I am once again attempting to make my first automatic. I have install the torsion spring in the blade and liner of the knife but the spring does not seem to give it enough torque. I tried putting more tension on the spring but it simply deformed. I am using a 3/8 od spring from knifekits. the blade is 4" long 3/16" thick. It is still heavy as I haven't yet ground the blade. Should I be using a heavier spring or is there some trick to installing the spring that I am missing.
Thanks
Steve
