Here are a few snapshots of various pivotal phases in my
Garrard 301 project.
(pre glue)
The last (below in color... ed.) and most current
version is a Baltic Birch stacked-ply plinth, a high mass design, with a
fairly wide footprint, and a low center of gravity.
On the
subject of gravity, an explanation of the clamping-press procedure is in
order. To get an absolutely square front-edge profile while laminating
with hot hide-glue, it was necessary to design a ‘kneeling press’ that
could be gravity-loaded, clamped, and then up-righted to cure. More
detail about this on the Plinth page of my Garrard Project site, titled
№ 6435 , linked below.
The two earlier plinths here are the simple servicing jig, a utility
plinth which can be positioned on any side for adjustments, even
upside-down, as the tall side panels protect switches and spindle. The ‘armboard’
in this case is a rudimentary bolt-on fitting to facilitate a quick arm
attachment for monitoring & evaluating adjustments.

(preliminary checks)
And the high-mass uni-plinth, chiselled out
of a solid section of laminated roof-beam and fitted with a sliding
armboard. This approach allows an internal shape that closely conforms
to the undercarriage of the 301, an aid to absorbing mechanical
resonance.
