Did he ever mention -- has anyone mentioned -- a numerical spring
constant for LG/Jardine hammer springs?

It's a heavy spring so you can't just compress it with a handy weight
and measure deflection with a rulera.  But I rigged up an arrangement
with a 65# weight at the end of a 4' lever and measured the deflection
with a dial indicator. I got 2149 lbs/in on both the installed spring
and a spare.  Another spring that came with the hammer but may not be
an actual LG product was 2016 lbs/in.
