I made a simple tapering jig (side profile) - no laminations, just one piece of clear hickory.
I like these nocks as they are fast to make (I use a small rectangular rasp from lee valley that is just the right width so I never have to measure). I put two nocks in so I never need a fancy stringer, just a larger bow string. Sometimes I put three nocks in to vary the poundage for people who are just starting out. There are fancier bows for sure, but I am going for ultra efficient design on this one.
