I have a 16mm bell and howell TQIII projector which has a strange problem where the film doesnt seem to be going through the gate correctly and the resulting image just appears as a "blur" as if it isnt getting held in the gate at the right time. I've also noticed on the test piece of leader i used it was chomping some of the sprocket holes.

Its almost as if the claws in the gate are not precisely timed with the sprocket holes on the other rollers thus slightly missing them, and only getting it sometimes.

I wondered what part of the projector i should be looking at to fix this problem, everything else seems to look fine

Hello James.

If you return to your original posts on Film-Tech, you will find that I have posted a downloadable Technical manual for the TQ3.
This should help you find the answer to your problem which appears to be with the intermittent claw. This is the three toothed part that moves in and out of a small slot in the picture gate.
In the manual B & H call it The Shuttle.

Hugh.
