Audible (CLICK) Edge Detector ?
I've used the little edge detectors from Fisher Machine for a few years now.
If I take my time and bump up 5 tenths at a time on the little CNC mills I get pretty good results. Better than the machine itself. Good enough for rubber worm molds anyway. I've never used the audible ones. No, not an electronic thing, but a mechanical "click" when it breaks over. How good are they? Does the mechanism that makes it click have a negative impact on accuracy? Also, is Fisher still making edge finders? I tried to visit what I thought was their website and got a link farm page. I could have sworn I first bought them direct thru Ebay then from their site, but I couldn't find either. Just a few from third party seller. One more question. How does a ball on a rod type wiggler compare for accuracy to an edge finder? Seems to me that backing off and coming back in slowly to get your final result would be kind of tedious with one of those. My reason for even looking at them is because they kick so far back and up when they hit that damaging crashes would be virtually eliminated. |

I got one of the audible ones, it seems to work, and can be heard pretty clearly even when wearing ear protectors. I'm now using an electronic probe in most circumstances, but still keep the edge finder for when the probe won't fit. Jon |

I've only seen them in catalogs and the pictures have never been clear enough to show what does the clicking. The edge finder I like the best is a "Super Jump" edge finder. I think Flexbar sells 'em. I have several edge finders but the Super jump gets the most use because it is the most accurate and most easily visible. Eric |
