I have been in Shanghai for several months. Back home in Los Angeles, I have the luxury of my Ektelon and Czech Tension stringers, but what to do while here? Before I left, bought a Hawk 12 on Craigslist and planned on using it. Unfortunately, "out of the box" the Hawk 12 was not usable. I couldn't get the gripper to work. I couldn't see using it for anything above 25 lbs of tension. Also, the head mounting system is not very sturdy and might allow the frame to deform while stringing the mains. So what I did was wrap a used racket overgrip around the string gripper to produce a tacky cylindrical gripping surface. Before dropping the weight, I wrap the string several times in a way that successive wraps underlap the previous ones. The string grips very nicely around the tacky surface and does not slip. I am still able to use the rotational ratcheting mechanism of the gripper drum to achieve a final level drop weight rod. To address the risk of frame deformation, I string 4 cross strings using Cyber Blue (I was thinking that the stiffer, the better) at 40 lbs. I remove those, position by position as necessary, as I approach while stringing the crosses. It takes about 45 minutes instead of the usual 30 with other stringers. With this stringer, I have been able to string Prince Synthetic Gut Original every 8-10 hours of play and I'm a happy camper. When I get back home, I plan on improving my Hawk with further mods. Another thought would be to fabricate a metal brace that you could attach to the frame that would prevent frame deformation and would remain on the frame during the whole stringing process.
