Not my idea, just my take on it.
I had a few 3mm diameter parts which required hemispherical ends and remembered seeing a boring head used for radius turning.
My boring head sees regular use so permanently or even semi-permanently fixing it to something else isn't an option.
I pulled a 1" parallel shank OD to internal MT2 adapter off the tool rack, dug through the bearing drawer for a couple of 1" ID bearings, profiled a couple of bearing mounts and a connecting plate from some ally plate offcuts, drilled, tapped, added some locktite and a couple of bolts and came up with this.
I need to make a cutter seat with the cutting point at the centre of rotation for the bar mount but it works very well using a double sided triangular cutter.
My boring head is still my boring head but has an extra use ;-)
The first photo shows it assembled on the lathe, the second photo is a titanium bolt handle I made with the cutter.
