View Full Version : Which edge finder

I have a older Grizzly G1126 that jumps from 515 to 1400 RPM with nothing in between.
I'm looking for a good mechanical (preferably audible) edge finder that will work with these speed limits.

I see the Brown & Sharpe at good prices, but after doing many searches on the different forums, I'm not sure about my RPM limits. (??)

Any recommendations for an audible edge finder that's under $20, for drill/mill with the above speed limitations?

Thanks, and best regards,

Gary

I have a number of the Fisher ones and would highly recommend them. They list a max speed of 1500 depending on shank size:

I would definitely second the Fisher Machine edge finders. The quality is great. Order one from on another board and bought two others styles from him I liked it so much. He is one of the few people offering a quality 1/4 shank model (reduced shank).

According to Grizzly's manual you should have spindle speeds of 65, 130,220,480,926, and 1550 rpm. Sounds like you have a machine problem.

Not on his site but Fisher has one called the big jump. It is FANTASTIC! I think it is $17 +- It is my go to edgefinder.

No ... it's the older version of the G1126.
It has 105, 300, 390, 515, 1400, and 1820.
I like the higher top end, but the jump from 515 to 1400 ..... not so much. :(
May be time for VFD .........

Best regards,

Speed is not critical with an edge finder. Running faster may result in a crisper kickout but it is primarily personal preference. 1500 would not be too fast in my experience but I would stop there.
I once loaned my Starrett edgefinder to a co worker who put it a VMC spindle and turned it on manually. Since he did not enter a speed it started at the last speed command, 4600 rpm. Edge finder sounded like a shotgun blast. We found all the parts, put it back together and it's still good for .0002. Just lucky I guess.

Yes ... I'm starting to get a feel that the ubiquitous use of the term '1K' is not the max, and that the Fisher list speeds up to 1500 for shafts 1/2 and under, with the max of 1K for the 3/4".

I had tried to use a wiggler when I first bought this mill/drill (about 9 year ago) but got mixed results.
Over the years I found I wasn't using my mill/drill for much of anything that I couldn't just clamp the work piece in a 6" vise and use an end mill in a drill chuck, to get the results I needed.

But I recently added a Sino 3 axis DRO to it, and that has prompted me to look for a better way of edge detecting. In searching about on the different forums and YouTube videos ... I could never see anything other than the 1K recommendation .... hence the question.
And as you might imagine ...... I really appreciate the responses!!

Best regards,
