Hi. Thanks to Archery Talk this forum option is now available.
I am going to be out of town for a few days and will then start posting and hanging out here.
My first project will be to show a history of how my product came to be.
I am turbonocknockguy now on this site. I have been a member of this site from just about its beginning. I used to post as Nick Snook if you are interested in researching me or my products.
If you just type in turbonock in the search box at the top of the page you can find out a lot about my products. you can find out a good deal by going to my website www.turbonockfactorystore.com or just click on the flashing turbonock avatar on my posts.
Well, I have to start somewhere.
My Dad Jim Snook had a small archery - gun shop in our basement in Middletown Pa. He started teaching me to shoot when I was 3. in 1951. my First torunament at age 5 . I won with arrows I made.
In the group photo I am on the front row right. The big guy behind me is my DAD!. He would let me experiment with my arrows and I was always trying to get better arrow flight. Everytime I tried something he would examine it and tell me why it would not work. He was also an aeronautical engineer and pilot. Everytime he was right. I learned a lot about the physics "playing" with arrows in my youth. I also hand loaded cartridges for hunting and learned how little it takes to change the performance of projectiles in flight. I learned that even though bullets have no feathers they are more presise when it comes to accuracy. The high rate of rotation the rifling in a gun barrel provides creates the accuracy. Arrows use a fairly low rate of rotation using vanes that spin the arrow using wind resistance. Most common arrows only rotate 2 times in 20 yds. The Quick Spin fletching products advertise three times faster which is 6 times in 20 yds ,but they tend to loose trajectory because of the method they use to cause more rotation. more wind resistance. The Turbonock was tested at the PSE Test Facility and in high speed video showed two revolutions in the first 5 feet of flight. That comes to 24 revolutions in 20 yds! What makes this happen is a small twist in the nock rather than a straight nock. I guess you could call it rifling for arrows?
Forty years after my childhood experiments with no success I was working in a mall in Mass. and was bored to tears. I started spinning a quarter on a table and had a DUH! moment. Why not mechanically spin the arrow just like rifling spins a bullet. I drew a sketch on a paper bag. A few weeks later when I was back in pa I hand carved the first "turbonock" experiment. i carved a twisted nock out of a piece of nylon and hand fletched some small pieces of turkey feather to the shaft. It worked. off a recurve bow. I wll try to find photos of the early experiments and post on the next visit.
