Hello - newbie member here.

Found a box of Super-8 films in the attic. Shot with a Bell & Howell T20 XL in the mid-80s. Got my hands on a Chinon 3000GL projector with which I plan to capture the film to digital.

The projector is having trouble playing forward. With a film loaded I can give the little flywheel a flick with my finger and that moves the film forward an inch or two, but then it stops again. Reverse plays fine. Maybe if I was trying to rewind the film it would also have trouble. Hmm maybe I should try that.

Rubber belt on that wheel looks good. Maybe stretched?

As yo mention t has a flywheel I assume this is a sound projector. In that case the flywheel is not involved with reverse projection, which you say is fine, so that implies that there is trouble with the flywheel maybe it needs its bearings lubricated. How long does it spin for when you flick it when the machine is not running, it should be for more than a couple of seconds that it would need to move an inch or two of film.

It pays to check those belts?

The Chinon 3000GL is a dual-gauge silent projector.

Yes...no flywheel on the Chinon 3000GL since it's a silent projector. Most likely you are referring to the fan connected to the motor turned by the main belt. A new belt should get it going forward again.

The motor is turning the belt, but the belt is evidently slipping. Can it stretch out over time and I need a new belt that will be tighter? If yes, can you recommend how or where to get a new belt?

Yes, belts will stretch with use and some can develop flat spots. Others break up with age. One of the delights of buying a "working" but untested projector off eBay is finding that the belt has turned to goo and having to clean the mess up. Many replacement belts on offer are "O" rings which you might find at your local hardware store.

Using a thread/string to roughly measuring the required belt size. Then go straight to your local hardware store. Buy a bunch of o-rings of about that measured size&plus/minus say 10%. Hopefully at least one of them should be good enough to let you get going. In total this might be cheaper to buy those "genuine" replacement belt from e-bay. [Wink]

A new 2 1/4" O-ring did the trick - thank you all for your help. This projector is working great now and I can begin transferring this material to digital format.

Glade two hear Michael! I've had a few 3000GL projectors that I have restored over the years. If running well...they do make a good choice for low cost real-time transfers. Have fun!
