Due to AC, the rods have to be the same size since current is "alternating" between the two rods and not in the straight path as with DC. Just that DC usage along with high amperage really punched the light out.  |  IP: Logged Louis Bornwasser Film God Posts: 4441 From: prospect ky usa Registered: Mar 2005 posted 08-13-2014 07:03 AM                        Regarding work ethic and projector cost. Equipment was very expensive back in the 1930s compared to now if adjusted for inflation. If they had "kept up" an XL plus soun dhead would have gone for 30K+ instead of 10k+.  |  IP: Logged Gordon McLeod Film God Posts: 9532 From: Toronto Ontario Canada Registered: Jun 99 posted 08-13-2014 10:05 AM                     That was a C70 not a C7 it was the replacement for the Ashcraft type D It was rated for up to 70amps and was a little more efficient reflector than the Peerless one or the Enarcs  |  IP: Logged Will Kutler Phenomenal Film Handler Posts: 1506 From: Tucson, AZ, USA Registered: Feb 2001 posted 08-17-2014 09:57 AM                     I am currently restoring 4 E-7s that I'll probably keep as trailer queens. I was lucky to come into a stash of new E-7 parts and have enough to build 4 machines (2 obliques and 2 verticals). If I want to use them, I'll probably swap new parts out for old. The biggest pain has been paint. I have been unable to get a powder coater or custom rod shop to refinish for me. A few F.T. members recommended Premium Décor black appliance epoxy...excellent stuff and matches original black, perfectly! If you spend the time to rub it out, it will replicate the early gloss finish perfectly. A real pain is white, as most whites today will yellow/brown with exposure to heat and chemicals. I am now experimenting with high temp auto engine enamels, which I previously had difficulty with. The only parts that I have not located is the 1265 upper film shoe that tripped the fire shutter when film breakage occurred. E-7 and X-L have different part numbers and I suspect the geometries to be different. For those of you with worn gate parts and upper film shoe, there is the possibility of hard plating and regrinding..... Not sure who manufactured the parts, but either Wolk or LaVezzi did manufacture (or experiment with) Nylon and Delrin gears. Good idea, as Delrin is a self-lubricating material.  |  IP: Logged Steve Matz Jedi Master Film Handler Posts: 672 From: Billings, Montana, USA Registered: Sep 2003 posted 08-17-2014 11:25 AM                     Will; Why not do the Powder Coating Treatment yourself. Companies like EASTWOOD have the Kits and Colors. You go buy an old Electric Stove/oven from GOODWILL,SALVATION ARMY,ETC. Don't use your Wife's Stove or she will divorce you. Most powder coats bake at 350 to 400 degrees F, My brother just recently restored an old NORTON COMMANDO and powdecoated many of the Chassis parts. It looks better than when it was OEM. I Think he got the Oven he used for Free from ST.

My problem is I live in a medium-sized apartment, so I need to be careful and am limited on work-space. Powder coating these parts takes a lot of work due to outgassing problems with both die-castings and iron sand-castings. Essentially, the parts need to be masked and media stripped. Masking is then removed, and the parts baked overnight to burn off entrapped oil, etc. Once complete, the parts are then washed with phosphoric acid metal prep. Parts are re-masked with high-temp powder coating tape. Parts are then heated for several hours to around 400-600 degrees for out-gassing, then powder coated and baked. Once complete, there is still no guarantee against out-gassing problems. If there are any, then the parts need to be stripped and the entire process repeated. Jim, I love collecting these old projector advertisements. I have never seen the two you have posted, and am interesting in obtaining the first. I have the E-7 orange, black and white wartime advertisement that I had professionally framed.  |  IP: Logged Steve Matz Jedi Master Film Handler Posts: 672 From: Billings, Montana, USA Registered: Sep 2003 posted 08-17-2014 04:03 PM                     I love old vintage advertising and just like today "TRUTH IN ADVERTISING" still walks a Fine line. In 1939 Every Projector Mfg made the Finest Projector in the World;If you don't believe it just ask them...LOL! 1939 CENTURY P......FINEST PROJECTOR IN THE WORLD! 1939 BENKERT BX-80..FINEST PROJECTOR IN THE WORLD! 1939 MOTIOGRAPH.....FINEST PROJECTOR IN THE WORLD! 1939 DEVRY..........FINEST PROJECTOR IN THE WORLD! BTW: Interesting history from "ROBERT SPRAGUE" long time BRENKERT Employee.. He says MOTIOGRAPH in the 1930's was in a deal to MFG Projector Heads for BRENKERT but the deal fell through around 1937. BRENKERT than rush designed the BX-80 in May 1939...The Oil Spray Lubrication System on the SIMPLEX XL is basically a Copy of BRENKERT'S 1939 BX-80 Oil System design.XL's weren't around til 1948 and in service til 1949... Now it's unheard of that any Projector Mfger would ever Copy features from another Mfger Also up until 1939 when CENTURY Designed the P(which is their own design} almost every Mfger was basically Cloning the "SIMPLEX STANDARD"(E7aside) In fact everyone's parts interchanged. Century changed the Framing Design that was used by almost everyone up til then by rotating the intermittent while the Projector is running to a Rack & Pinion Style that moved the intermittent in an up and down motion which IMHO is a better idea. Also Century's idea of separating the intermittent Sprocket Shoes from the Film Gate was a good innovation. Even though it required 2 Actions it permitted Adjustable tension to be applied to the Intermittent Sprocket & Picture Aperature separate and independently. These 2 innovative Features for their 1939 Model would have probably made me Pick this Model Projector over any other if I was purchasing New Projection Equipment in 1939. Even though new features in their inaugural year don't always have the success they did during R&D; This proved to work as good as Designed and why CENTURY is still one of the Best Designed Projectors there ever was...  |  IP: Logged Sam D.

Even though it required 2 Actions it permitted Adjustable tension to be applied to the Intermittent Sprocket & Picture Aperature separate and independently. Separating these functions seems like a good idea but can result in a little more picture jump depending on where the int. is in its travel. Also relies on the sprocket and gate to be in perfect lateral alignment and this was never very good on later Century castings. This is one reason why Century's were never seen in US studios, also harder to run in reverse because of the gap between the gate and int sprocket.  |  IP: Logged Steve Matz Jedi Master Film Handler Posts: 672 From: Billings, Montana, USA Registered: Sep 2003 posted 08-17-2014 06:16 PM                     SAM: Were not supposed to have to run our Projectors in Reverse;it annoys the Audience And Just like in Life's Struggles we are to move Forward...  |  IP: Logged Sam D.

Day to day cinemas do not run backwards, but dubbing studios and dailies projectors did it from the beginning of film to perhaps 10 to 20 years ago. Happy now bitch?  |  IP: Logged Brad Miller Administrator Posts: 17775 From: Plano, TX (36.2 miles NW of Rockwall) Registered: May 99 posted 08-17-2014 09:36 PM                     I'm just waiting for Guttag to post a correction to the both of you.  |  IP: Logged Sam D.

Chavez Also relies on the sprocket and gate to be in perfect lateral alignment and this was never very good on later Century castings. Which implies that earlier castings were machined well. They weren't. Century couldn't machine castings consistently in any era. My favorite are things like sound guidance arms (penthouses and soundheads) where the lateral position depends on how far up/down the arm is. I'm sure Steve Matz was pleased (or will be pleased) to know that for the Simplex Millennium, Strong put the actual Century intermittent pad shoe and separate action in.  |  IP: Logged Gordon McLeod Film God Posts: 9532 From: Toronto Ontario Canada Registered: Jun 99 posted 08-18-2014 07:24 AM                     Brenkert copied the mid 30's ernamann design for the oil spray Oil spray was common in europe for a long time  |  IP: Logged
