I took my TT trigger out of the Dagger, and opened it up to see what makes it tick. What I discovered was the outer edges of the string slots are machined square as you can see in the 2nd pic.
When the string is cocked, it’s guided into the string slots, and has to hit the front of the safety at the rear of the housing. This sets off a chain of events - this action moves the safety rearward and puts it on “safe”. This also moves the sear and allows the claws to move up and lock into position and hold the string behind it.
The issue is two fold - first the string has to go all the way back and there’s only about a 1/16” difference between the front of the safety and the back of the housing (last pic). While pulling the cocking rope back against the 220# limbs, and with the hooks on the outside of the rail, there’s little chance to keep from pulling the string past the front of the safety and wrapping around the outer edges at the back of the string slots as noted awhile back by Tnmnts.
I’m not capable of stopping my pull within that 1/16” margin so the string is going to whack the back of the slot and the cocking force will continue to pull the string around those outer slot edges. I do have a RSD cocker that I could use to stop any over travel from cocking, but I’d rather use the cocking rope.
So I’ve ordered some Mitchel’s 1/8” wide abrasive tape and I hope I can round off those outer slot edges on both sides slightly.
My latch edges are rounded and really smooth so they’re not doing any harm to the serving. It would be interesting to see if anyone that has a TT trigger is experiencing the same fraying issue.
