Author Topic: Progector to sound head mounting Mark Gulbrandsen Resident Trollmaster Posts: 16657 From: Music City Registered: Jun 99 posted 02-04-2005 09:29 PM                     Hi Justin, Sounds like it may be the right one. Its the right thickness and if its black... then probably. A pix would help alot! There should also be a large hex shaped ecentric that goes through the plate right behind the head thats used to adjust the drive gear mesh.... The pin on the ecentric fits in a slot on the top of the sound head. if the ecentric stud is gone from the plate the approx. 1/2" hole for it should be there..... And yes the plate is attached from below with two 3/8 x 16 countersunk allen head screws. Hope this helps! Mark  |  IP: Logged Steve Guttag We forgot the crackers Gromit!!!

My dusty memory seems to think the ones I've had to deal with are "slotted" just to make it more difficult.

Perhaps someone in both the Midwest area and the Mountain states area was smart enough to throw the slotteds into the verticle file....

Well, we did go to Wolk and got an adapter. It was a little off in that the Brenkert was a little lower than with the RCA shound head. We fussed with it and got the projector almost up to were it was. Then a little alignment of the Knisley lamphouse and the picture was just as bright and even as it was before. It has run just fine for the past two years or so. Now, it's a moot point as we have added a BACP penthouse dolby reader and a CP-650 to our lineup. Now the Kelmar reverse scan LED reader in the Simplex is just backup to the digital. Thanks for the interest and suggestions.  |  IP: Logged Justin West Master Film Handler Posts: 271 From: Peoria, IL, USA Registered: Jul 2001 posted 02-05-2005 10:18 PM                     Thanks, all, for your input. On this C, the plate was attached with "slotted" inset screws...large headed and I am going to have to find a giant flathead screwdriver to get enough leverage or torque on them to turn 'em without tearing up the slots!  |  IP: Logged Mark Gulbrandsen Resident Trollmaster Posts: 16657 From: Music City Registered: Jun 99 posted 02-06-2005 01:51 AM                     Justin, It is not at all difficult to loosen those slotted screws and it can be done without damaging them. Lay the head on its side and with a screw driver thats half the width of the slot put the drivers blade against half the slot at as much of a right angle as possible and use a small hammer to tap the screws (sideways) to loosen them up. These screws are hardened and this works every time without damaging the screws. Replace the screws with 3/8-16 Allen heads of the same length as all "smart" technicians will do. This will allow very easy removal of the plate in the future.
