Round a steel edge question

[MikeInOr]

No confusion at all.

Edge, end, inside a pocket, they work wherever you use them.

Unless your confusing them radiused endmills?

I have a set of corner rounding endmills with 3 different radius. I haven't tried them yet.

Unfortunately the OP didn't list a mill as a machine he has access to.

Chuck them in a hand drill.

Since I can’t use smileys I’ll note that was a joke.

Don't necessarilly need a mill. Chuck the endmill in the lathe chuck and clamp the part to the cross slide.

I decided to try a variation of the filing button, here's an overview.

The part to be rounded is 3/4" wide with 1/4-24 holes, found 3/4" OD washers with 3/16" holes, drilled the holes out to 1/4". Bolted the washers, marked arcs and cut off the corners on the bandsaw. Ground the high spots with the bench grinder. Hardened the washers with a MAP torch and water quench. Filed the piece around the washers, finished with 400 grit in the P-C sander. The result is good 'nuff for this project.

A few details:

1) Center drilled a piece of 3/4" stock as a guide and drilled the washers for a close fit.





2) Marked the cut lines with a Sharpie.




3) Cut the fat with the bandsaw.



4) Bench grinder, filed and sanded.




There's a bonus in this approach for me; after filing, I've cancelled my gym membership, filing is far more work, and vastly more rewarding.
