Author Topic: Apartmentizing a Brenkert BX-80 Projector Gerard S. Cohen Jedi Master Film Handler Posts: 975 From: Forest Hills, NY, USA Registered: Sep 2001 posted 04-19-2003 03:20 PM                     [Robert Sprague, (Historian and Formerly With the Brenkert Light Projection Company) sent me the following letter and photos which I post because he cannot connect to Film-tech, having neither telephone line nor computer cable in his new, tiny apartment in Senior housing in the center of Petoskey, Michigan:] I've finished constructing (base, wiring, etc., my "Mini-Brenkert" Apartment Projector, several photos enclosed. But please excuse the extreme distortion due to elevation of camera and its severe wide-angle lens! (It was one of those cardboard throw-away cameras.) But you'll get the idea of what I did!!! Components are: Brenkert BX-80 Head Brenkert C-7 Incandescent "Spot Lamp" Lamphouse (Smallest model Lamp "B" ever made, c. 1922) RCA Mini-1090B Soundhead with Non-RCA Flywheel 18" Chicago Cinema Upper Magazine 16" Simplex Lower Magazine (countersunk to fit into base) Base designed and built my ME Eventually I'll have to modify the lamp to take a quartz halogen bulb as proper bulbs no longer avail. I await an amplifier and speaker (from Paul Pottash,) otherwise the projector & soundhead are wired and working. On the backside of the base I have a DC exciter power supply. A footplate on casters of base looks weird in these distorted pics, as it's triangular! Best wishes to all Film-tech guys and gals, especially Brenkert fans!

Hopefully he'll be able to get more pics, and closeups, that can be sent to the Picture Warehouse. That baby lamphouse it pretty cute too.

I have been assisiting him with sound hook-up info and a DC supply for his exciter lamp. Sure wish he had email capability, but it's fun corresponding with him via snail-mail, nonetheless.  |  IP: Logged Ken Layton Phenomenal Film Handler Posts: 1452 From: Olympia, Wash.

Cohen Jedi Master Film Handler Posts: 975 From: Forest Hills, NY, USA Registered: Sep 2001 posted 04-29-2003 05:05 PM                     Robert Sprague thanks the above posters for their comments, and desperately seeks some small parts which I have posted for him on the Equipment forum under the thread "WTB: BX-80 Parts for Apartment Projector." If you have spare Brenkert parts, please check it out. I've summarized the never-ending Film-tech discussions about the best oil to lubricate Brenkerts, and Robert replies: "The 'oil' I use in my Brenkert is 'Mobil 1' 5W-30 Synthetic Oil: It is great and leaves a sheen on all parts for 'starting-up,' yet is very light and does not 'gum up' and does NOT bother the beautiful maroon finish inside the gear compartment. It is EXPENSIVE for a motor oil ($5 per quart at Wall-mart) but CHEAPER than what dealers sell as 'Brenkert Oil.' NEWS: No one today makes an oil just like the original Brenkert Projector Oil!

I use ISO 10 spindle oil, available for around 5 buck a gallon. Josh  |  IP: Logged Paul G. Thompson The Weenie Man Posts: 4718 From: Mount Vernon WA USA Registered: Nov 2000 posted 04-29-2003 06:10 PM                     The ISO 10 Josh speaks of is supposedly a direct replacement for the orginal Brenkert Oil. In the days of Brenkert, I think it was either Mobil, Conoco or Shell Oil company that made it. It has been a while, but there was a thread that discussed Brenkert Oil. After several investigations, I found out that ISO 10 was what supposedly was used.  |  IP: Logged Mark Gulbrandsen Resident Trollmaster Posts: 16657 From: Music City Registered: Jun 99 posted 04-29-2003 06:22 PM                     Actually the Mobil 1 is a very good oil to use in a Brenkert as long as you stay with the lighter oil. A synthetic oil is far more desirable over any other oil sold for projection use. I can definately speak from experience on this one. Present day Simplex oil is nothing more than pure Mineral oil at 5W. Mark @ CLACO P.S. I run Mobil 1, 10 W 50 in my car and recently it most likely saved it from seizing up when my head gasket blew!! This is according to the machine shop that rebuilt it. Had it had regular old oil it woulda been burnt really bad.  |  IP: Logged Paul G.

It'll burn up the crankpin bearings.  |  IP: Logged Mark Gulbrandsen Resident Trollmaster Posts: 16657 From: Music City Registered: Jun 99 posted 04-29-2003 08:30 PM                     Am running Golden Spectro Synthetic in my HOG, have been since I owned it. Still runs like new. Mark  |  IP: Logged Paul G.

I had good luck running a mixture of Hog Oil and Skunk Piss (STP) in mine....  |  IP: Logged Mark Gulbrandsen Resident Trollmaster Posts: 16657 From: Music City Registered: Jun 99 posted 04-29-2003 10:55 PM                     Golden Spectro is siold by many Harley dealers. Its a very high quality designed for motorcycles type oil. I'll have to go out to the garage and see for sure what weight it is, but I wasnt to say 10/50. Its not cheap stuff but nothing good is cheap. I buy it in the half gallon container for convenience.
