the post about tumbling media reminded me of this question that I have been meaning to post. I have a customer who has a spin polisher that uses corncob media with an abrasive impregnated into it. Problem is that the media wears out at a very fast rate and is supposed to be replaced so frequently that the cost per part is out of line. He has messed around with making his own media but hasen't gotten far. Does anyone have specific info as to the ingrediants and techniques for doing this? Thanks. I think he said the specified media costs about $1.30 per pound, plain cob is like 20 cents if I understood him correctly. Abrasive has got to be pretty cheap per pound of finished media since it would be a small portion.
