Both images have to be centered...then file at it. And I told them to buy turrets! Alignment on screen would take you only 5 min to do both formats !!!

I think I know where the film you refer to is stashed (we'll leave that unmentioned) and I'll dig it out and see where I'm at. Apreature plates might not be a problem as I think there's a plastic bag with about 50 of them in there so I should find something to work with. This of course will have to follow the platter retrofit I have to do in #4... The potts alpha is going to be upgraded to the latest and greatest - it's currently some morphodite thing they only built for a few months, decided it was crap, and quit building it. I've only had one brain wrap (caused by static cling, mind you) in the 6 months I've been doing this, and I made it a good one! I took out a few parts that can't be replaced. They say the new gravity rollers are nice to work with anyway, so it was a fun way to spend $200 of the boss's money!! Mark, did you only do the original install, or have you been back in for service?? I'm not sure what the service arrangements were, as no one is left there that has been there over a year, but I was under the impression the guys from American Cinema did some kind of yearly visit?? Just curious if I should be calling you or them.  |  IP: Logged Mark Gulbrandsen Resident Trollmaster Posts: 16657 From: Music City Registered: Jun 99 posted 03-27-2003 08:50 AM                     Hi Don, Yea, I did all the booths there back when it went to four screens, and then added the other two to go to 6 screens. Do Bob and John still run the place? I used to come back twice a year, or more often if needed to do service there. When things got really busy with me it was difficult for to go that far so they started to use MTS for service. I installed that Alpha thats way upstairs and it was brand new when it went in...shouldn't be a problem to fix if thats the one you are talking about. I haven't been in Manitowoc for around 10 years now, but really enjoy the area alot. Also did the installation at the West Bend Cinemas, and installed the plex in West Bend for "Uncle Buck Kolmeyer". It may be possible that someone before you got the plates mixed up..... As far as service I am definately too far to come there since I am in Utah and we are burried at work for a good part of th year. Steve Kraus who frequents this site may be able to reccomend someone competant to you since he is in Chicago and alot closer. Getting good service back there I realize is now a touch and go thing. I never reccommend anyone I don't know anyting about...try at your own risk! I don't know anything about American Cinema or what ever it was you mentioned, but be sure to hire someone for your service needs that has good credentials, the best test grear, and that lots of experience servicing. Your theatre location gets really busy alot of the time, and you are in a somewhat remote place to have to put up with too many problems. BTW: are you aware that Lawrence Of Arabia ran in 70mm in your theatre #4 for a month back when it was re-released??

Everything is bass ackwards! It takes a few minutes to get used to. What I did was to take a pinhole aperture plate and make a small nick on the edge of the hole then put it back in the projector to see what happened. Make a few more experimental cuts and observe the results. After a couple-three tries you'll start to see the cause/effect relationship of where to make "cuts" in the edge of the plate. After you have done a few plates it gets easier. Just go slow at first and you will succeed.  |  IP: Logged Don Bruechert Mmmmmmmmm, bird!

Bob generally does the bookings, sends us a schedule (usually needs a tweak here and there), and hangs out on Friday and Saturday nights. Otherwise we communicate mostly thru the fax. The only thing I know about John is he fixes the roof... The Alpha in #4 is the one I killed - it was their first attempt at auto-something or other - in order to flip to rewind on all our alphas except that one you must flip a switch. #4 has some kind of bogus microswitches in the return roller assembly that flip it into rewind mode whenever film is present in the roller (and the variac is up). The rollers pivot to shut off the switch, and are spring loaded. I wrecked the spring and some other nit-shit pieces of the rewind for the middle platter. The new kit I need to install doesn't pivot, but works off of gravity whenever tension is on the film in the rewind. Looks like it will be pretty slick. #3 works great for me, but everyone else hates that booth and say's it's haunted - that is the original booth at the top of the tower. Didn't know about lawrence... not my kind of flick anyway, but did notice the wierd sprockets on that projector. They are 35MM sprockets, but it looks like there is a lot more shaft there than needs to be... I assume that accommodated the large sprockets for the 70MM... That was supposed to be our "Super Deluxe" booth according to Bob. #4 and #6 support interlock, but I have never seen it set up. I'm also trying to figure out how to change all the burned out light bulbs in the automation remotes... annoying little bulbs those are... I know a couple of the guys at American Cinema and they seem to know our stuff pretty good. I called down there around Xmas because the PS failed in our CP50, and the guy knew just what I had... Even knew where the spare was hidden.... I've never been there when any of those guys have been around tho...  |  IP: Logged Mark Gulbrandsen Resident Trollmaster Posts: 16657 From: Music City Registered: Jun 99 posted 03-27-2003 10:21 PM                     Actually we installed another 70mm projector just for the run of Lawrence, I think it was a Cinemeccannica VIC 10. Da Boys always wanted to run some 70mm there.....so we did. They did pretty well for Manitowoc!! Bob is still doing the same thing as when I used to come up there...John...well, I donno...the roof ha? I'm surprised that he would even climb up there..... Sounds like your guys know things ok. Just keep em comming up there and straighten up all the nitty little problems that exist. The covers snap off of those remopte buttons...be careful doing so, and just use your finger nail or a tiny screw driver. The lamps are special and you may have to get em down in Brew Town at the electronics supply. Mark  |  IP: Logged Don Bruechert Mmmmmmmmm, bird! Posts: 340 From: Manitowoc, WI, USA Registered: Jan 2003 posted 03-28-2003 08:45 AM                        I got the caps off with a needle nose pliers, but the lamps are recessed into the buttons and we haven't figured out how to get them out. We have similar lighted buttons at the hospital where my day job is, and they have a special removal tool, but of course it is too big for these I don't know if they screw out or pull out, so I don't want to twiddle with them too much....  |  IP: Logged Paul G.

If your buttons are not lucky enough to ahve the ejectors then a tweezers will work. Paul is right on the lamp....the one on the right in the photo. Mark  |  IP: Logged Paul G. Thompson The Weenie Man Posts: 4718 From: Mount Vernon WA USA Registered: Nov 2000 posted 03-29-2003 01:45 AM                     Actually, since I busted a bunch with a needle-nosed pliers, how about using a windshield washer hose or a small vacuum hose with a little dab of super glue in the inside. Just simply slide your hose over the bulb, let the glue set, and "give 'er a yank." Then take a scissors and whack your old bulb and hose off, and prepare for the next one. OK, Phil....keep it clean, please. Seems like that might be a sure-fire method of getting that SOB out of the socket if you don't have the ejector tab as Mark mentioned.  |  IP: Logged Phil Hill I love my cootie bug Posts: 7595 From: Hollywood, CA USA Registered: Mar 2000 posted 03-29-2003 02:12 AM                  "Keep It Clean"... Gosh Paul, I'm sure I have not a clue what you mean. I have had success with using a "bulb-type" solder sucker (or a baby's ear cleaner thingie) with the tip cut down a little. I've tried the long-nose pliers thing but most times they just slipped or broke the lamp...even with shrink tubing. They do make a rubber "tool" to extract those pesky lamps, but I can never find one when I need it! >>> Phil  |  IP: Logged Paul G.

My tool works just fine for removing bulbs.  |  IP: Logged
