Distance between 9-9-9 & 10-10-10

[Olcaytug]

My bumpkeys were made of existing brass keys.

Please answer this:

What should be the thickness of the "something" the locksmith will put under the keyblank while cutting a 9-9-9 key in order to make it 10-10-10?

Please, I'm in a hurry: I was just going out but remembered this!

(Sorry to post the same message twice but I really need it)

Many ways to do it. One would be lifting the existing bump key up out of the vice a fraction and cutting further into it. Two would be to file further down than a 9 cut.

I don't quite get what you mean by:

I'll have the keys cut by a locksmith. It is advised that the locksmith should place a small piece of something between the stop on the key machine and the keyblank. What should be the thickness of that "something"?

It's called the fictional "10" cut because the idea is to put it the same distance below the 9 position as the 9 is below the 8 -- one space, in other words.

Anywhere in that GENERAL region (it's really a very vague notion; the real goal is just to get a little below the 9) is surely fine.

Thanks!!!

Then I'll make him put a few paper sheets(2 or 3) under the key blank!

I would actually really like to hear from anyone who has specifically tried bumping both ways -- with "bottom" cuts (9's or equivalent) and with "below bottom" cuts (10's or equivalent) -- and found the latter to work significantly better. Or who found the opposite, any data.

I simply use a piece of feeler gauge that is 1/2 of the manufacturers depth of cut graduations. So take schlage for instance with .015 between cuts, I would use a .007 or .008 piece of shim stock to give me what would be on a schlage key a 9 1/2 cut.

This is how I currently cut my bumpkeys on an ITL950. I have had more success this way than with the standard deepest cut bump key. Sometime back, I cut some bumpkeys for Chucklz so he could experiment with the same principal. If he still lurks around maybe he could chime in with his findings aslo.

As Zeke said it depends on what lock it is as a depth is differant depending on lock.

Oh and the spacer goes under the key in the vise not between the stop

Wouldn't it be easier just to cut a little deeper than putting paper under the key? Unless you are using a Multicode, but even then all you need to do is cut by micrometer.

[vector40]

Most code cutters aren't really set up to cut to nonexistent depths.

[Varjeal]

Actually, the ITL950 is perfectly set up to do so...it can be programmed temporarily to cut deeper or shallower in a few simple steps.

The HPC blitz's are also good for this as well. Since each cut is made by manually turning a lil' wheel, the user can deliberately over cut.

Not sure if the others can do such, but those two in particular are uniquely suited.
