I am not a mechanical engineer... so what is virtual mass?

it's a bunch of bs. :d
While the Hockey Puck is a nifty idea for a substitute, I don't think it even approaches the function of the clamp-style retainer. With the clamp, you can push down hard on the record and then tighten the collet, which gives you a superior amount of pressure on the record, thus eliminating any chance of resonance. I'd say you need at least the equivalent of 1 lb. of pressure to be effective?
By the way, I wonder why we still abbreviate pound or pounds with the LB, which is short for the latin 'libra', meaning scales or weights.
OT Alert: Good question that I never even thought of! Wikipedia's definition explains each of the terms, but not the history of how the two became married expect that "the Romans did it, too":By the way, I wonder why we still abbreviate pound or pounds with the LB, which is short for the latin 'libra', meaning scales or weights.
The word pound comes from the Latin word pondus meaning "weight". The abbreviation lb comes from the Latin word libra, meaning "scales, balances", which also described a Roman unit similar to the pound.
...Plus I'm a cheap sob and 40 bucks to me sounds a little steep.
To each his own.
In reading this thread I'm wondering about the thinner records you've come across with using a clamp, with so much down force in the center does the outer part of the disc bow up at all ?
With respect to an A/B comparison, hockey puck vs. new clamp/weight because I'm reluctant to press the puck into place on my suspended t/t I can't be very helpful.
So your record is now not laying flat on the surface (platter), so what's the piont then ?

Well I disagree I'm using a jar lid that is drilled so You have to use force to get it took lock in place on the spindle and i know
I am wondering if you could provide a photo of this jar lid system you have worked out? This sounds intriguing.
Does the lid 'scratch' the spindle on your TT after multiple uses?
