Whats wrong with this bump key?

That sounds like a better way to do it. Thanks I'll use that.

Yes, i think it is the shoulder area i have messed up. The lock is old and not the best either, sometimes it sticks with the original key!

Thanks for the comments, i will have another crack with a better quality lock when i get one.

Regarding tension while bumping, do you use a light tension then hit the key? or a heavy tension. If it has spools i would think you could only apply a light tension, or to you apply tension immediately after you have bumped???

Cheers
