Thanks gents, but there's always another lil curve ball with home grown solutions. Seems the indexer is so smooth on its end face that with the acrylic, or peek it's not possible to ensure zero rotational torque as the mill bit turns. Going to need to give it some teeth where it marries up against the inside of the handle or I'm going to have uneven spacing or flutes still.
So, not back to the drawing board per say but definitely another amendment pending, hehe.
Sadly I did bugger one of the peek testers and seriously wounded my emerald one before I saw the drifting. Only plastic, but 'twas all the acrylic I had. Need to order some now.
Benz, mad props for training next gen tradesmen sir. Sad as it is to see the good ones go, it's great to help them up along their way huh?
Haven't had that particularly bittersweet sadness in a long time unfortunately. All my guys these days would never leave, wish as I may that they might...
