    Hi stovies I can't remember if this has been posted before if so my apologies.
    Here is a good way to use any old enlarged jet/nipples if you seal up the enlarged orifice the old jet can be used to give a fantastic pressure test to any newly fettled/restored standard 1 pint and beyond stove blowlamp.

    Here in the above pics I have sealed the orifice to the two jets, the small standard stove size I have sweated a piece of brass sheet over the orifice, the second I have just covered the orifice with a blob of solder.
    When a stove has been fettled/restored, the blank jet can be screwed in place, and the stove can then be pumped up to a very good pressure, and then either immersed in water or have soap foam brushed over the stove to check for leaks, this is easier than placing a finger over the jet and is better.
    Using this system the whole stove, and the complete burner assembly can be checked for leaks, there is nothing worse and fettling a stove and putting it back together, and finding a leak in the vapouriser tube which has happened to me on a one pint Veritas, this way the stove can have a full pressure test, prior to polishing it and firing it up, this is my way now I pressure test all stove and blowlamps.

    Hey Brian, simple yet effective idea to pressure test some stoves.

    Hi Ron it really is effective as you can really put a good amount of air in the tank that would let you show if there was a very slight leak which is good if the tank has stress cracks, and it puts a worn jet in to good use.
