Should have some bigger, better magnets here tomorrow. A couple questions in the meantime:
1) Would it be a good idea to lightly polish the inside of the copper cup? Say with some fine scotch brite? Mine is kinda grimey.
2) Any suggestions for creating more of a snug fit for the needle hub on the spindle? I think mine will creep a bit as it over time as it contacts the stop. Thought about a tiny drop of blue loctite. But I don’t want to do anything that will make future removal impossible.
