    Here are a few fettling notes on the Gloria No. 20 Table Lamp that is in the Reference Gallery here.

    I will only show the things that needed to be repaired before this lamp was fired up.

    The burner cap

    The lamp came with this mantle tied over the burner cap.

    On taking the mantle off I found that the cast brass burner cap was seriously eroded:

    The burner cap is in two parts: the cap itself, and brass adapter to fit the 1/2" by 40tpi thread of the curved burner tube. NOTE: This style of Gloria burner also comes with a burner cap that screws straight on to the burner tube (ie no adapter).

    Note also the brass mesh that was sitting inside the damaged cap, probably as a running repair.

    I decided to cut off the damaged end of the burner cap and braze (hard solder) the end of an Austramax burner cap in its place.

    The Austramax cap end was place in a vise and coated in flux.

    The threaded remains of the Gloria cast burner cap was set on the Austramax cap and the two parts brazed together.

    With a Dremel, I recut the notch for the mantle tie.

    Not perfectly straight in every dimension, but rough enough for the bush until I raid someone's shed in Melbourne to get a replacement burner cap.

    Making a fitting on the burner cowl for a globe retaining screw


    I had some 10mm stainless steel rod that I drilled using the drill press.

    I ground the rod to the correct diameter to match the other two fittings, using a bench grinder and drill.

    I then put a brass tube sleeve in the centre and brazed it into place, leaving 4mm protruding from one end.

    The brass tube cut to size

    The protruding brass rod was then split in to three leaves with a Dremel, and the brass tube sleeve threaded to take the globe retaining screw. the three leaves were then used to hammer the fitting into place.

    The fitting was then cleaned up with a Dremel fine grinding wheel.

    The generator (vapouriser)

    When I received the lamp the generator had been soft soldered to its fitting on the fuel control system.

    There was very little thread left on the tapered end of the generator. I managed to make a few threads.
    IMG_1314.jpg

    I dismantled the generator, but on inspection of the interior, and finding the packing clean, I left it as is.

    On refitting the generator to the fuel control fitting, I found that there was a leak where the generator met the fuel line fitting, so I used this this excellent muffler and kiln repair paste on the generator thread and the mating surfaces to prevent leakage. It works extremely well, yet allows for the generator to be screwed and unscrewed without excessive use of force:

    Sailmaking needles

    ...are very good for removing old lead washers.

    Testing

    Bunsen flame.

    Burning in the mantle:

    Petromax 500 cp "test" mantle.

    With glass attached.

    The final result is a very fine table lamp.

    Lacking skills and equipment I would find such a project daunting and nigh-on impossible.

    You make it look so easy which is the skill of a true craftsman.

    Many thanks for sharing in such detail.

    Regards Jeremy

    Thanks, Jeremy.

    I like to try my hand at these things, but I have to admit there are members here with far greater skills in these areas than I.

    But my philosophy is that when these lamps and lanterns were everyday household items, they were often maintained with the best skills available locally. So “handyman” repairs are quite appropriate in my view.

    I’ve got a bit more to say on the burner cap (thanks to a fellow CPL member), but it required better photos than I can post at the moment.

    Cheers

    Tony

    Handyman or craftsman. Just a choice of words really!

    All the best. Regards Jeremy
