Wow! What a great test!
I look forward to reading your results!

Thanks very much, Bernie. But the report contains the results, that's all I got.
The conclusion is that the suspect chuck I received from another member performed dramatically worse than either of mine -- so badly as to be practically useless. I still can't say with certainty why that was. I do think I demonstrated the fact.
Recently a new thread came up on Sherline Yahoo raising the question whether as many users were experiencing holding problems with chucks purchased in the ensuing 5 years. This was never determined, it would be interesting to conduct a follow up poll.
Anecdotally, can't remember seeing any new complaints posted since I published the report. It had been a pretty hot topic over the previous years. Whether this means anything -- whether Sherline found and fixed a problem -- I can't say. I never heard from them on this.
I visited the Sherline plant in Vista, California some time prior to publishing my report. When I introduced myself, they apparently knew me from my forum posts, ("Oh,
You're David Clark!"). I believe that Sherline has a policy of reading, but not participating in various online forums. They could not have been more friendly and forthcoming -- gave me a great extensive tour of the place, showed me anything and everything I wished to see about their processes. I remain a dedicated, devoted, and enthusiastic user and advocate of Sherline Products.
