A pendulum supports the light on one end of a pivoted crossarm, the other end of which is forked. On a banked curve, the pendulum remains vertical, but a fixed rod between the fork tilts with the engine (diagram), swinging the light to follow the curve.

A NAVY buzz bomb named Gorgon IV has lately been darting over the Pacific on stub wings in the longest flights ever made by pilotless aircraft with ramjet engines. Time: “more than 10 minutes.” This may not sound like much of a record. But ramjets, the simplest of all engines and perhaps the best for supersonic flight, are still little beyond the Kitty Hawk stage of development (PS, Jan. ’49, p. 130).

SOME of the “newest” features of the new cars are old stuff to those who know their antiques.

Torque converters, steering-post gearshifts, overhead valves, front drive, rear-engine mounting, disk wheels, inter-axial seating, balloon tires, four-wheel brakes, coil suspension, three-abreast seating, underslung frames, the V-8 power unit, and the extensive use of aluminum in automobiles came and went decades ago, together with socalled “modern” styling.

Clamp the template for the part to be turned to the guide bar, with the template axis parallel to the ways.

Tenoning With Power Tools

Edwin M. Love
A FEW accurate saw cuts will shape a tenon on the end of any piece of wood. Which is practically the same as saying that the job is made to order for a circular saw. Given your choice of home-workshop power tools, you’ll probably take advantage of the speed and precision of a bench saw for making the tenon half of the mortise-andtenon joint.
