[QUOTE="wwcanoer, post: 13743, member: 706"] Possibly the rest of the story. A week, and a couple castings later, after I did that failed custom abutment, I thought the spring on my machine had broken. You know the feeling, you go to wind it up, and nothing happens. Take everything apart, spring (probably 24 years old) looks okay, but switch it out for a new one just to be on the safe side. Reassemble everything, but it still won't wind. Call the tech help people at Kerr, and after about an hour on the phone with them, trying this and that, discover that the pin on the shaft that the arm sits on had sheared off. It must've taken a few castings for it to finally give, as the inside of the hole looked like somebody had tapped it. That would also give me the turbulence issue I'm sure. But that also explains why it was such a pain to get the arm off of the shaft. I got the impression this does not occur all that often, but after playing with the darn thing for three hours, it's up and spinning again. In case you're wondering, switched abutment design from a custom waxed to a stock abutment. So much easier. Carol [/QUOTE]
