    Has anyone found a source of latches as used in Middleton or Excalibur triggers?
    I haven’t found any on the net yet.  With a somewhat limited metal working shop, I was thinking a good way to make one might be to start with a large hex nut:

    That would work. I'd drill the pivot hole first, using the flats of the nut to clamp it in the vice. Next I'd round off edges using a file or belt sander. Then a dremel or hacksaw to remove the excess material on the bottom of your image, finally using a nice sharp file to shape the shoulders. Use a machinist's file that has a smooth edge so as to only file what you need off. Should take about a half hour to an hour.

    Hard to tell what kind of steel you're getting. Remember the graded steel nuts (grade 8 and etc) are only hardness, not alloy. McMaster says it is alloy steel, my guess is 1018 so it'd work.
    Hmmm, I should start offering to make little parts like these for trade.  Smile

    Hotspur, that's a great idea. I've avoided making a full-powered bow with a modern style release mech  for a long time because I couldn't figure out a cheap and easy way to make that type of catch out of steel with my limited metalworking capability. I've made a few from Delrin for pistol-size projects, but was concerned that material might flex too much or even break under stronger loads. I'll have to pick up some big hex nuts next time I'm in the hardware store and try it out.

    Thanks for the input guys.

    I have guestimated the dims of a latch below based on some dubious web info.  Can anyone with a latch and some callipers confirm?
