2610 forum posts 312 photos | Chris If you bought a very cheap set you can improve the operation by lapping the probes into the ball joint, I don't use my similar very often but do not run it at high RPM when I do as the flailing stem stays in the deflected position. Emgee |

10668 forum posts 2415 photos | I think it's OK The stiffness is a compromise. Too loose and the wiggler might fly off, too stiff and it may not balance on the axis. My set is adjustable by slackening or tightening the holder. The ball at the chuck end doesn't need to be particularly true. Wigglers work by balancing around the spindles spinning axis, which means the free end is correct when the point is stable. The other, fixed, end doesn't matter. I rarely use my wiggler set! Instead a dress-pin (type with plastic ball on the end) in a blob of modelling clay is stuck to the end of the cutter or drill. Dave

325 forum posts 52 photos | Thanks for the replies, the free end that matters is interesting, because I can just see the shaft is not properly in the ball towards its centre, so its interesting that that does not matter. Edited By Chris Mate on 30/12/2021 18:30:49 |

10 forum posts | Chris Mate, have a look on You Tube, plenty of videos showing how to use it there. Using wiggler on a mill will find you some.

325 forum posts 52 photos | Trevor Johnson 1: I am fimiliar how they work, but now that I bought a set for the 1st time, My question was about what seems to me a manufacturing fault, it looks the stems at the ball that fits into the holder was not inserted in a hole that points to the centre of the ball, so when it turns it looks "off centre" at the ball. So apparently that does not effect the end result which is you get the tip stabilised and then that is the centre of the spindle, which you then aim at your mark on part, and if you marked correctly the hole drilled will be around the mark in my case the centre. |
