    I have tried a site search, an advanced search and a google search; I am trying to find the post Geezer (I think) suggested using a threaded bolt insert to strengthen the construction of a roller-nut.  He suggested a threaded insert with a slot cut in but I can't remember if it was a bolt with head cut off, ground down or ground off - the angle my bolt is going through the nut at means the head of the bolt is protruding at an angle and also, I have used an allen bolt and am not keen on the dimple in the head, so was going to grind it all off flush but just wanted to check this was an OK approach

    Geezer here, concerning nut making.  I make the sear-plug from threaded rod... allthread comes in two types, mild steel and stainless.  The stainless is harder to work and lasts longer, but given the inevitable wear between the distal end of the trigger and the sear, I'd rather rework the sear than the trigger, so I usually make the sear out of the mild steel.  I slot one end of a bit of allthread, then cut away a bit on one side.  That's where the trigger will engage.  Then I drill a slightly under-diameter passage thru the nut, from top to bottom.  Ideally this should come out between the lugs on the top of the nut, and slightly behind the bottom/center.  (a quarter inch or so) I tap/thread the passage to take the allthread, then screw it in from the bottom.  Trim it flush both at top and bottom, then cut a nice rectangular keyway at the bottom for the trigger to engage the forward (distal) end of the tickler/trigger. Make sure the bottom end of the sear doesn't protrude into the socket, or your lock will hang up. When the sear fits correctly, I usually put a bit of glue into the passage and then screw it into place.  When the glue dries, I drill the center-passage thru the middle of the nut (side to side) to fit the nussfaden cord, or center axle that keeps the roller from hopping out.  Does that make sense?   Questions?  Geezer.

    Thanks Geezer, I'd missed the bit about screwing the rod in from the bottom, this is where I am at the moment, the hole being 5mm (3/16). Any thoughts?
