[Hammarlund] SP-600 Tuning

Tue, 10 Dec 2002 20:11:08 EST

One last caveat, NEVER, EVER use oil on the geartrain of a SP-600, it tends 
to migrate towards the idler friction wheel. It is brass, and tends to absorb 
oil. I have used tape head cleaner (the freon type) with sucess also. The 
SP-600 manual cautions against using oil or lubricant, but of the 19 i have 
owned over the years, ALL of them had oil/lubricant on the gears when 
received here.

<< Hi Dave & Andy, et al,
    I just saw both of your msgs.  I'd add 1 possible solution that might be
easier to do tonite - make sure the surfaces of both "wheels" are
scrupulously (sp?) clean.  Any oil on there will cause the problem, get it
off by washing with detergent or use acetone.  Many  solvents will still
leave a residue unless you do it a cupla times with a clean cloth.
    Andy, why don't we put your fix (with the cleaning too) on the website
with some pix?  I've been meaning to for a while, this question seems to
come up regularly.  I can take pix right now (tomorrow).
