TARGETPISTOL PNEUMATIC by Edward F. \Alsldron McLing thls pistol will be ercellent trcrining lor your metrrl lcfhe work.
rl-tHIS air plstol. is an interesting toy, yet it shsots hard enough I to break a milk bottle, and can be used for target practiee or even for kining small game at reasonable range. It must therefore, be Sven tbe careful handling required for any grrn or weapon capabtreof inflicting a riound, however slighL The pistol is essentially a metal-turning lathe project, and anyone possessing such equipment in his w.orkshop will have no difficulty ivith the elemerrtary gunsmithing involved. The drawings give Reeessary details and dimensions; a brief study sf the seetional sketch wi0 make clear the gunis si4ple but effective constrtrction and firing action. The force with which tJre pellet is ejected from the muzde depends upon the amount of air presflrre pumped into the chamber, and needless to say, entire success of the gun's operation is based on a perfecf seating of the valve. Tlre barrel is the first piece to be worked on- Bore it from d piece af.9ux3/4" piece of soft iron rsd" Stert the boring rvith an 11/64" drill When this drill is as deep as it will go, use another LLI64,'drill to which a piece of E%."drill rod has been welded. It is preferable to set the 3/+" rod in the lathe strapped against a headstock center with the other end in the center rest. Be extremely careful to have your centers properly aligne{ turn slowly, and avoid over-heating of the drill lContimtcil o* page 1701
