Platter assist (i.e. push start)?

Is this a pointless technique? I believe I read somewhere, for start up, it reduces the torsional forces on the belt and or motor, thus extending their life span.

groovy.......I just push the start button on my Michell Gyro SE motor and let it do its thing. I keep two fresh belts on hand so I have no worrys about tortional forces on the belt. If it shows signs of not performing properly, on goes a new belt. My RoadRunner rpm display keeps me informed of what the platter is doing.

Old tables use to have a hand crank maybe they could bring that back for start up. Then the rest of the world would know we are nuts.
 
Some tables were designed from the get-go to require a little hand push. The Nottingham tables come to mind because the designer Tom Fletcher used low torque motors feeling that they were best suited to maintaining accurate speed.
 
No push required with my VPI Classic 2 for spinning 33 1/3 RPM LP's, but I try to remember to push start it for 45 RPM and for sure when using the heavy periphery ring at either speed.
 
I replaced my VPI rubber belt with a silk thread. Soundwise it is much better, but does require a speed controller (not just a drop in replacement). However, I do need to give the platter a little push at start up because the string just doesn't grip the platter like the rubber belt did.
 
Bob...that's because the rubber belt slightly stretches and compresses in operation...The silk thread is more stable, but a pain to use. That's why Harry invented the rim drive, which does away with that stretchy belt, but is consumer friendly.
 
My AMG v12 has a screw down record clamp. I just finish the attachment of the clamp with an extra twist to get the platter spinning then hit the start button.
 
I always give my platter a little spin before turning it on. The Well Tempered belts are extremely thin so it's my belief that I'm extending the life of it.
