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:-)

Response to investment casting ( real world term) nt

Extruding is exactly the correct term and it works ALMOST exactly like the Play Dough FunFactory. An aluminum billet approximately 6" in diameter 3' long is loaded into this big hydraulic press it is heated but not to melting... The die is inserted into the machine and it squirts out the desired shape... Investment casting usually involves making a mold, casting a positive of wax, inspecting wax positive for voids, defects, etc. And if all is good the positive is made into a mold and when the metal flows in the wax is melted out and the metal fills the void... It is also called 'lost wax' method... It is called investment casting because it is a sustantial time and effort to produce parts this way.. It is cheaper to cast a 'Bad Part' out of wax than metal.... Greg
