Winggo,
Why not try a new spindle bearing and shaft for the SL-1200mk2? It will cost you less than $30 from KAB USA ( http://www.kabusa.com/ACCESSS.htm#pg2a ). The spindle bearing is a massive 1/4" polished stainless steel shaft closely machined through a 1" long bronze bearing. See a picture at http://www.kabusa.com/gif/spindle.jpg .
Please tell us more about your design.
