Hi there, I am new to this so forgive if needed. I am restoring an old blow torch, well 2 in to 1 and mostly going well, I have it burning now, but I have a leak coming from the pump nut area. There is no washer there but I don't think there should be? Someone I know said, just from a video I sent them, that the safety valve isn't working? The pressure release valve certainly works. Please advise, I am trying to sort this as a gift to my son as he wants to get a new canal boat with a Bolinder engine and a blow torch is how you get them started . Thank in advance for any suggestions offered.

Ah, thanks, that makes sense. So I need a new washer bit in there? What would I make this from please or can I acquire one from somewhere?

Give Base-Camp a call or e-mail, to see if they can help.

Is there a small one-way valve at the base of the pump tube?

Yes, the little pip, I think this may be perished

Base Camp was my thought too, having overhauled a 'Vapalux' paraffin-vapour lamp with parts from them.

A copy of the instructions too, vital as these lamps are operated in a way very different from most equivalents.

Go on then it looks just like a Tilley lamp, tell us more

The ….

"Lamp, High Pressure Paraffin No.1 (Vapalux – W.O. Cat. No. JA 5557),

Lamp, Store, Type B Complete, A.M. Stores ref. No. 21C/2503" ,

as the instruction-card says it is, so now we know,…..

…. is still a pressure-lamp and it is lit and extinguished in a fairly similar way to a Tilley Lamp, with a meths cup for pre-heating. Its trap for the unwary accustomed to Tilley Lamps, is a finger-attracting control that operates what looks like a flame-regulating needle-valve in the jet.

It is not. The needle is an internal jet-cleaner and should be used only as in the instructions, including never for extinguishing the lamp.

They were made, by the way, by Willis & Bates Ltd, in Halifax.

Interesting, thanks. I have paraffin lamps but not a Tilley, and have watched videos on operating etc, so hopefully won't get my fingers burnt in a figurative or real way.

If you are seeking advice or parts in England, you will need to be clear whether your device is a blow-lamp – intended to provide heat (which has been overtaken by eg a propane torch), or a Tilley lamp (intended to provide light). They work on the same sorts of fuel, and in very similar ways. A piston pump pressurises the fuel tank, and the heat of the flame assists with vapourising it. The term 'blow-torch' is (in my experience) applied to more modern heat devices, usually with butane or propane gas in a separate tank, and no need to pump. And I admit that a blow-lamp should – from its name – be for lighting. But no. English is like that. Just don't get me going on carbon brushes …

Cheers, Tim

Tim,

A quote: "Who but the English would write 'FIRE' on a bucket and then fill it with water?"

Best regards,

Well, if they didn't put water in the bucket labelled 'FIRE' it might be awkward if things go wrong around the Blow-lamp that is a lamp not for lighting, except for lighting.

Three Huzzahs for eccentricity!

(Well, it makes valves work…)
