Hi S Clark,within the last few issues of Stereophile, Art Dudley did an article about rebuilding a Rek-o-cut turntable. It went about 2 issues long. Maybe not the last issue but the ones right before that. Might have some useful info that would help you. I recall many pictures he had about the idler wheel.S ,December 2012 and January 2013 are the right ones...take care...Mark Korda
