Yeah....But what probably caused the decomposition of John's parts was some trace amounts of some 110 octane habanero chili that had previously etched its way into the Tupperware....You gotta be careful with Tupperware and habaneros! -----Original Message----- From: phono-l-bounces at oldcrank.org [mailto:phono-l-bounces at oldcrank.org] On Behalf Of Steven Medved Sent: Wednesday, January 24, 2007 10:31 PM To: Antique Phonograph List Subject: RE: [Phono-L] cleaning lead screw & half nut Hi John, Excellent point, I soaked a mainspring in WD-40 and after a few months it was pitted. If you are going to soak things for a long time use regular oil, it worked well for me when I soaked a spring and it made it easy to clean.Steve > And use care with solvents. Years ago I left some really greasy motor parts from an Edison Standard in a tupperware container of engine degreaser. It took me some time to get around to finishing the project. By that time, some of the parts had literally rusted away in the degreaser!!!!> John> > Steven Medved <steve_noreen at msn.com> wrote:> To clean leed screw, you can use a toothpick or brass pin to get in the grooves, it depends on the type of crud that you have. If it is just dried grease you can soak it in mineral spirits or oil and wait a few days as this makes removal easier. A dremel tool works wonders a plastic wire wheel or other attachments works wonders. I polish the carriage rod in a drill motor and clean out the hole in the carriage where it goes. A Q-tip in the dremel and metal polish works well in areas where crud has built up. > > Steve_______________________________________________> Phono-L mailing list> http://phono-l.oldcrank.org> > _______________________________________________> Phono-L mailing list> http://phono-l.oldcrank.org_______________________________________________ Phono-L mailing list http://phono-l.oldcrank.org -- No virus found in this incoming message.
