    When fettling the Pork Pie and the earlier X246 Guardsman there is an issue with the fount’s bushing that I believe that I have a fix for.
    The issue is with the inner bush that fits between the fount bush and the control valve. If stuck, it’s typically hard to remove without damaging it.
    Here are 2 examples of the inner bushes shown installed into their founts.

    The inner bush is quite thin, and to get it out with grips usually results in a damaged gouged inner bush. :rage:

    Although the damaged bush can be cleaned up, it will always show the marks of its inelegant removal.

    What to do?

    The pump tube from most Tilleys, in this case, from a X246B, can be used to extract the said inner bush without damage.

    By dissembling all the pump’s parts, retain the pump tube and the lock ring.

    The thread of the pump tube cap is the same thread size and pitch as the fount’s inner bush.

    The lock ring is now modified, with flats, to allow a wrench or spanner to be used as follows:

    Reinstalled the modified locking ring back on the pump tube and screw the tube into the fount’s inner bush. With a spanner, tighten the lock ring down onto the bush, effectively locking it.

    Now just screw the fount’s inner bush out with the pump tube.

    Unscrew the inner bush from the pump tube and you now have the inner bush removed without damage. :D/

    Of course, you can make this tool a little bit prettier. By cutting off the pump tube’s cap threaded section and solder sweating it to some brass bar stock you can make a custom tool on the lathe.

    This tool has been invaluable and has proved its worth.

    Thank you for looking.
    Cheers
    Pete

    Excellent solution, Pete.
    You must be a Mechanical Engineer in your days to have such ideas.

    Great Idea.

    Whats the reason for this bushing anyhow? Why not have the thread directly in the fount?

    The bushing is to allow you to adjust where the control wheel ends up on tightening. For example, you can set it ‘left handed’ or ‘right handed’.

    My personal preference is to have the black control wheel set 90° to the right from the pump (that is, 3 o’clock if the pump is at 6 o’clock). I’m right-handed, so I pump with the right hand, steadying the lantern with the left, then use my right hand to open the control cock.

    Cheers
