    Hi fellas, ive been inventive with a bar of soap.
    A Collins Brother Radiant Star i have had a pricker issue, i did not know at first but it didn't seem to clear the jet , so under investigating the pricker lever worked but the needle did not go up and down. A closer look, there was no ecentric block it was gone no block bits nothing but the pin. 20191121_111718.jpg
    What to do, i have sat on this for a while. Thinking, ill have to be resourseful. I looked at other brand lanterns ecentric blocks for ideas.
    Action time.
    I cut the block of an Austramax filed it down to close size i needed with my dremel and small files. 20200204_142638.jpg
    Cleaned it up a bit.
    I set about using a small hand drill and drilled a hole the size of the pin diameter,

    Its looking good, taking shape my plan is coming together.

    I silver soldered the two bits together.
    Look a bit rough but its solid.

    I set about cleaning and filing to shape and clearance to fit into the lever gap.

    It has come together better than i expected,

    Well done @Darryl Durdin you have an engineer inside of you.
    This is a sample of the obstacles to be overcome. With your native ingenuity the victory will be all the sweeter.
    Looking forward to the money shot.
    Cheers
    Pete

    I had a similar issue on an Enders stove. The eccentric 'pin' that moved the pricker block up and down had sheered off so I drilled a hole the correct size (approx 1.5 - 2mm) where the stub was left and force forced a tiny steel 9BA or 10BA screw into it before cutting off the excess. It didn't look pretty but the chances of finding a replacement Enders part was pretty much zero!

    @Darryl Durdin
    Nice work. very much the original.

    My approach would have been simpler.
    Do z shape bent in the lever shaft. Making it turn eccentric.
    Use the end of shaft as pin.
    Thats it.

    R55 generator lever works pretty much the same.
    Regards
    Willi
