably from the axle pump) had got lodged in the bypass valve so it couldn't be closed. It was a small , tiny, bit of stuff which I didn't notice for a long time. I cleaned out the bypass and hey presto all worked again.
Worth a try.

At Tiverton model engineers we held an outdoor committee meeting at our site, all sitting well distanced and bringing our own refreshments.

I have a friend who works in the aerospace industry. He tells me that most of his work these days is in imperial measures to co- ordinate with the Americans. John

My Bantam cock has slide valves and no drain clocks. I run it backwards for about 10 metres when cold, then it is OK and the cylinders are warmed up. Slide valves will lift to let the condensed water out. A nice to have but not essential if it is really difficult to fix.

There is a club near Perranporth I think called St Teath, it is a ground level track. I am a member of Tiverton model engineers who operate all year round from a site on Exmoor near South Molton. It's a lovely club, but I might be a bit biased!.

Hi. I have just had a similar problem with a Butch loco. It “threw” all the water out of the boiler in about 10 meters. A bit scary - dump fire etc... Investigation showed the regulator valve was not seating properly. Mine is a flat valve, held against the other face with a spring and bolt. The spring had turned to mush. I replaced the spring and it solved the problem.

Hello. I am just starting the tender for my 3.1/2 " gauge County Carlow. I am using the Don Young Model Engineer series for drawings. When it gets to the tender the series feels a bit rushed, like it was written in a hurry to finish. So to my question... If there is anyone who has built this loco or has "proper plans" that can tell me the dimensions of the tender soleplate please. I just cant work it out from the ME series. Thank you in advance. John

Thanks Bodrage, Brian and Chris. I do have a vacuum cleaner in the garage. Perhaps a bent suction pipe plus a pricker might do the job.. I'll have a go and a good run at the weekend and report back.
