I got my 5C end mill sharpening fixture yesterday. I took it apart and cleaned all the cosmoline off, lubricated it lightly and reassembled. I put an end mill in a collet in the fixture and tightened it, and just set it on the mag chuck and enabled the chuck so it grips the fixture. I wanted to just feel how the indexing mechanism worked, if there was much play, etc. Mine clicks fairly positively and smoothly. However, my fixture has a little "shake" in it when I grip the collet block and apply force. I can see that it would have to have a certain amount of play. I'm curious if the other users of this fixture have noticed this side play in theirs, and if so, does it affect the end use?
