A Sturdy Tripod Base
HERE is a tripod base easy to make and remarkably steady for all its simplicity. Two pieces of 1" x 2" birch, 24" and 26" long are lap joined 1" from the end of the 24" piece as shown. At
the center of the joint a ¼" hole is drilled for a ¼” x 1½" brass bolt with a wing nut to permit it to be taken apart. One inch from the end of each leg a shallow hole is countersunk about Vz" deep to receive the leg points of the tripod. These holes should not be too deep or else the points will not rest securely.
On the under side of the stand, rubber bumpers are screwed to give a steady three point support. Seven inches from the wing nut a screw eye is fastened to the 24" member and a chain is attached long enough to permit the full extension of the tripod. A spring fastened to the wing nut of the tripod head screw takes up the slack of the chain and pulls the legs tightly into the countersinks. The spring selected should be strong enough to permit picking up the tripod by the legs without dropping the crosspieces or base, as the tripod is moved for a new viewpoint. Unscrewing the wing nut makes the base easy to store or carry.— Walter F. Krause, Jersey City, N. J.
