  1. Nice job picking that old corbin mortise cylinder. BTW he replaced the original spring cover strip with 5 medeco cap screws. They do fit very nicely in the real world. I have done that my self for several customers. However…even when pinning the first 5 chambers the sixth should be capped as well so as to prevent dirt from getting in there.

  2. I think I've got a lock with the same key way.  Did they originally come stock with the 2 ball bearings?
    I've also got some stuff i'd love to send you (Challenge lock and a padlock that does not have the pin holes drilled)

  3. Bill, If youre ok with it, put me on the list for one of the giveaway challenge locks. I really want to try my hand at one since I haven't got my hands on anything localy bought that I cant crack. TIA 

  4. Could anyone answer this question for me? I hear it brought up a bit in Bill's videos and i was just curious but what exactly makes an Assa pin special and how can you tell that it's an Assa pin?

  5. Bill, too bad you didn't look in the shell. I tapped 2 pin chambers all the way thru to the shear line.  Put a LAB serrated upside down to catch all the threads, and the homemade is something I made and put it in to catch all the threads as well.  I made it from a plain ASSA driver. Chucked it up in my Rotozip and used a couple of files to shape it. The ASSA pin you called a Christmas tree is the old ASSA spool. Grooved on one end only. The new ASSA spools are a different design and are grooved on both ends. The old spool is no longer available anywhere. I have a few. They were replaced with the new style I believe in 1988 or so.

    The Corbin is as I got it on Ebay as far as the bottom pins. They are original and untouched.   I think in 1902  and for years they used balls because the brass was so soft that the pins wore badly. In the 60's when harder brass was available, they used ball bearings in the first 2 chambers only.  Now, they don't use any as far a I know.

    Thanks for taking on my first challenge lock. I am working on another.

  6. Since no one seems to be brave enough, I will step foward take on this new challege lock! Let me know, Bill, if you still have it.

  7. Shame he took the original chamber cap off. I'd say that is a 60's lock.
    Very nice pinning, were the upper chambers of 1,3 & 5 thread??
