Corrections to two of my previous posts.
a WallyVTA, which surprised me with how much better it made things.
I meant to say WallySkater.
And regarding the Graham counterweight:
The weight is slid along the track by an accordion-like mechanism that expands or contracts.
That’s inaccurate. It is propelled along a threaded rod that functions like a screw. But the issue of resonance and decoupling remain.
Just wanted to set the record straight.
