this picture should help, i like this one better.

but then again, i just use my finger... well i suppose if you are a 1 armed person then this would be a very handy tool... well then again you could pick it one handed with a rubber band attached to your thumb, huh...

all well, good thinking though!

One thing that I'm not quite getting from this conversation is how does having a weighted tension wrench help unless you have already opened the lock and know how much tension is the correct amount?

If the purpose for the weighted tension wrench is to allow a lockpicker with only 1 useable hand to pick then it has great utility.

But how will you know if the tension weight is correct?

Raimundo's idea with the rubber band is brilliantly simple and provides a lot of utility in that it would offer pulsed changes in tension which you could use with slow raking to really feel out the lock.

Another thing to point out here is that not all tension wrenches have 90 degree bends in them and that the weight needed to provide the same turning force (torque) goes up rapidly the more obtuse the angle in the tension wrench is.

LeeNo,

I think originally the concept of this conversation, was to introduce a way for new people and experienced people alike, to revisit the issue of what proper tension was, and how to identify security pins, what the tension wrench would be doing when setting a false set spool pin, things of that nature. Not to say that i'm trying to reinvent the wheel, or that Rai's idea isn't as viable, or anyone else's for that matter, that's not where i'm trying to.

Originally, I thought this might help explain tension better, using a constant weight at the end of the tension wrench helps the visual side of lockpicking by allowing the operator to see first had, that they are either using too little or too much tension, by noting that the weight they choose either isn't enough to hold pins up or is too much because every pin is binding.

Starting out with a single brass key blank, representing roughly light to moderate tension, and then adding a second brass key blank, the weight of the two blanks are felt in the stress of the tension wrench, which would hopefully indicate to a person, that that might be too much tension, depending solely on the lock. Another thing I took into consideration, is with just placing the tension wrench and allowing it to hang freely, how much did plug rotate, if at all. Depending on if there was any or alot of rotation with just the tension wrench in place would further help the operator decide if one key or more would be needed to provide the the appropriate amount of tension needed to turn the lock soley on the weight of the tension wrench once the lock is correctly picked.

I hope i'm not confusing anyone at this point.

Thanks. I had sort of drifted away from that. I was thinking that the idea was to introduce a tension wrench with some arbitrarily derived weight as a solution to the problem of "how much tension to use".

Experimenting with different weights and understanding how those weights effect the picking is a great instructional aid!
