True Turn nuts and jams
Has anyone ever counterbore a propeller so the jam nut fits. I am using a Saito 91 and it has a short shaft for the spinner the kit came with. The Ture Turn calls for 1/2 inch hole at a depth of 3/8 inches.

RE: True Turn nuts and jams
I have a Magnum 91 and my Tru Turn spinner would bottom out before seating against the backplate. I talked to Tru Turn on the phone and they were very helpful. Except that the replacement they sent me also bottomed out. I simply cannot make it fit. My problem sounds differant from yours tho. I just gave up and flew without it.

Hi Bob
True Turn gave me B&B's number and have been calling for a week but no answer. Any ideas if they are still in business?? Thanks

Good Morning Richard:
I have no clue regarding B&B's status, but it doesn't sound good. I purchased my drill bits several years ago. Keep trying, good luck!

Check Fox products (the engine makers), they have crankshaft extensions. http://www.foxmanufacturing.com/inde...ort=20a&page=3

RE: True Turn nuts and jams
Good plan on the prop shaft extensions, But i do think a Saito91 is 7mm. Fox does make three different prop reamers including one that goes from 10mm to 12mm which is probably what you need to counterbore with. I never did like the stepped down drill bits have always been paranoid about it catching in the prop and sending it spinning into my hand.
