Jean-Marc now has a more appropriate (uncut) spinner for his PC-21.
I added one to my prop order. If you’d like pictures or measurements, let me know.

‘We could offer you our 4.5” Ultimate shape spinner

Product Listing -

We would request you send your prop to us as we do not have that prop or program. We will not know if this spinner could be slotted to accommodate the prop until the prop arrives. Our spinners have to keep 50% of it’s meat and without a the prop or program there is no way to verify this. Yes we can add the light backplate in the 4.5” and we can ream it 10mm for the K45tp. Please let me know if you are interested. ‘
