Hi Bruce and Joe,
With projector belts, my opinion is that too tight is probably worse for the projector than running too loose. I usually try to run my projectors belts as loose as practical but without any slippage ocurring. There's less internal friction to overcome giving good variable speed response and much less wear on the motor and shutter-shaft bearings. Running speed is effected when overtight belts are used resulting in a slower and weaker machine, struggling to get up to its correct running speed, getting hotter than usual and sometimes they will stop running after a while when the motor wiring burns out.
So I believe too loose is preferable to too tight, but the correct belt is the best belt to use.
This subject reminded me of the story about Goldilocks and the three bears. If you recall, the medium sized bed was the best size for Goldilocks. Not too big, not too small, but just right. The same basic principle can be applied to projector belts.
