I believe Wolk still has new pinch rollers. That is a "sure-fire" method of having it clean. It is easier to keep the roller clean with daily cleaning rather than waiting for it to accumulate and embed. Be careful about using ANY solvents around it as liquids are likely to wick into the bearings or onto the shaft and cause them to fail. -Steve Edited to note the mistake in part number (Simplex versus RCA).  |  IP: Logged Ian Parfrey Phenomenal Film Handler Posts: 1049 From: Imbil Australia 26 deg 27' 42.66" S 152 deg 42' 23.40" E Registered: Feb 2009 posted 12-22-2010 07:11 PM                     ...or remove the roller as per the instructions in the tips section and get the centre section undercut leaving two thin "tyres" onn either side of the roller.  |  IP: Logged Victor Liorentas Jedi Master Film Handler Posts: 800 From: london ontario canada Registered: May 2009 posted 12-22-2010 08:49 PM                     Hi Ian Have you done what you described before?  |  IP: Logged Gordon McLeod Film God Posts: 9532 From: Toronto Ontario Canada Registered: Jun 99 posted 12-22-2010 09:02 PM                     steve he has SH1000 not RCA  |  IP: Logged Ian Parfrey Phenomenal Film Handler Posts: 1049 From: Imbil Australia 26 deg 27' 42.66" S 152 deg 42' 23.40" E Registered: Feb 2009 posted 12-22-2010 11:19 PM                     Victor. I have, many years ago, on an RCA Photophone soundhead- model number I can't recollect but most likely the 1050. The tricky part is to make sure the turning tool used to undercut the roller is VERY sharp and to take small cuts. Also make sure there is a 2mm or 5/16" tyre left at either end of the roller. If turning is not your forte, then perhaps taking the part to a shop to do may be an option. The advantages I found were little oil marking on the picture area Tension is still kept on the film over the drum so little slipping occurs Wow and flutter as per standard unmodified roller. As this was done many years ago (about 15-20), I can't vouch for its affect on any basement digi readers, but for analogue, it's the duck's guts, very easy to do and you don't need any new parts. To rid the roller of oil I used printing press wash before I turned the roller down, but in the US I think there is a product called 'California Wash' that does a similar thing and will NOT damage the rubber roller. As it stands Victor, give it a bash and see what happens. That soundhead is still running to this day and hasn't missed a beat.  |  IP: Logged
