Author Topic: Simplex E-7 Collectors Jim Henk Master Film Handler Posts: 364 From: San Diego, CA Registered: Feb 2006 posted 08-18-2014 01:56 PM                     quote: Day to day cinemas do not run backwards, There was a theatre in Glendora, CA years ago that designed their own automation system, and it did exactly that. While one projector (they were XLs) was running forward to show the feature, the other just reversed, and ran backward at standard speed through the projector to rewind the other feature. And they did it without damage to the print. Saw it myself. It worked. Talking with the owner, apparently they tried to sell the idea to some companies with no luck. Guys would come out, look at the system running, declare that what they were seeing in front of their eyes could not be done, and leave.  |  IP: Logged Mark Lensenmayer Phenomenal Film Handler Posts: 1605 From: Upper Arlington, OH Registered: Sep 1999 posted 08-18-2014 02:04 PM                     That forward-backward automation sounds like an Eprad Sword. A two-screener (Cinema North) was equipped with those in Columbus and they worked very well.  |  IP: Logged Steve Matz Jedi Master Film Handler Posts: 672 From: Billings, Montana, USA Registered: Sep 2003 posted 08-18-2014 02:57 PM                     SAM only brought up the Reverse issue because he wanted to "BITCH SLAP" me for no reason "lAST PERSON WHO DISAGREED WITH ME ON REVERSE OPERATION"  |  IP: Logged Mark Gulbrandsen Resident Trollmaster Posts: 16657 From: Music City Registered: Jun 99 posted 08-18-2014 04:27 PM                     quote: Steve Guttag Which implies that earlier castings were machined well. They weren't. Century couldn't machine castings consistently in any era. Um, wrong! The pre WW-2 Century C's were frickin awesome projectors, with everything machined perfectly. These are the only ones to go after if you want a really good Century. The main castings were some sort of ultra hard alloy too, not just cast iron or pot metal aluminum. The fronts of them are all but impossible to cut to fit a Kelmar turret and the surfaces are all extremely accurate. You have to have the fronts plasma cut if you want to fit a turret. I rebuilt a few dozen of these era Century's and never had to go back to repair one of them. The customer who was in Wisconsin claimed they were the best most reliable projectors they had ever bought.

If you don't think there is some massive Core Shift in a Cast Iron Engine Block than ask any Automotive Machine Shop Tech that has worked with BB Mopar Engines(i.e.383,426wedge,etc.) Try and remove the Camshaft out of these Blocks when they have over 50,000 miles. You will break it before you can extract it... Now these are blocks that are most of the time never reaching Temperatures of more than 220 Degrees. I don't know what Temperatures A CENTURY or any other Cast iron housed Projector obtain with say a 2 or 4k Lamp but I would assume the Projector head still gets extremely warm.I can see why there could possibly be an oil Leakage/warpage issue with Projectors using extremely Intense Lamps if this intense heat is transferred to the Head...  |  IP: Logged Will Kutler Phenomenal Film Handler Posts: 1506 From: Tucson, AZ, USA Registered: Feb 2001 posted 08-18-2014 07:11 PM                     Mark...maybe you were dealing with a high (chrome/white) alloy. Steve...agreed with what you said regarding older engine blocks. I also heard over the years that Detroit would throw new castings in the Great Lakes or in an open field for a few years in order to artificially age the material. Looking at machine tools like Atlas lathes...some people might think that they are cheap due to the die-cast gears and other parts. This engineering was intentional. If the machine was to "jam", the gears would shatter, thereby preventing chain-reaction catastrophic damage.  |  IP: Logged Sam D.

I apologize if this did not sit well as evidenced by your shout out to me in another topic. I get you like visuals. As to the posted picture; it's maybe beyond appropriate. This seems to show a Hispanic prisoner, beaten pretty severely by someone for reasons unknown. In case you have not noted my family name, you might want to reflect on this. I don't take myself very seriously, but with race relations at an all time low, a little sensitivity might be in order.  |  IP: Logged Mark Gulbrandsen Resident Trollmaster Posts: 16657 From: Music City Registered: Jun 99 posted 08-18-2014 09:09 PM                     Will... I think so. I have machined a lot of different alloys over the years, gobs of cast iron both new and old and this was literally like machining titanium. Pretty amazing stuff for 1938 era. I seriously doubt it was any sort of cast iron when I stop to think about it. Three or four sawzall blade's later I was perhaps a half inch into the stuff. They were also extremely heavy. I am about to toss that E-7 so if you want it all you have to do is pay packing & shipping from SLC. IM me your email and I can send you pictures. It's going to the dump this Saturday otherwise.

If you really want proper "Rock-n-roll" projectors...there is but one...Kinoton. The rest are just imitations. The AFI/Silver has been running that way since day one. Backing up through the machine at up to 100fps is no big deal and zero film damage...and quiet too. They use the EMK-1 automation (same as the CA21 of Pennywise fame) for their automated changeover/reverse shows.  |  IP: Logged Steve Matz Jedi Master Film Handler Posts: 672 From: Billings, Montana, USA Registered: Sep 2003 posted 08-18-2014 10:19 PM                     quote: Sam D.

SAM; I am far from a Racist;in fact one of my best friends is married to a Spanish Girl whose maiden name was CHAVEZ and I think the World of her As far as the Photo goes I never even gave a thought to what Race the Person was(Afro-American) I was just looking for a quick photo of someone that took some punches so no disrespect was ever intended... If you read the Real Story behind that Photo; he's lucky to be alive as far as I'm concerned; if I was involved he would look worse than he does... This Young Man was Sexually Molesting a young Boy that he was supposed to be Babysitting while the Father had some errands to Run. Well the Father returned Early and found this SCUM Molesting his Son and proceeded to do what you see in the Photo. The Father was not Charged with Anything;This Mutt is charged with Sexual Battery upon a Child and a bunch of other Charges. I have no use for Child Molesters and if it had been me in place of this Father; he wouldn't of had to worry about ever coming to Trial no matter what Race he was!  |  IP: Logged Will Kutler Phenomenal Film Handler Posts: 1506 From: Tucson, AZ, USA Registered: Feb 2001 posted 08-18-2014 10:37 PM                     Hi Mark definitely interested and e-mailed you at your Cinerama e-mail and also p.m.'ed you. Thanks! Have you ever tried to machine Naval brass? ! I love machining cast iron...there is one problem with machining sand castings, though. The casting surface often has a "skin" that contains casting sand...and that can wreck havoc on your cutters! Steve and Sam...I am anything but politically correct...I am not a moderator, but I think for the harmony of the forum, please edit/delete the latest posts and that picture. Cheers Kutler  |  IP: Logged Sam D. Chavez Film God Posts: 2153 From: Martinez, CA USA Registered: Aug 2003 posted 08-18-2014 10:49 PM                       Oy! Some of my friends are, fill in the blank.... I am good and know Steve did not mean offense. If Steve will keep posting eye candy of big block Chevy's and Eastman projectors and not actual human beings beaten to a pulp we'll all be better off.  |  IP: Logged Steve Matz Jedi Master Film Handler Posts: 672 From: Billings, Montana, USA Registered: Sep 2003 posted 08-18-2014 11:07 PM                     Time Limit is up!

Tore one down completely to give it a total cleaning and rebuild. Made it look good again..and ran very smooth. ... just that oblique gear setup - not made for polyester film. -Monte  |  IP: Logged Gordon McLeod Film God Posts: 9532 From: Toronto Ontario Canada Registered: Jun 99 posted 08-19-2014 10:08 AM                     For reverse operation remember the Victoria 8R that ran the reel backwards through the gate at 2x speed so a automated theatre required no rethreading  |  IP: Logged
