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 there-fore, be Sven tbe careful handling required for any grrn or weapon capabtre of inflicting a riound, however slighL

The pistol is essentially a metal-turning lathe project, and any-one possessing such equipment in his w.orkshop will have no diffi-culty ivith the elemerrtary gunsmithing involved. The drawings give Reeessary details and dimensions; a brief study sf the see-tional sketch wi0 make clear the gunis si4ple but effective con-strtrction 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 ex-tremely careful to have your centers properly aligne{ turn slowly, and avoid over-heating of the drill lContimtcil o* page 1701
