[QUOTE="rough2cut, post: 115674, member: 3816"] I like type metal. It does all,but is a little higher maintainance than most laps and subject to more wear and tear. And yes it builds up a layer eventually needing a skim to restore good polishing. But Im making them different. I cast them then compress them at 400 ton in my press. If you give it a good whack with a hammer it breaks up instead of bending. This closes the grain making a better type metal than others. I also do this to tin making it as good as rolled tin like crystallite and having it alloyed removes the rippling to a fair extent. Fosskieract you can name that lap here its safe to have your say without the threat of removal as long as its contructive. Any laps a good lap as long as it keeps you faceting. Not many have mastership over a ceramic lap. I like cutting cabs on my faceting machine. In fact I haven't owned a cabbing unit since I was 10 years old. It takes me about 12 minutes to cut an agate cab 30 x 22 oval. [/QUOTE]
