Spacing and Depths

Postby SmokieD » 12 Mar 2007 21:21

Awhile ago I was browsing this site and I came across a link to a page about spacing and depths on standard cylinders and I cores. I thought it was interesting but I didnt know what it meant. MACS,SHOULDER TO FIRST CUT,CENTER TO CENTER. All these terms left me scratching my head.

Ill post a Kwikset as an example



KWIKSET

SHOULDER TO FIRST CUT: .247''
CENTER TO CENTER: .150''

TITAN -- SHOULDER TO FIRST CUT: .097''
CENTER TO CENTER: .150''

MACS: 4

ROOT BOTTOM MASTER
DEPTH PINS PINS
----- ------ ------
# 1 .329 .172 .023
# 2 .306 .195 .046
# 3 .283 .218 .069
# 4 .260 .241 .092
# 5 .237 .264 .115
# 6 .214 .287 ***
# 7 .191 .310




If someone could give a description of what MAC, Root Depth, Bottom Pins, Master Pins, Shoulder to first cut, and Center to Center, all mean?

There are diffrent spacings on locks as there are pins. Most of the time there jsut diffrentiate the lock itself.

For example your kwickset haf 7 depths, while a shlage has nine.

For normal locks spacing is pretty standard. Now IC cores are meant for medium to large master key jobs, so you will find spacing very tight, forgive me i do not have the measurements for the pins, but in general each lock appropriates a given space and depth measurement according to it's function.

Things like the shoulder to the first cut are just a standard measuremeant taken so that each cut ont he key compliments it's given pin in the lock. They set these standards to keep key production and duplication standard and run of the mill.

If a lock is a puzzle, then its key is the complete picture
