Canteen From Two Pie Plates: Rims Soldered Together, a Screw-Cap Neck in the Edge (Boy Mechanic, 1919)

A canteen "for the camper or hiker", sent to The Boy Mechanic (1919) by J. R. Townsend of Itasca, Texas: two nickel-plated pie plates soldered rim to rim, the screw-capped neck of a metal-polish can soldered over an opening in the edge, and two wire loops for the snap hooks of a shoulder strap. The book gives no sizes: the plates set the size.

Instructions

1

Read The Boy Mechanic

"Two good-quality pie plates were soldered at their edges to form a water-tight container." (J. R. Townsend, Itasca, Texas.)
2

Solder the plates together

Take two good-quality nickel-plated pie plates of the same size. Clean the rims, set them face to face, and solder them together all round the edge so the joint is water-tight. Use lead-free solder: this holds drinking water (our choice; the book only says solder).

Cut the neck off the can

Take a small metal-polish can with a screw cap. As the book's drawing shows, cut off its sloping top with the threaded neck, and trim the cut edge.

History and honest limits

From **The Boy Mechanic, Book 3**, edited by H. H. Windsor, Popular Mechanics, Chicago, 1919 (Project Gutenberg 71856), "How to Make a Canteen", sent in by J. R. Townsend of Itasca, Texas. The book gives no sizes and names no tools; the lead-free solder, the tools, the strap material and the leak test are ours.
