Author Topic: FP20 take up not up to speed. Alan Gouger Jedi Master Film Handler Posts: 501 From: Bradenton, FL, USA Registered: Jul 2000 posted 06-21-2010 07:52 PM                        I have an FP20 and the take up is not up to speed so the film spools off to the floor as the take up reel is not fast enough. The clutch is tight with no slippage. Unless I am missing something the rest of the take up is chain driven so I do not see where there is anyway for this to not be up to speed. Any ideas are appreciated. Regards.  |  IP: Logged Gordon McLeod Film God Posts: 9532 From: Toronto Ontario Canada Registered: Jun 99 posted 06-21-2010 08:55 PM                     The FP20 take up is for a 5" take up hub  |  IP: Logged Alan Gouger Jedi Master Film Handler Posts: 501 From: Bradenton, FL, USA Registered: Jul 2000 posted 06-21-2010 09:31 PM                        Gordon the one I am using the take up spindle is in the 2k position. I measured the hub of a typical 2k reel and it looks like it is 4.5". I see Goldberg makes one with a 5" hub time to place an order. Thanks for the help.  |  IP: Logged Steve Guttag We forgot the crackers Gromit!!!

But yes, the standard take up is for 5" and larger. Watch out on the "clutch is tight with no slippage" thing...clutches are supposed to slip...that is how they work. Make sure the take up is not too tight once you get the correct reels.

Ended up putting a bit of scrap film on them, and then a layer of tape, to enlarge the hub slightly.  |  IP: Logged Richard P.

Operating FP20s in a lab, it is something of a nuisance not to be able to take up on 3" or 4" cores with split reels. It is the speed of the takeup with its chain drive, and doesn't seem to have anything to do with friction.

Steve can get you part number and price...BTW if you can Steve please post that info here or PM me too as I would like to know how much for my machines at UC Irvine.  |  IP: Logged Gordon McLeod Film God Posts: 9532 From: Toronto Ontario Canada Registered: Jun 99 posted 06-23-2010 06:58 PM                     The best route is to fit the machine with torque motor takeups like the magnatech version of the FP20 studio machines  |  IP: Logged Bill Gabel Film God Posts: 3873 From: Technicolor / Postworks NY, USA Registered: Jan 2002 posted 06-23-2010 07:09 PM                     I have a set of the Magnatech version and have no problems with the takeups.  |  IP: Logged Alan Gouger Jedi Master Film Handler Posts: 501 From: Bradenton, FL, USA Registered: Jul 2000 posted 06-23-2010 07:50 PM                        Was the Magnatech version the entire machine or did or do they sell a conversion kit? Any pictures? Thanks guys.  |  IP: Logged Gordon McLeod Film God Posts: 9532 From: Toronto Ontario Canada Registered: Jun 99 posted 06-23-2010 09:24 PM                     MagnaTech did mods to the machine and sold it as a studio machine  |  IP: Logged Mitchell Dvoskin Phenomenal Film Handler Posts: 1869 From: West Milford, NJ, USA Registered: Jan 2001 posted 06-24-2010 08:29 AM                     The MagnaTech mods to the FP-20's, at least the ones at the Landmark Loews Jersey, consisted of of replacing the feed and takeup slip clutches with electric motors that provide back tension on the feed, and adjustable (1000' or 2000' reel settings) takeup torque. Same concept as an old reel to reel tape deck. They also made a slight modification to the film gate, so that the skate is moved slightly back at the top when the projector is run backwards, so the film does not jam in the gate. Personally, I have never run them backwards, so I don't know how well it works.  |  IP: Logged
