I cannot remember exactly when this transition took place. The heli-coil become damaged from over-tightening of the thumb screws. Tighten them too tight and the heli-coil compresses, kind of like a Chinese finger trap and then when trying to unscrew the thumb screw it just gets tighter and usually results in stripped threads and damaged heli-coils. The Heli-coil takes a special tool that is included in the price of the kit so the tool and several heli-coils goes for $110.00. It would be nye impossible to replace a heli-coil without the aid of this little tool. When techs take their training and we are required to buy all of our little gadjets to work on the machines, we get a sizeable sum wrapped up in tools....just another reason why it seems a tech call can be expensive. You just got a small taste of it with this little gadjet. A person could replace the X-carriage with the new improved steel insert one for not a great deal more, altho you need to be mechanically inclined to do this as there are important adjustments to get the roller guides set right.
