Was in the process of installing a Timney Trigger kit and got in over my head. Timney trigger is taller than the stock trigger, and requires some careful metal relief so the safety can engage. Did some Dremel work and took too much metal off leaving so it can fire when safety is engaged. OK...lesson learned . . have to buy new kit. My problem(s) (1) Safety is frozen in "Fire" position (2) Bolt is frozen in down and locked position and can't be raised to cock and remove.  Help!
