[Hammarlund] SP-600 Tuning

Wed, 11 Dec 2002 10:15:03 -0500

Hi Gang,
    When I restored my SP-600 3 years ago, I lubricated the pivot points
only with white teflon grease, sold under the name Star Brite Teflon trailer
hitch lubricant. It is available in marine supply stores. It does not dry
up, migrate, go rancid etc. The SP-600 is still working perfectly after 3
years.  Just my  $.02 , Thanks Happy Holidays, Ross
