Hi Levi!
Yes, it has been a hectic week. I am happy to say our last email generated about 200 orders, which we have shipped same day they were received. I hope to catch up to the phone and emails this weekend.
With respect to your question, I am amazed that there was a problem. These bushings were made (twice, first time had a small problem) to fit the perfect fit and were made just for Exotics, because I don't like to force customers to use the B mandrel.
However, I have just checked several sets of bushings and find that one bushing is incorrect.
If you try the set on a new set of tubes, three of them fit. ONE does not. The shoulder on the bushing is less than one thousandth of an inch too large. While I will be happy to replace yours (and I will be modifying the ones I have so they are correct when shipped), you CAN put it on your mandrel and sand it down a thousandth and the problem will be solved.
I will try it tonight and let you know how long and what grit sandpaper works best.
Sorry for the inconvenience!!! (I did test the first sets, they worked fine)
