Cut depths

[TheSnakey]

could someone translate this for me i dont understand the measurements are they thousanths of an inch?


# 0 .320 .150
# 1 .305 .165
# 2 .290 .180 .030
# 3 .275 .195 .045
# 4 .260 .210 .060
# 5 .245 .225 .075
# 6 .230 .240 .090
# 7 .215 .355 .105
# 8 .200 .370 .120
# 9 .185 .385 .135

if it is inchs could you maybe tell me the depths in mm or cm
thank you

Well, without knowing a thing about the lock type whose pin cuts you are trying to decode, I don't know if we can help you much, but yeah those are almost certainly measurements in inches. The part that confuses me is how you have three values for some of those cuts. What type of lock is this?

As for converting them, that's easy, you can use google to do it. Here's an example:

you can ask google any question like that and it will do the conversion for you, part of their calculator feature.

Snakey,
Without context, those numbers might as well be baseball statistics... not sure where you nabbed those from, but here's a screenshot from the original source: (I have added some notes to explain what's what.) This type of table is called a depth and space chart.




Converting these numbers to mm or cm will not help you. These numbers are established when pinning locks. I don't believe locksmiths often reach into their pin kit for a 3mm bottom pin.

hope this explained things for you,

I'm trying to cut keys for c4 barrels. I would like to know how deep each cut in the code is from 0-9.

Well, if you examine the information that squelchtone posted, this should be pretty easy to figure. Assuming that a zero depth is the same height as an uncut blank for that position, you know that the root depth is .320", the height of the key blade. Continuing in that direction, a 1-cut has a root depth of .305". Take the difference between these two and you get .015", which appears to be the difference in depth per each cut increment. In fact, the root depth figures for the subsequent cuts bears this out exactly — each cut is .015" deeper than the previous one.

Hope that helps.

You've gotta stop calling them barrels mate. They're either cylinders, plugs, or cores. Please use the proper terminology. And are you trying to make bump keys still? If so, its only fun for about 5 minutes, you should concentrate more on picking locks. I know in a previous post you said to someone not to assume you're trying to break in somewhere when you asked for master keys, so please clear the air here and tell us just what the heck you're trying to actually accomplish. Its hard to help someone if we only get bits and pieces of whatever project you're working on.

Thanks

im trying to cut my front door key why cant someone just give me the cut depths without going threw all this shit

im trying to cut my front door key

In that case, the "Root Depth" in the table above should give you all you need to decode your existing key and make a copy.

I'm a bit confused, though: if you're trying to cut a key for your own front door, why would you require a depth and spacing guide? (Your duplicate should be the same dimensions as the original, no?)

As MacGyver101 wrote, the root depths in that chart is all you will need.

You have two options.

1. take blank key and your house key and put them in a vise. grab a file and start filing until the keys are identical. Mark your house key with Sharpie before you begin so that you can tell when you are accidentally filing your house key down, which will eventually make that key stop working.

2. grab a blank and mark the centers of each cut based on the shoulder to center of 1st cut distance and then mark the remaining cut centers based on the 1st to nth cut distance. now start filing 1 cut at a time and taking measurements to see when your root depth matches the root depth of your house key. repeat until all cuts are done. even out any peaks and valleys so they aren't too jagged and mis-shapen.


you originally asked about converting to mm.. if you're using a ruler to do this task, then you fail. to do this job with any accuracy, you'll have to do step 1, or if you're really set on making this key from measurements, then you'll need a digital caliper to measure the root depths accurately.




I consider this topic fully explained and the previous posts and charts provided are all you need to do this job. In lieu of your road apples comment, good luck, you will receive no further help from me regarding this topic.

Mark your house key with Sharpie before you begin so that you can tell when you are accidentally filing your house key down . . .

That's an excellent tip: I hadn't thought of that before.

Thanks man, I'm sure I learned it from one of the lp101 elders at one point or another.

btw.. congrats on your 500th post =)
