Dag Evert's "American Classic"

As mentioned on the forum, heres a picture I took some time back, with natural winter daylight.
A 2100, and a 1377, both guns have been recrowned, and had their trigger parts shimmed for play,
contact surfaces stoned, and trigger springs somewhat reduced within safe limits.
The 2100 has had its barrel shimmed with tape to remove play.
Both guns give great accuracy for the money if they are given good pellets!
The combination of pellets and guns in the picture represents something close to my boyhood dreams:-)

Maximum cocking effort

Response to "" 3.14(R squared)x Valve Pressure.""""

is not that easily computed by simply determining the MA of the lever itself. There is something to say for the scissor linkage itself. Where maximum force on the handle/lever to cock the pump occurs not when the handle closes but many degrees beforehand. So I think to compute the moment of arc where the pump handle requires the most human effort requires serious math.
