    Seller was local, so cash on collection, saving the postage of a bulky, weighty item and I was persuaded to add another (smaller) Tyers to the No.3 featured HERE.

    A bit of minor fettling to get it running: a jet thoroughly clogged, a new sealing washer for the pump-to-tank joint (the pump is removable) and a new viton seal for the fuel filler cap. As in the Tyers No.3, the non-return valve in the base of the pump tube relies on a sprung-loaded metal-to-metal plunger and seat seal.

    The fuel filler cap incorporates an ingenious round-based brass disc backing the fibre sealing washer. It creates a 'floating' washer to ensure a good seal and once the washer has got a grip it doesn't rotate on the sealing face as the cap is turned, preventing wear. I epoxied a viton washer to the fibre disc to create a more certain seal.

    The seller had forgotten to include a cast iron crucible and windshield/pot rest in the auction listing so those came as a pleasant surprise when I arrived to collect the furnace.

    Priming with alcohol takes about ten minutes as a quarter litre of the stuff poured in the cup in the base of the burner shroud burns off.

    Ignition of the vapourised paraffin comes with roar ...

    ... not quite as loud a roar as the No.3 though, which is bigger in all respects - wider-bore pump, bigger capacity fuel tank, larger burner, larger jet.

    Great antidote to a frosty day.

    Hello John excellent score, and as all ways brilliant documented tutorial/fettle.

    I like the design of the hinged flame spreader. Sheen the makers of the infamous flame gun, i notice is all so based in Nottingham,im sure they once produced a furnace as well

    Hi Brian, good to hear from you!

    You're right that Sheen made a furnace, it featured in THIS post.

    Looking at that example it evidently didn't have as robust a frame as the Tyers and the pump and valving wasn't as substantial.

    Hi John thank's for updating me, i thought they did.
    I see what you mean regarding the build quality between the Sheen and the Tyers, but i would think looking at both designs the Sheen was probebly made in the late 50's early 60's. Where the Tyers with its ornate style and build quality i would put it to be from the 30's possibly earlier

    Another monster flame machine! :thumbup::thumbup::thumbup:.

    (I've been a little bit restricted in my fettling pursuits lately, having to work almost full time for the last few months, but I will have finished my Bering Flame machine sometime today if all goes well.)

    Cheers

    Big old beasts, and apparently quite solid. Interesting that they have been retained so long.

    That loop in between the burner an the tank, is intended to be used as a handle or does it have some other purpose?

    Solely as a handle Jim. It's at the balance point (more or less, depending on the amount of fuel in the tank) and makes it convenient to carry from van to on-site job.

    Some years ago I was at David's and we had a successful fettle.
