Author Topic: Improving payout on AW3 brains Nicholas Simmons Film Handler Posts: 6 From: Walnut Creek, CA Registered: Jun 2004 posted 07-24-2004 12:10 PM                     I have had similar problems with AW3's (no springs). I sometimes use the aluminum antistatic rollers to determine if the outter brain rollers are at fault, since the amuminum ones are not likely to get warped or bent. On another note, is there a correct way to adjust the height of the brain rollers? Could that maybe help?  |  IP: Logged Brad Miller Administrator Posts: 17775 From: Plano, TX (36.2 miles NW of Rockwall) Registered: May 99 posted 07-24-2004 12:20 PM                     The height? Are you referring to the occasional instance where the film isn't passing through the stripper rollers dead centered? If so, washers below the shafts to the rollers works and is a one time fix. That won't have any bearing on a bouncy payout, although if the rollers don't fit squarely together a thin washer below one of the shafts (obviously as needed) works well.  |  IP: Logged Cory Isemann Jedi Master Film Handler Posts: 500 From: White Plains, MD, USA Registered: Jun 2004 posted 07-24-2004 01:37 PM                        I was having sag problems and I just mounted an interlock roller to the wall. Seems to be working so far.  |  IP: Logged Dominic Espinosa Phenomenal Film Handler Posts: 1172 From: California, U.S.A.

I assume this is becuase of years of use the rollers have worn down and need to be replaced? We have a few that are causing scratches oposite the soundtrack because of low riding rollers. I've spaced them with washers and it's better but I'm thinking we may need to do something a bit more permenant. Also, in our big house all 3 brains (AW3 with stationary center feeds) have skinnier stripper guides. They've barely got a "ledge" like every other one I've seen. Are these new or something? Incidentally the big house never scratches prints like the other ones do and I think those have a direct relation to it.  |  IP: Logged Aaron Sisemore Flaming Ribs beat Reeses Peanut Butter Cups any day!

The newer ones have the thicker 'ledge' and the newest ones have the bevel on the inside part of the 'ledge'. -Aaron  |  IP: Logged Dominic Espinosa Phenomenal Film Handler Posts: 1172 From: California, U.S.A. Registered: Jan 2004 posted 06-20-2005 01:29 PM                     Anybody know why they changed it? It seems like the older ones don't get as dirty so easy or damage the film as easy. What gives?  |  IP: Logged Louis Bornwasser Film God Posts: 4441 From: prospect ky usa Registered: Mar 2005 posted 06-21-2005 03:33 PM                        At Christie, designs change with the seasons.

Registered: Jan 2004 posted 06-22-2005 01:55 AM                     I've been tweaking roller heights and stuff for months trying to get everything perfect, on some it seams like the rollers have had to come up quite a bit to quit scratching the edges of prints. So far I think I'm doing a lot better though. Is there some secret I'm missing?  |  IP: Logged Brad Miller Administrator Posts: 17775 From: Plano, TX (36.2 miles NW of Rockwall) Registered: May 99 posted 06-22-2005 03:48 AM                     First, split them apart as much as the movement will allow (it's not much, but plenty). Second, unless you have an actual burr or are using the old skinny posts from the 70's era, the scratching is not coming from those posts. Look elsewhere.  |  IP: Logged
