Updated Ferrule Dimensions

I've been fortunate to have shared a cabin with Alan Kube, Lee Koch and Don Hansen at SRG for several years.  I look forward to the dining table discussions almost as much as the official SRG presentations.

While I had a captive audience, I asked Alan Kube to take a look at the step down ferrule specifications I've been working on.  Alan has been using a set of modified Payne dimensions.  The dimensions were modified before he got them and he has modified them again based on his experience making and installing over 150 ferrules.  Alan is very good with numbers when it comes to engineering a gadget.  He sat there with no notes and told me what every measurement should be on a set of step downs from size 8 to 17.

Alan's step down dimensions are intended for ferrules made from drawn tubing.  The step is a full 2/64ths for all ferrule sizes to allow for a strong male transition in the shoulder of the ferrule.  If you downloaded the previous super Z version of the workbook from this blog, you can replace it with this new workbook that includes both super Z and step down dimensions.

By the way, Alan was honored with SRG Rodmaker of the Year at the gathering this year.  To be recognized by a group of your peers if very cool.  The award was very much deserved.  Alan's willingness to share the details of the craft with new makers like me helps build a foundation for even better rods and rodmakers in the future.  Congratulations Alan!
