Overhead Projector
He Shops! He Scores!!

Target Located:
So when a second-hand orphan overhead was spied recently for $30.00 in a Silverton photography shop, (left), it was eyed with hope. No bulb was included, but the socket looked common enough. Better still, this unit, a "3M Termo Fax Model 66," sported the refraction optics so loved from school days. $25.00 was offered and accepted. Once purchased, the unit was completely cleaned of the years of dust and crud that had accumulated throughout. The next task involved tracking down the bulb

Bulb Woes:
Unfortunately, in spite of the common-looking socket, the proper bulb was not located in town, and may indeed be extinct. But being from an age of metal construction and screw/bolt technology, the bulb system was easily removed and with some minor modifications, it seemed like an easy matter to fit it with a common socket, utilizing an easy-to-find standard bulb.

The best bulb candidate seemed to be a 150 watt quartz halogen, (right), readily available in hardware stores for use as outdoor illumination. In fact, a motion-detection weather proof version had been purchased several years back at the Goodwill. With some minor screw-twisting, it relinquished its socket, which was transplanted into the overhead's lamp assembly. Once fitted and turned on, the unit performed flawlessly, projecting a sample view graph with clarity and brightness. Better still, replacement bulbs are easily available in most hardware stores for under $5.00. We now have a working overhead projector, to join the ranks of OL5 presentation aids.
