Skeletal vs Plinth style turntables


I am pondering a new plinth design and am considering the virtues of making a skeletal or closed plinth design. The motor unit is direct drive. I know that as a direct drive it inherently has very low vibration as opposed to an idler deck (please do not outcry Garrard and Lenco onwners coz I have one of those too) but simple facts are facts belt drive motors spin at 250rpm, Lencos around 1500 rpm, DD 33 or 45 rpm. That being the case that must surely be a factor in this issue. What are your thoughts. BTW I like closed designs as they prevent the gathering of dust.

(call it "arm pod drag").

LOL - Good one Lewm. Learn something new every day.

Kind of sounds like a new dance to me ? Ok everybody
off your asses and onto the dance floor, Lets all do the
arm pod drag ....

You shuffle across the floor with the front leg leading
(closest to the TT)).... the back leg dragging...

I re calculated the train thing.
Assuming the following
Make it a 100gm sticky snow ball traveling directly towards the train at 100 KPH, to make things easier.
Make the train, 1000 tonnes, also traveling at 100 KPH
The snow ball hits and sticks to the front of the train.

The train will slow to 99.99998 KPH, more or less. I accept that I may have an extra or too many 9's

Conservation of momentum.

You did ask!

Re the pivoted arm/speed question. It makes sense, since the arm is moving forward relative to the radial line for some of its travel across the record.

"The song, I got U BABE".
My dreams, shall we say, are usually more exciting in content.

Cheers.
Poem. By Henry Gibson

Was a man named Henry, poor fellow
His tonearm pods were made of jello
They slipped around like on ice
Watching them twirl was quite nice
But his music still sounded like it was supposed

Peace,
