<p>[QUOTE="cpm9ball, post: 2336221, member: 24633"]Rusty, the debris doesn't have to be large, and it doesn't have to be metal. Every time another planchet is struck, the mixture gets harder and when more grease and debris adds to the mix, it gets harder and larger. After a while it gets to the point where it is harder than the planchet, itself.</p><p><br /></p><p>Chris[/QUOTE]</p><p><br /></p>
