    A well-used example, seals, pump cup washer and NRV ‘pip’ replaced, so functional and not pretty.

    No priming cup when I got the Bialaddin a couple of years ago so I made one, very loosely based on that on a Mk.I bowl fire, with a priming ‘spout’ (actually more of a chute) to conveniently channel priming alcohol into the cup.

    Brass sheet was from a badly stress-cracked fuel tank from a stove I canibalised for parts to make up a good example. Hard soldered (silbraze) construction to cope with the heat of priming.

    Before trimming and clean-up.

    The spike on the base engages with a hole in the reflector, orientating the filling spout to a point between the guard wires and preventing the cup from twisting round when filling.

    @David Shouksmith helpfully pointed out that though the priming cup with a spout equipped only the Mk.I bowl fire, the later models still had that locating hole in the reflector.

    Sure enough, there it is.

    Cup installed, spike/pip engaged.

    On the Mk.I, two guard wires straddle the vertical centre-line. On this later version a guard wire occupies that centre-line.

    Consequently, I’d to ensure the spout/chute was offset when the spike/pip was engaged with the locating hole in the reflector.

    Excellent! Great work on the priming cup, filler chute, and engaging spike.:thumbup::thumbup::thumbup:.

    I’ll have to see what’s on my unfettled Bialaddin bowlfire.

    Cheers

    nice work on the cup, I always wondered what the hole in the reflector was for on my bowl fire.

    Ahhhh now I see, mine must have a later heater. Thought it was a rogue reflector that escaped quality control when it came out of the factory.

    @presscall Excellent job on the priming cup! Good to see the heater fired up. Been looking for a Bowlfire for a while to add to the collection....

    Great looking heater. Love the design of the wire guard.

    And that's some mighty nice brass-smithing on the preheat cup!

    Mike.

    The homemade parts work well.
    The design is nice and stylish.

    How warm is this type of heater actually?
    Will it warm a private room in winter?

    They do work well. I am not sure of the Kw output but it is at least 1Kw maybe more. But you do need ventilation is using indoors so you lose some heat to the outside air.

    @Camp numao
    Fireexit’s made a vital point about ventilation and that the resulting draughts reduce the effectiveness of the heater in warming the room.

    I recall from my youth that a heater of that type wouldn’t be expected to make the whole room snug, but would provide localised heat that people would cluster around. Modern levels of home insulation would introduce a risk of exposure to carbon monoxide.

    The condition of the reflecting surface makes a big difference to output of course.

    I’ve used the Bialaddin to best effect in camp in the open, where it provides a welcome focal point for friends to gather round, some getting more of its heat than others (!) but all benefitting from the visual effect of a fire at least.

    @Fireexit1 @presscall

    Thank you for letting me know.

    You're right, like other combustion stoves, you need to ventilate it constantly.

    As everyone says, I think it would be perfect for warming my feet when it's cold outside.

    I haven't gotten one yet, but I'd like to get one and try it out if I get the chance.

    Thank you.
