I am going to make a bump key and am confused as to one aspect of it.

How do i know how low to cut the selected parts:

If the picture is not clear then i guess you could refer to them as the "mountains"

Thanks

It really depends on your key.
Alot of bumpkeys are cut to the '9' depth. So - a *guess* would be to file down to around the horizontal line, or above it.

Just remember... you want your peaks (mountains) to be nicely sloped. If they are too steep then the pin will not be able to jump up over it correctly.

I hope i'm making some sense... I've been up way to long today working... good night!

If I understand your question correctly, you don't touch the mountains, just the valleys.

General rule is half a cut deeper than the deepest cut for the particular lock.

I have details for most if you would like to email me

Apologies I somehow left out following.

Only part you file are the cuts. Correct placement of these are:

Shoulder to first cut.

Centre to centre for remainder.

You do not touch the material between cuts.

Rest as per previous reply.

"Valleys" are called cuts.
Slopes of the cuts are called ramps.
Ramp on head side of cut is called entry ramp.
Ramp on tip side of cut is called exit ramp.
Angle of ramp is called cut angle.

What I do with this key is to file all the valleys to the line and make the slopes little steep for making the pins jump over it. and this is what I suggest you to do.
