Hi , I've been a machinist for 38yrs, so I know how difficult off-hand tool grinding can be.

My apprentice years were with a microscope manufacturing company , where surface finish of all items was important. My "Tip "to finish off a radius forming tool is ..... turn up a short piece of soft material to Diameter required, leave it set in the lathe and add a coating of lapping paste, then run your roughed out tool bit up and down by hand ( with spindle running ) too polish in a perfect rad.

@Sawdoctor2 great tip - thanks!

3:35 - 3:58 was the best part of the video

@HeadShot360IN Thanks! I'm glad you enjoyed those 23 seconds out of an eight minute video where I mistakenly had a bad camera angle. I would recommend you not watch any of my other 100+ videos on machining, nor any future ones, for fear of a future bad camera angle.

Did you ever think to put your grinder on a bench

[saunixcomp]

@Maurice1469 No - do people put them on a bench? Of course I have... but this was when I ran my shop out of a Manhattan apartment. There was no such thing as room for a grinding bench.

@BoldUniverse Yup! I am an amateur. But you know what? That's how people learn. I love machining as a hobby and enjoy sharing what I have learned with others.

You have nice hands, but are we not supposed to see the tool you are sharpening ?

First time ever I added a clip to Ytube ..... ( and yes, it involved some tricky tool grinding ) .... its a vid of my day job , slotting an internal spline . ...... Hhmmmmm, ..have a look at " Internal spline cutting " ..... large Butler 32" slotter .

@BoldUniverse Professional douchebag!

@mykmykmykkk Never had a single complaint. It was a pre-war (e.g. pre-1940) building with solid walls. My noisiest piece of equipment was an air compressor, but it was a special quiet compressor.
