Corbin

I'm sorry his pins were on the top of the bottom pins. Probably is construction or 3 in 1 keying there. The locks I mentioned actually had the pins under the bottom pin directly in contact with the key.

Sorry all,
did not mean to be snippy.
The ballls work on other locks too. On some (unfortunatly) the pins need to be filed down. Too bad BEST does'nt have them. These pins wear quicker than the Corbin.

drill to the right side of the figure eight (be careful not to hit the cyl) if the core is the only thing you want out of the lock.

If you're aiming to drill the control lug, it's on the left.

Oh, and I'm in for a wow. I don't think anyone meant that you were being snippy, mikeg. Those "wows" are genuine in the traditional sense of the word - expressing sincere amazement, and in this case appreciation, for a concise informative post as your introduction.

Welcome.

Yes it is. Turn right or pick right, lug is on the left. Post edited. Thanks for catching that one.

I took apart an older Corbin 5-pin cylinder in a mortise lockset. The lockset has the CO-7/1001EN keyway. The cylinder is marked "CORBIN" in a oval on the front.

I noted the following things which may be useful to know:

- each of the 5 pin stacks contained a spool driver to resist picking.
- the front two (2) pin stacks have a ball bearing, with a shorter pin above it, to reduce wear on the key. This is not part of a masterkey system.
- picking was accomplished by raking; holding all the pins to the top with hard tension and then scrubbing the tumblers while releasing the tension slowing.
- because all five (5) stack had spool drivers, attempts to pick the individual pins were unsuccessful.
- the pins were .116 inches wide. The ball bearings were .110 wide.
- once disassembled and viewed from the top, the pin holes are slightly out of alignment--indicating that the cylinder, despite being of high quality, suffers from mass production defects which will permit picking.

This cylinder will now become my "high security" practice lock.

Another resurrection. This thread is 10 months old.

I guess I could have started a new thread--but why not keep all the identical topic information in the same place. Besides--a major complaint people always get directed at them is: 'why didn't you search that topic?'

Don't get me wrong, you did the right thing

It's just that there is so many resurrections going on lately, I was just commenting on another one. Keep up the good work!

Seriously. You're right, it's better than a noob making a whole new thread.
