My new mantra!   I finished my die spring shocks last week ......... and cut them up into pieces today.  That's right, I cut them up.  I wasn't convinced it was the best design since the spring was non removable as I built it. 
 
Along with not having the spring removable I didn't like the size of the bushings.  After getting in touch with other builders and pilots who use this type of shock, I redesigned the shock to allow for disassembly.  Tonight after cutting the above finished shock apart, I started building a new set using the redesign below.  Stay tuned!
