The small pulley is for the 600 RPM motor. The larger pulley is for the 300 RPM motor. At least that's how it worked out on the Scout/Scoutmaster/Aries motor assemblies. You can clearly see the black nitrile belt in the video you linked. An idler drive has no need for a belt connecting it to the platter. The pulley is not touching the platter.
VPI Classic 3 IDLE drive
Hi all,
I have as VPI Classic 3 I bought about 1 year ago and I was lately looking at the pictures on their website and notice that the classic now has an idle drive.
I also noticed that the platter has grooves where the belt goes, while mine doesn't.
I then called vpi and asked them if the idle drive was ready to be purchased for upgrade but They told me it wasn't.
Today while looking on you tube, I saw a video with a classic 3 with the same device I have seen on the website.
It is basically a larger pulley that touches the platter thus functioning like a rim drive however it still uses the belt along with it.
I was wondering if anybody here can help understand if this upgrade is finally available.
Thanks.
Stefano.
