Lathe "work truing" tool

[Canobi]

This is one of those very handy tools you eventually use all the time, and it's very simple to make:



I cobbled this tool together from items I had on hand, most of which is scrap I've salvaged from here n there so cost me time only, which wasn't very long.

I considered a press fit for the bearings but decided to bolt them in place as it to give it more flexibility, I'm fixing up a mill I got recently and it can also be used as an edge finder.

Job was simple, face, turn to size, drill, tap (M6 x 15), champfer, flip round, trim to length, repeat first four steps.

In this case though, it was a bit large for my small quick change toopost holder:



It held it very tightly though, so left it where it was and tried something new by doing a bit of light milling on the lathe. A 10mm two flute stub end mill took care of the cutting and just judged the cut depth by feel and eye, which went well all considered:



I then cleaned up the edges? flipped it round and it was a perfect fit:



For those that don't know how this kind of tool works on a lathe, here is a short demonstration video I made:
