Here are a few snapshots of various pivotal phases in my Garrard 301 project.

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.

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.
