For anyone who has not seen this the process is to turn a toroid (from beech in this case) with the appropriate cross section which is then cut radially into 3, of which this is one segment. Then use a jig to hold the piece on a chuck to turn the ends. This gives tapered but round cross section ends (unlike an actual banana where the 4/5 sided section persists towards the ends) so some further shaping is needed - in my case using a small diameter (50mm) drum sander mounted on the lathe. Note that the drum sander is also useful to smooth the inevitable rough inner edge on the detached toroid.
