five setups with an edge finder
but there are 6 that i know of or could remember
on the 5the segment i included 2
this video was made to instruct my students on the how to on "setups"
the general use and maintenance video will come later
with this video i tried a new editing style (video interacting with photos to try and get a better understanding)

I wish I'd had this when I was learning how to use one. I have one of those double-ended edge finders and unfortunately I'm self taught. It took more than a little scratching to figure out I was supposed to hold it by the center body and not the end.

Whoops.

Hi Elizabeth
thank you for your reply
I am trying to develop a style that a student can visualize and repeat when delivered in small chunks

We can also locate [via pointed edge finder] accurately scribed centers by setting the point in one axis of scribed line LIGHTLY, then move axis until the body and point measure concentric [by feel or micrometer] then the other and recording each position. Some use a fingernail to detect the offset; I use .003 feeler gauge. Small clean holes can be done the same way.
It's good to have a selection of edge finders. The .200 Ø are popular, but aren't ideal centering on larger shafts. .500 Ø, not having that neck work, until the amount chucked and remaining section won't reach the centerline of bar.
But all-told, I use a static dowel, or round body above flutes of an endmill nearly as often.

thank you for your reply
this video was made for my students to give them an idea of what they can do with an edge finder
there is a sixth use that i missed it was locating a round part vertically in a vice
toolmaker 51 thank you for your input I might use it in a more advanced video

Happy knowing somewhere, genuine vocational courses are still offered. I'd throttle whoever first decided it was no longer viable elective curriculum.
