righto, some more work today.
got the whole action apart (and back together again !)
improved my measuring setup a bit, with the stock reset spring I am getting 5 lb consistently.
changing the reset spring takes off 12 oz
bending the sear spring (more closed) takes of around 1/2 lb
then cut a coil off the hammer spring, maybe 2-4 oz off, difficult to gauge.
honed the sear, also 2-4 oz, only took a very small amount off... nice crisp break
got some M3x5 grub screws, and also found my M3 taps. pretty much done with lightening for now, next job is the initial take-up
can someone pls try to explain in fairly simple terms why shortening the hammer spring reduced the trigger pull ? i get the part about the sear spring ,that makes sense to me, but my understanding is that the hammer spring provides energy for the hammer to move forward and then strike the firing pin. it only comes into effect after the sear disengages, so can't quite get why shortening it reduces the trigger pull, unless the extra pressure when it is compressed forces you to pull harder to disengage the sear ? on the right track here or am i completely missing something ?
