Author Topic: Flywheel problems on my Century Projector Monte L Fullmer Film God Posts: 8367 From: Nampa, Idaho, USA Registered: Nov 2004 posted 07-22-2007 09:07 PM                     quote: Mark Gulbrandsen you'r drivin slow in the left lane again.... .... ..been told that one before. Guess,I'd better find the gas pedal and use it, or lose it . .. Let's speed this one up a bit then: Would a tight intermittent shaft coller cause any of these above conditions?  |  IP: Logged Mark Gulbrandsen Resident Trollmaster Posts: 16657 From: Music City Registered: Jun 99 posted 07-22-2007 10:14 PM                     Yes, possibly.  |  IP: Logged Randy Bowden Expert Film Handler Posts: 146 From: Portland, OR, USA Registered: Aug 2000 posted 07-28-2007 01:27 PM                     This has been an interesting thread. don't get me started on the poor quality of the metal that strong uses. I have had quite a few of the strong built simplex intermittents in my shop where both flywheel screws had completely sheared off. I always replace them with the lavezzi version. I also like to use brand new lavezzi oil drain screws on every century intermittent that I rebuild, the strong version is rather easy to snap the head off. How would you like to deal with that in the field? BTW I have NEVER had a single lavezzi oil drain screw break on me.

Absolute crap!

I know Lavezzi builds the Ultra but did they actually design the thing? BTW I have a nice upgrade to that crappy bearing design. Perhaps sometime in the future I will post on this with pics. Lavezzi is the manufacturer of a number of precision projector components, ie. starwheels and cam shafts. they sell the oil drain screw for the century as part number sc-1010 they also sell the washer stack that goes along with it. visit lavezzi.com sometime and you will find online photos of all the parts they are stocking. All in all I have very few complaints about Lavezzi.  |  IP: Logged Louis Bornwasser Film God Posts: 4441 From: prospect ky usa Registered: Mar 2005 posted 07-29-2007 06:18 AM                        Lavezzi: Like UPS, most of the time they are very very good; once-in-a-while they are very bad. Luckily the good is 99.5% of the time.

Haven't had all that much trouble with outboard bearings in Ultramittents in the last few yers but would be interested in seeing your solution. You're right on folks ordering bearings from Strong as replacements... There are much better bearings available just down the street in many cases. Another VERY GOOD reason not to use the Strong Service Organization for any booth maintainance, very likely the same crappy parts will be re-installed!!!

I'm going to check out Lavezzi right now.

(yea, STRONG .. pretty scary stuff ...) -Monte  |  IP: Logged Michael Moore Expert Film Handler Posts: 188 From: Dover, DE / USA Registered: Jun 2006 posted 07-30-2007 09:13 AM                        These days you don't need numbers on the race just a good micrometer. does anyone know of a good source for fillister head bolts and screws? local hardware stores do not have them. I know I could use socket head cap screws but I like fillisters. I know of one source, fillisters any idea of a better one?

I guess I spent too much time in woodshop.  |  IP: Logged Steve Guttag We forgot the crackers Gromit!!! Posts: 12814 From: Annapolis, MD Registered: Dec 1999 posted 07-30-2007 11:49 AM                     There are more head types than those too. Michael, you will want to go to an industrial supplier rather than a local shop to get the type of hardware you want. Steve  |  IP: Logged John Hawkinson Film God Posts: 2273 From: Cambridge, MA, USA Registered: Feb 2002 posted 07-30-2007 02:06 PM                     On the topic of alternative bearing sources, Monte writes, "especially if you know the bearing number-which is stamped either on the outer race or the bearing shield." Michael Moore then says, "These days you don't need numbers on the race just a good micrometer." Err, my understanding is that neither of those pieces of information are themselves sufficient. Correct me if I am wrong, please. Replacing a bearing requires knowing the bearing grade (e.g. ABEC 7) as well as its dimensions, and a micrometer does not give you the grade. Furthermore, often the numbers stamped on the bearing do not give you either, though sometimes they may. --jhawk  |  IP: Logged
