I recently started my projector with film in, it ran properly for about 30 seconds and then stopped just showing a single frame.Checked belts, cogs etc..all OK? I don't know too much about the workings of the projector. Can anyone advise? [Confused]

What happens if you run it again without film? Do the sprockets turn? Does the spindle on the rear take up arm turn?

Posted by Alex Morrison (Member # 5440) on June 18, 2016, 10:29 PM:

Thanks for the interest. The sprockets do not turn without the reels fitted. I'm not sure about the arm thing?? Well, the spindle started to turn but stopped after 2 -3 seconds. I also don't have a manual or any information on the Eumig.

This projector has provision for quarter inch tape to run in synchronism with the film. It is on the rear of the projector and the movement of the tape controls the speed of film projection via a pulley on a sliding arm which is linked to a rheostat.

It may be stuck in the wrong position as when all laced with film and threaded with tape the sliding arm is kept at one end by the pause control of the tape recorder. This supplies no power to the projector.

When the tape pause is released the sliding arm moves and the projector starts. The tape then keeps the projector in relative sync.

This is a possibility, although I cannot be completely sure of the fault.

The P8 Imperial is now over 50 years old and may need some attention.

Thanks Maurice, is the provision for the tape accessed when the side of the projector is dropped, or is it somewhere else? The motor seems to run and the lamp is on but no movement on the sprockets or spindle. Remember I'm a complete novice at this and you have to really spell it out for me.

Posted by Barry Fritz (Member # 1865) on June 19, 2016, 08:57 PM:

Short of the issue Maurice mentioned, you need to pull the back off and check for belts slipping or broken.

Posted by Maurice Leakey (Member # 916) on June 20, 2016, 02:55 AM:

I assumed you had already opened the back? If not, loosen the knurled screw on the top of the projector and hinge down the back.

However, you say that the motor runs and the lamp lights. These indicate that it is not the "swinging arm" which I described. This shuts down the power completely.

As Barry says, it is probably the belt problem, it may look alright but is not gripping. These belts always had a short life.

OK. got the sprockets turning with film on, now it seems to be running through the gate and slowing it down doesn't help, but it's an improvement from where I was before. [Razz]

The films I'm trying to show are our wedding 50 years ago, so it would be great if I get them going.

Posted by Maurice Leakey (Member # 916) on June 20, 2016, 06:34 AM:

It seems you're getting there!
I suggest you run with lamp, no film, for a reasonable amount of time in order to warm everything up, including all oils and grease.

Posted by Alex Morrison (Member # 5440) on June 20, 2016, 07:46 PM:

Thanks Maurice, ran it all as you suggested and it was going well and then the main belt broke, so do I have to have the proper belt ?

Posted by Maurice Leakey (Member # 916) on June 21, 2016, 02:25 AM:

Obviously the correct belt is the one to use, but anything that fits would do.
In the fifties I used the rubber rings that secured the lids on the Kilner glass preservation jars. They were so much cheaper than the proper belts and lasted just as long!

Posted by Alex Morrison (Member # 5440) on June 21, 2016, 08:04 AM:

Good one Maurice, I'll try some other ones I have.

Thanks again.

Posted by Alex Morrison (Member # 5440) on June 22, 2016, 04:11 AM:

Got a new belt, got it all going again and now the film just runs through the gate. The film seems to be in the cogs OK but just runs through??

Posted by Maurice Leakey (Member # 916) on June 22, 2016, 05:21 AM:

Have you closed the gate?

Posted by Brian Fretwell (Member # 4302) on June 22, 2016, 07:42 AM:

Did the P8 Imperial have tape sound as well? I only remember the P8 Phono and Phono Novo

Posted by Maurice Leakey (Member # 916) on June 22, 2016, 09:04 AM:

Yes. I once had one.

Posted by Alex Morrison (Member # 5440) on June 22, 2016, 08:30 PM:

Yes, closed the gate but the film just runs through and goes through the bottom sprocket without the loop. The P8 Imperial I have does not have any sound. [Confused]

Posted by Maurice Leakey (Member # 916) on June 23, 2016, 02:33 AM:

It sounds that the claw is faulty or may even be broken.

Posted by Alex Morrison (Member # 5440) on June 23, 2016, 06:39 PM:

What and where is the claw??

Posted by Maurice Leakey (Member # 916) on June 24, 2016, 02:19 AM:

The claw is a small tooth shaped item which has an intermittent in-out movement which stops and starts. It pulls down the film in the gate, pauses for projection, and then as the shutter obscures the light, it then pulls down the film to the next frame.

All movement achieved at least sixteen times per second!

Posted by Alex Morrison (Member # 5440) on June 24, 2016, 03:07 AM:

Thanks Maurice, I don't think there is one on my projector. Could've got broken over the years. However, there's a chap who lives quite near me who believes he might be able to help, so I see him early next week. I'll keep you posted.
