Nice one, bonez!
I've got to agree with Shrub, though. I've been on this site a while now, and am still learning. I've been trading for six months, nearly, and every job I do has that tension of "What's going to be on the door."
However, I've not been stumped yet. I've not failed to get in yet. And I've never failed to complete a job. Both the locks I've drilled were full of epoxy, and beyond help.
Hence, I feel I can offer constructive advice and help out others. But I still don't chip in unless I *know* the answer, or I will mark the fact I'm not sure, YMMV, etc. so as to not mislead.
How can I know what I know? Because I read a lot on this site and elsewhere, but also because I go off and try things, I talk to other locksmiths, and I know various useful and intelligent people. That way, I have something new to add, and I'm not just re-typing other posts I've read.
Too many people now seem to be chipping in with something really useless or wrong. And that's bad.
