Those things that could have been realy good but not realy made it all the way.

[QUOTE="Lance, post: 1010658, member: 20635"] [member=17918]JonnyP[/member], yes, I use Neodymium (rare earth) magnets for the reason that you are alluding to in that they offer far greater strength for size than ferrite magnets for instance. I tested various options including ferrite magnets, but the size of the ring required to lift the 17.5 Kg platter assembly was way too big, in the end a grade N42 Neodymium was perfect for my need. the other advantage of neodymium is that it remains stable, if memory serves it can lose about .5% of it's force in 100 years, so guess what, my TT will still work in a hundred years time!, might have used quite a few belts in that time though :) I am not familiar with the separators that you mention, but understand the concept, which will suit applications where space and size limitations occur. This is a fascinating field, excuse the pun, where would we be without magnets, certainly no turntables! [/QUOTE]
