Host the photo on a file server (photobucket, whatever) and then use the img tags to post it. eg.

without any spaces in it.

This is the home made 999 key

I also had one machine coded to 99999(yale key) but still no luck

I got a set of Yale bump keys from Souber, to try them out. But they said don't use directly (the bumping eventually wears out the leading face), get a good copy made (double-shoulder, original or steel blank) and use those.

Now I don't have and am not likely to have a key cutting machine. And all the key cutters I've tried around here seem to be pretty sloppy.

I've wondered if I can jury-rig a Dremel to copy a key; but I very much doubt it. When I get a moment, I'll probably knuckle down to it and file myself some good copies.

Just don't put the spaces in.

Looks like youve taken too much material off the shoulder and tip but it could just be the way your hitting it, ive not had much success but plan on trying it again after reading raimondos guide, it appears its all in how you hit it, i was useing a soft mallet but make a proper tomohawk and get the technique down.

[chrisjc33]

I have taken about 0.5-0.8mm off the shoulder and tip but can only set 3 pins at most. Good job there not 6 pins
i have even tried a little song(hit me with your tomohawk hit me hit me hit me slowly hit me quick.........)sorry about that

[Shrub]

Sorry it just looked like youve taken too much off, those measurements sound fine,

Ive not gone into it properly yet so im sorry but thats my knowledge on them gone now, it could be the wrong tension because your tune must certainly work although if it was me by the end of the tune each hit would be getting harder and hared

ive had sum luck with bump keys but not a great deal,especialy the cylinders with spool pins etc any ideas on how to bump them???

[roemer]

to open a lock with a bump-key gives a great feeling, more than picking.
The speed is mystrious

[roemer]

The key is softer than the lock, so if your key is for the eye not oke bump it several times hard.
After this bump not too hard and push/turn the key very soft.
You must hear the pins clicking.
At this moment I've problems with opening a cisa lock with the bump method. easy is the nemef, evva , corbin cilinders ect.( locks from the netherlands)

I made a 999 yale bumper in about 15 minutes using a small file from the pound shop. I attempted to use on a standard yale 5 pin door lock and nearly shit my pants when it opened with 3 strikes from a wooden spoon. The thoery of its great but feel its down to luck more than anything as you could sit there wacking the bloody thing for ages which only ends up denting the lock face its self. Must say the feeling of doing it is fantastic.
