Stringer exploded

[dainova]

Hi, my older Gamma broken during stringing Hammer with 110 head:
BOLT as indicated on pic broken in two where it has cut for clutch. I know that mounting racket is delicate task and I hope that exactly what I did, no extra pressure, not too tight, etc..
Anybody can tell what can be wrong, why racket went up? Clamp with bolt litterally exloded flying 10 meters, spent some time to find it. It was after tieing Mains. And it broken at the Head mounting pier. Generally I think that racket changed a shape a lot, though I didn't found any cracks, etc... Probably this how it works for 110 heads comparing with MSize.
Also question: do I need during mounting to rise that plastic INSERT all the way up to the grommet hole (it can be moved on 2 pins), that probably will provide more stability and eliminate racket's movement up?? Probably it was my mistake.. Same thing with side pressure plates ?

Will try to find that bolt in GammaSport store..

Will appreciate all feedback.
Thanks a bunch.

P.S. BTW I hope that on this machine I should read tension from that side of the weight which is closer to rachet (or far on the picture, where there is smaller weight with fixing knob). It's obviouse but who knows... I don't have a manual.

You can post a question about this to GammaTech on the TW msg. boards. You also might do a search on there and find their phone or email contact info. On your other questions; you read the tension setting from where the bottom of the weight meets the arm. If the adapters are adjustable, they should be raised as close to the grommets as possible to give the frame maximum support. Some machines have a variety of adapters that can be interchanged depending on the frame.
