bump key pick?

[bpc293]

i am grinding down a hacksaw blade and i was going to make a sawtooth rake. i put it up next to one of my 6 pin medeco cylinders. i marked the blade where each pin would sit then next to a 5 pin kwickset the spacing was the same. if i cut the rake just like a bump key would i get the same affect but by pulling it out quick. or is that just plain silly thinking.

[n2oah]

That's silly. The transfer of energy won't be very effeicent at all.

[bpc293]

ok i'll go back to copying one i seen online

[undeadspacehippie]

I have a rake that is almost like a bump key - the cuts that is. It works wonders on the master no 3's, put it in once, apply pressure on tension wrench and it opens.

[bpc293]

ah screw it its just a hacksaw blade i'll make it

[bpc293]

yea no i have this fear something is going to break in my building and i am not going to be able to find a saw.

[Gundanium]

Yeah it wouldn't be the best idea to make that, you'd probably have to implement a tension wrench because your hacksaw blade wouldn't last too long as just a thin piece of metal getting slammed on, better off using a tension wrench and a raking tool.

[bpc293]

i'm sorry i new i would have to use a tension wrench. i should of put that in there.

Well the important thing to remember about bumpkeys is that their spacing isn't really the active factor in their effectiveness. Yes, the spacing does have to be fairly precise so that they lightly touch the pins, thereby transferring energy. But the spacing itself doesn't lift the pins to the shear line. So even if you perfectly modeled a pick after a bump key, it wouldn't be any more effective than a normal rake.

I think you mean a saw-toothed rake.

does anyone know the best file to make a bump key

i want to make a bump key for american locks series 5200. what size and type of file should i go about using

[digital_blue]

Square files work great. Type of file seems to matter less.

He said medeco.. i didn;t know you could bump them, if sombody invented a bump key for one of them medeco would sh*t a brick lol

It has, in fact, been done. Zeke's got a vid of it in the advanced forums, I think. But... that's about as far as we go in the public forums on the matter. Yes it can be done, but no, we can't say how.

Sorry to be a stickler, but if bumping Medecos isn't advanced material, I don't know what is.

Haha no worries DB thats actually surprising, cool to know anyway continue with discussion.
