I've got 3 E-7 machines now with all the same problems: broken sight glasses in the G-55 one shot oil reservoir (oil pump unit) allowing all the oil to leak out. I'm having a tough time finding any new ones. Seems that Wolk and Lavezzi no longer make these parts. Has anyone had any luck with having local glass shops make these? I tried a local shop about a year ago and their glass was either too thin or too thick to fit in the pump.My E-7's still have rock steady pictures. Am I going to have to learn the fine art of glass cutting???

Yup!I made some windows for a Super movement out of a Windex bottle for a drive-in theatre in South Dakota once. They lasted the entire season.
Josh had a leaky one, also. But I don't remember what he did to fix it.

Ken,
Why don't you cut them or have someone cut them out of a good clear plastic. You should be able to seal that OK. Plan B find some junker E-7's cheap.

You might want to look in a hardware store for some Lexan. It's strong and clear, we use it in aircraft windshields.

Hello, Ken,What is the thickness of the glass you are in need of?
I am sure we can find the material you need as there is glass in thickness from microscope slide cover glass to 1/4" thick plate glass.
The Broadway Theatre in Mt Pleasant Michigan has 2 E7's they have no use for. Sam Staples is the President of that group. SWS333@chartermi.net
Hope that will help you.

The ones on the E7s I have are .090" thick plastic with the words "Full" and "Refill" hot stamped in. Home Depot Lexan storm window material is .095" thick. Should work fine with oil. I found the right size Gaskets and O-rings in the plumbing department at Sears, so most plumbing suppliers should have them.

Pete:Mine are all plastic and all have the "full" and "Refill" markings. I never thought about Sears stores for the gaskets. Good idea, never even thought about using Lexan. Maybe I should check the local glass companies and have them cut these in Lexan. That should stand up to the oil and temperature extremes we have at the Skyline drive-in.

Any thick clear plastic packaging labeled "PETE" (recycle number "1") or polyethylene Terephthalate should be unaffected by oil. (It's the same plastic that polyester film is made of):

"Plan B find some junker E-7's cheap"
These were my favourite projectors of the Simplex clan. I hate the thought that some of them have been neglected to the point where they could now be considered as "junkers".

Rick, E-7's are also one of my favorite projectors. One of the most stable picture I have seen. You either loved or hated them. Ran lots of film through them and still support two home booths with E-7's running. Sometimes we do find a few of them in such sad state that all one can do is strip them and save the parts to keep others running. That is becomming more common these days.
Ken, I don't think the heat of your DI will bother a good plastic. As long as it handles oil and is sealed properly you should have no problems.

Dick:
What happens at the Skyline is during the summer the sun shines directly into the big picture windows of the booth directly onto the oil pump sight plastics for at least 8 hours a day. I think the ultraviolet rays are disintegrating the plastic. Bob McRae replaced the one sight glass plastic on our main projector only 4 years ago and it has now turned brown and cracked. Naturally all the oil leaked out.

Ken,
There are these funny things called window shades.........might they help your melting plastic situation?
We have a pile of old E-7's at CLACO. If anyone needs a part just give us a call and I'll see if its on the machine and let you know what shape it is in. We also ahve a ton of NOS Simplex parts.

Ken I hope you put a glass sight glass back in my E 7 that you have. Nothing but the best!
