We had a few of the regular rollers on the MUTs and after a while the friction of the high speeds began to bore out the center causing the roller to wobble like crazy but it didn't build the film tight. As far as the tension I have tried a few things in the past. Although others will disagree with this it is worth a shot. Try taking the belt off of the motor and wheel and see if that helps building up. On breakdown, see if you can separate the motor from the platter. CAUTION: This should leave you with no tension so you have to accelerate and decelerate very very slowly, otherwise your shit is going to fly everywhere. Alright guys, bash the hell out of me now.  |  IP: Logged Brad Miller Administrator Posts: 17775 From: Plano, TX (36.2 miles NW of Rockwall) Registered: May 99 posted 03-23-2003 06:11 PM                     Never, ever, ever, ever pull back the motor from the platter during breakdown if you don't want to damage the film. (Christie, SPECO and Kinoton models only. All other platters are carelessly designed which frequently damages film during breakdown and as such this does not apply to them.) If you have to pull back the motor to solve some other problem, you need to solve that problem and not rig other things to get by. Also, loading tension isn't that big of an issue. If it winds a little loose, big deal. The film will pay out from the middle of the roll just fine if it isn't tight. This only affects the careless operators who build on one specific platter and then move the print before it is ran at least one time. Prints should always be built on the platter where it will run it's first showing. Is that harsh enough for you? Don't make me add you to the "you suck" list. Be sure and slap your trainer next time you see him and tell him it was from me!  |  IP: Logged Manuel Francisco Valencia Expert Film Handler Posts: 151 From: Oklahoma City, OK, USA Registered: Dec 2000 posted 03-23-2003 06:48 PM                     As I said I "tried a few things in the PAST." This isn't a practice of mine but I did do it so I will take the good with the bad, I am a big boy. Mistakes shouldn't be hidden but learned from.  |  IP: Logged Brad Miller Administrator Posts: 17775 From: Plano, TX (36.2 miles NW of Rockwall) Registered: May 99 posted 03-23-2003 08:26 PM                     So did you learn from them? If so, it would be nice if you would refrain from posting known bad suggestions to the readers who may not know better.  |  IP: Logged Manuel Francisco Valencia Expert Film Handler Posts: 151 From: Oklahoma City, OK, USA Registered: Dec 2000 posted 03-23-2003 08:44 PM                     My apologies.  |  IP: Logged Paul Konen Jedi Master Film Handler Posts: 981 From: Frisco, TX. (North of Dallas) Registered: Jun 99 posted 03-24-2003 09:04 AM                     Manny, I actually took the roller assy that adjusts to the deck that you are using and turned it upside down to replace the roller at the bottom of the MUT. This assy is a lot more studier than the roller on the thin piece of steel that would start to warp under tension. So, my answer is TWO high speed rollers on my MUT. Brad, Can you expand on lubricating the axle bearings? I don't think that anyone, including Christie, told us to do that.  |  IP: Logged Brad Miller Administrator Posts: 17775 From: Plano, TX (36.2 miles NW of Rockwall) Registered: May 99 posted 03-24-2003 11:45 AM                     Take the decks off and lubricate the bearing that sits at the base of the axle (or sticks to the bottom of the deck, depending). I've been using high speed brake lube which has worked well for me.  |  IP: Logged
