Went to the hobby shop today hoping that I actually had a "long" adoapter that had been miss labelled. No such luck. We opened a new spinner and new adapter and they didn't work. Then I went to a friends shop and he cut of 1/8 at the 8-32 end. turns out we cut off all of the 8-32 threads with it. All 3 of them. My friend says he thinks he has a 2 inch True turn spinner and nut at home that will work for me. I find out tomorrow morning.
