Bump Key HAMMERS--please post ideas, designs, pics, info etc

Bump keys and lock bumping finally have their own area. Discuss making bump keys, proper bumping techniques, and countermeasures here.

My hammer, by the way: http://berkeleyhigh.org/provinggrounds/ ... hammer.jpg

Two metal rulers (of different brand and flex, actually, but whatever), duct-taped back to back, with a small chunk of the wood from my practice board on one end, wrapped with quite a bit of duct tape, on the theory that it would add a bit of cushion.

I've found holding it about in the middle with a small-to-medium-length but decisive stroke works best for most stuff. For pull-back bumping, I hold at the end and give a long swing. (My fingahs!)

Still tinkering. Wish I had more locks here. This is TOO cool.

I have not, by the way, found that differences in pin number (well, insofar as 5 and 6 are different) matters much.

Just ask around your local lockeries, fella :-D You may get rebuffed once or twice, but I can't imagine that nobody in town will be willing to perform what is essentially a straightforward code cut.

Current status: I've bumped both of my test cylinders to death :oops: Neither really wants to open, although I can still pull-back bump the lousy one.

I'm really curious whether anyone else has had good results with pull-back as well.

Vector,

I have been able to "pull back" bump some low security locks such as schlage 5 and 6 pin standard C keyway locks but I find that if there are a couple of 9 bittings that I have more luck with a 10 cut key. I have also found that this method seems to be harder on the locks themselves. Not only from a pin and spring stand point, but from a lock face stand point.

Do you mean that you found minimal-motion to work better on locks with 10 pins?

Thanks n2oah.... My Tomahawk will be here by the end of next week so there really is no may be getting to that one.

vector,

Yes I find that minimal movement bumping works best on locks with higher tolerances such as the evva GPI lock I wrote about in my bumpkey article. I have not tried bumping any dimple locks so I cannot comment on them as to the best method. If you are having better success with the pull back method then I would say keep working with it. With bumping it seems so far that everyone has their own technique.
