Interesting responses from the very two people I started to address this post to in the first place; Doug and Ken.
Ken, I'm going to try the epoxy thing tonight and see what happens before sending the handle to Doug.
BTW, the superglue on the checkering definitely makes for smoother diamonds. Thanks for the advice.
Doug, I haven't had any noticeable vibration with the Dem-Bart handles and cutters. Whenever I did detect it, I just switched direction and the problem went away. I remember Joe Balickie saying the same thing about the carbide cutters; too sharp at first. He said they definitely got better with some wear on them and they lasted forever. If Ken's suggestion doesn't solve the problem, I'll send you my clear view handle.
