Five and a half hours to string my first racket. Actual stringing time was probably only a half hour, but all the mistakes and re-reading the "instructions" and insane stuff like taking 15 minutes to tie off my first knot when it took only 10 seconds to tie off the final just added to the frustration. I also had to pull out 2 strings to widen a grommet for the shared hole tie off which took me at least 15 minutes more as I didn't want to damage the grommet if I could help it. I was using 16 gauge, which at times felt like I was trying to bend cable wire. I did choose a complicated one string ATW modified box pattern and it did take me several looks at the racket I had with this pattern to reverse engineer and copy the path the string should take. That and the string tangling from the coil memory had me pulling out string and redoing them more than once. I had also hurt my back the day before, so sitting hurt, and standing hurt. (perfect storm) I wouldn't recommend trying to string your first racket with any type of back strain. I was lucky I could lift the machine to put it back when I was though. The fixed clamps on my Alpha Pioneer worked great, and I also used a starting clamp on the outside of the frame a couple times, so was glad I had one. The rotational gripper gave me a lot of trouble in the beginning which added another half hour to the equation. I finally by trial and several errors loaded the string the *opposite* of how it was described in the pamphlet and then I was able to tension the string. Needless to say the air was occasionally peppered with expletives, especially during the cross weaving, but eventually before the sun set I did finish the job. Lets see, 5 and 1/2 hours would be what, 2 bucks an hour? My finger nails were trashed and fingers themselves sore, but today not so bad. But I did it! And now that it's done, it's a beautiful thing. It looks ultra clean on the outside of the frame with only one overlapped string on the head between 7 and 9. I feel like I accomplished something significant, even though it only matters to me. I wanted to see if I could replicate that pattern and I did. I'm sure the next time I can cut the time down measurably, and if I were to use a two piece pattern, it should be much faster/easier as well. I can't wait to try it again.
