Hello All, This thread serves as a warning for those who are thinking about stringing their own crossbow 6 10 whatever.... USE THE TOOL THAT THEY RECOMMEND. I use a 6 mount Crank Machine (Progression II) and when i took the racquet off the machine after finishing the job... the 12 o'clock mount slightly cracked the frame... The only reason i tried to string w/o the tool is because i called HEAD and asked them if i could do it w/o the tool and they said i would be fine. LIES!! You are warned. Now i'm heading out to buy my customer a new Crossbow 6.
