bearing is far from the end of the task here though. Every bit of linkage and
idler-positioning gear below the plinth level has to be cleaned, loosened up,
and each juncture either oiled or greased. One article by Loricraft cautions
that the various armatures that comprise the linkage are cadmium-plated, so
these should get minimal handling, and contact with skin isn't advisable.
... As noted before, the motor
condition of my 301 was well above expectation, and I've decided a few drops of
motor-assembly oil in the upper and lower bearing slots will do for a trial run.
The lower bearing is a little bit of a shot-in-the-dark, since you're kind of
firing up into it in order to let it trickle down to the center bearing pad. But
it gets there via gravity eventually.
If you have a basic working
relationship with a computer and printer, you can print up an exact, life-sized
template for a Garrard 301 plinth. I
taped my template sections to a window in order to line it up with light coming
through the paper from outside. There
are actual-size measurement segments in inches on the template that you can
double-check with a ruler once you’ve got it printed at the right scale.
( The template I was
using, in Acrobat Reader, was printing properly at approximately 95.49% of the
original diagram’s size. Obviously
this will vary but that gives you the idea of tweaking it down to the precise
At this point, I was still anxious to see if this project would have any potential, so the first platform I came up with is really just a jig in which to safely place the 301 mechanism for adjustments and lubing. As well as a first listen, which was by now imminent. The open-frame jig I ended up with was all that was necessary. The ‘armboard’ is basically a quick way to attach or detach an arm. The most useful part of the jig is the ability to work on the 301 from any side or even upside-down while avoiding damage to the mechanism below, or to the controls or spindle on top.

This long, cautious expedition through the mid-fifties intricacies of the 301 may have initially tempered my enthusiasm somewhat. There is a distinct sense of dragging a snoring dinosaur out of it’s lair --- one that you’re going to have to civilize and domesticate by force of will. But I’d been as cautious and complete as I could be, and I was now past ready to go.
