    Has anyone tried this?
    It seems so much more secure than a press fit, though of course if it ain't broke no need to fix it...
    Only issue I can think of is to keep it cool when heat treating the spring.
    If the hole came out over sized (which I'm sure has never happened to me or anyone else! :) ) it might be a sensible approach.

    If you use stainless that might work, but even then getting it to sit at a proper height will require a hole to sit it in. If you use titanium, you cannot solder to it. Frank

    Yeah, I was working on a prototype and somehow the wrong drill bit got into the slot for the 53 bit...dang shop elves not paying attention.
    It's sticking up higher than I'd like, but I have to relieve the handle scale anyway so not a huge deal.
    Seems to be working, time will tell- perhaps someone will comment who's been able to test it over time?
    Thanks, Frank!

    Right now titanium is on my "someday" list- got my hands full making simpler folders, and for me simple means all stainless.

    Why do you have to relieve the handle scale?

    Just put a flat on the ball...

    i think it was more albot the ball beig a bit more prowd then the thickness of the pivot washer (causeing binding when being closed or opened cause of the lock moving into the scales ) my best way to gauge the ball depth to the folder blade was to use another of the same washer to act as a press stop when pressig theball in

    if you mistake the press fit you could try a larger ball

    I press in balls using an .018 shim to gauge depth, and .020 washers.
    This stops 90% of any binding issues.
    The other 10% get a couple of strokes with a diamond file to put a small flat on the ball, giving me the extra room I need.

    Oddly enough, a properly placed flat actually decreases drag too.
    Doesn't seem like it should, but it does.
