Comments On Jan 23, 2013:The bean and matrix are well adhered, but the matrix is softer than the bean and the bean tears out taking matrix with it when turning. The problem is worst before the blank rounds out, but the problem continues the thinner the blank gets. I failed on three attempts to turn the blank. In the end I found success by roughly rounding the blank with a belt sander and finishing the job with increasingly finer sand paper. The matrix readily plugs up sand paper, but it can be done.
