To put you lot out of your misery, the rough profile of the bowl was ground with a spherical ball cutter used in a Ax flexible shaft (
https://www.axminstertools.com/heavy-du ... aft-910258) and it was very effective on such a hard wood:
- (348.57 KiB)
The final semi-spherical profile was shaped and smoothed using a small pneumatic Kirjes sanding drum thingie:
- (398.24 KiB)
The specialised sanding jobbies go from 80g, 150g and 320g so it was simply a case of fitting the appropriate one, giving the drum a squirt of air and jamming into the rough cut 'ole; the one on the bench has is the final one I used.
