Author Topic: Kelmar C/O on a DP75 Sean McKinnon Phenomenal Film Handler Posts: 1712 From: Peabody Massachusetts Registered: Sep 2000 posted 03-25-2010 01:14 PM                        I beleive someone posted on here that they had succesfully retrofitted a Kelmar changeover on a DP75. If possible could I get some help as to how to accomplish that and possibly a location where that has been done? My boss is interested but would like to speak to someone where this has been done to find out if they are happy with it. I understand if you don't want to give out that info but some direction as how to retrofit the Kelmar on the DP75 would be very very appreciated. Thank!  |  IP: Logged Stan Gunn Expert Film Handler Posts: 176 From: Clematis, in the hills near Melbourne Australia Registered: Aug 2000 posted 04-02-2010 08:59 PM                        Hi sean I service 4 dp75s and think the standard system altho a little fiddley is the best way to go.if the solinoids are faulty just about any sol of the correct voltage and torque would do. Come to think of it Kelmars could replace current sols in the same position, but why make life any harder than it is.

Some machining is required to both the change Over and the gate frame to make it fit correctly... and it barely does at that but works better then the originals. Many Hollywood DP-70's have been retrofitted with Kelmars including those at the Academy Theater.

Fortunately there are far more DP-70 still running than there are DP-75. It may still be possible to adapt something in terms of the Kelmar to the DP-75 and I am pretty resourceful doing these sorts of things.

I sent Kelmar pics of the machines and all the relevant parts and linkages. The original electronics were replaced previous with a home brew set-up that is not adequate for our c/o type of operation. One option is to go back to the original Kinoton electronics but we are exploring all other options.  |  IP: Logged
