Hi All,
I'm trying to pick a Corbin Russwin CO-88 six pin tumbler lock and I would like to use top of the keyway tension. I can rake it and can SPP it using bottom of the keyway tension but I seem to have problems SPP with top of the keyway tension approach. I know it's just me but it's not clicking (pun intended) together. I'm using moderate tension but tried to ease off but to no avail. Anything I need to consider?
