Anybody know how to remove a lamp/bulb from a Kodascope Eight-33

It lit for about 6 times I was experimenting but now it tries but won't. I suspect corrosion and tried to remove it to clean off the bottom, but 1/ I don't know which way to turn it, and, 2/ appears the metal receptacle base is also corroded around the lamp base

This is from memory but try gently pushing down and turn about a quarter turn to the left.....

Be very careful! If it breaks it will really cut up your hand! [Eek!]

Thanks Bill, I tried easy-down-push-turn, but, as stated looks like the metal bottom of the lamp and the metal socket it goes into have corroded together so the lamp won't move.

As Paul said - be vary careful or the lamp will break, so I didn't dare try any more force.

But I guess I don't have any choice now but to try harder, using some kind of protection against broken glass.

I do have two more lamps in case I break the original.

Thanks to both of you, Bill and Paul, for replying to my original posting.

Steve, try using a spray like CRC electric contact cleaner around the base. It may free it up and doesn't leave any residue...

See if you can locate an electrical detox/ lubricating spray on-line. Squirting that in and around the socket and base may help if it is corroded in. Once
Lamp is out, wipe off any lube residue in or on the socket. It won't harm the electical components but may not tolerate heat from the lamp.

Moderators, please delete this double post. Don't know how this happened.

Joe and Barry, thanks for the suggestions to spray. [Smile]

I sprayed all around quite liberally with "Electronics Contacts Cleaner with Silicone" waited a few minutes and that did the trick. I was able to hand remove the lamp, file off the corrosion from the bottom of the lamp, and emery paper off the corrosion on the projector contact.

Put the lamp back in and it works like a charm.

I recently had this 1930s projector 'donated' to me along with a bunch of other cameras and projectors by a customer lady who's father recently passed away in Niagara Falls Canada, he had bought it and a 1930s Cine-Kodak Eight-25 movie camera back in the 1940s. Then he later bought a couple of those 1950s brownie movie cameras, and later a couple more cameras and projectors.

Holy doodle, this Eight-33 projector and the Eight-25 camera are in immaculate condition, still working after almost 80 years ! they are real beauts

I'm planning to use them at a local festival exhibit in September to show young kids how things used to be done and spread the word about my youtube channel of old historical homemovie and professional films of Canada.

So, thanks for the suggestions everybody to get the lamp working again.
[Smile]

Glad to hear the projector is up and running! That is very cool that you are going to show off the equipment to the youngsters. The cameras and projectors from years ago are very well built and I'm sure the kids will be impressed. [Smile]

Thanks Bill,

Yes, eh, imagine being able to buy anything these days that would still be working 80 years from now.

And betcha at least one kid will ask me - "where's the sound ?"

hahaha LOL
