I have a 2 inch Dave Brown spinner that I was planning to use on my Bonanza. I have the 1/4 28 short adapter nut, also made by Dave Brown. But the nut is so long, it hits the spinner and the spinner can't go back to the back plate. I'm using an OS Max 50 and I was hoping to use a 11X7 MA or APC. The prop doesn't interfere with the spinner at all.
I don't understand why Dave Brown would sell an adapter nut that doesn't work with his own spinners. Are there other brands that are shorter ?
