Thanks Andrew. That's interesting.

How is the spring attached?

John B

Does anyone have any experience of putting a spring below an inverted slide valve to ensure its contact with the valve face?

Any advice on how to source a new bulb for my Vertex swan neck work light? Seller RDG can't help. It seems to me that the bulb is part of the reflector unit? Anyway I can't shift it!

Many thanks

Just to report that I have used jeweller's rouge and it worked well.

The job was to solder in the backhead bushes for the gauge frame x 2. I made a jig to hold them square from some steel strip. The resist stopped successfully these from being soldered.

Thank you Massimo and all others who contributed.

Thanks for the replies. I am just interested in sealing threads at the moment e.g.main steam pipe in to the regulator and oil pipes etc into unions/bushes.

Farmer para 287 uses Boss White but this was 1964.

What is the best sealant to use these days for screwed joints within a 5" gauge boiler when subsequent access might be "difficult".

There's an error message when I try to access the binders page on this site - are binders at the moment available for ME?

Thanks

Julian, Could I add my request to Peter Ellis?

Much appreciated!

Its a while since I started this thread but I'd be interested in the drawings too if that is at all possible.

Kind regards and best wishes of the season

Is type correction fluid, e.g. Tippex, the thing for this?

John B

Thanks Baz. Looks like there is no reasonable alternative.

In fact there is an advantage - the injector will knock off if the boiler is over filled i.e. forgotten!

I would appreciate some advice on the following.

I am constructing the boiler for my 5" gauge Claud that has a round top firebox.

I am seeking to replicate the cab fittings using Don Young's methods. This involves internal feed pipes to the injector steam valves. This follows full size practice with the pipes upending in the dome space.

However I am realising that this will be very difficult to assemble regarding the myriad of obstructions in the boiler particularly as the injector valves are quite low on the backhead. Any mistakes here will be locked in once the backhead is soldered in place.

I wonder if it would be better to collect the steam via short pipes to the top of the firebox steam space. In any case Don shows a similar feed here for the blower. If so it will be much easier to erect and test before the backhead goes into its final place.

Any views on this conundrum would be most welcome.

I have fitted 3 axes DRO to my Dore Westbury and I wouldn't be without it.

Backlash? Forget it!

Yes, this what I am using. Very impressive. As Fizzy says lasts a long time under the torch at high temp for the 424.

Regarding Blondihacks yes plenty of errors there but she admits them.

Cheers

John B

Thanks Fizzy

All going well so far, but you never know! Tubes soldered in to the firebox tube plate and firebox outer wrapper soldered to the barrel using 424 and 430.

John

Thanks Fizzy, for sharing your experience. Thanks for the invitation! I am near Reading, but if I the the chance....

John B

Thanks Noel

You are quite right about a drive fit. What if it goes in awry and how do you retrieve it without damage?

Thanks Rob

The Blondihacks viewing is compulsory particularly as she is so honest about how it went wrong.

John B

Thanks Clive. Presumably the tube plate is sealed by a fillet of solder. In any case I accept that if there was a gap it would be difficult to maintain it.

Kind regards

John B

All the references I have seen advise that a front tube plate should be driven into the boiler shell before soldering. What about the capillary gap? Do we rely on the boiler shell expanding?

John B

I have fitted xyz DRO to my Dore Westbury using bits from EMS International. As with Phil, it wasn't cheap but I can say that it has transformed the machine.

Best wishes
