I am posting this so others here to know what to expect should they decide to install Sperzel locking tuners. This installation is not for everyone and I think if I had attempted this on a Gibson, I would have become physically ill after the first set-back 
Victim: Epiphone Les Paul Plain Top
Had to enlarge torgue screw hole for the larger torgue peg of the Sperzels. Used the drill bit specified in the instructions. Once I did this, I noticed the collar or sleeve that secures the tuner, was just a hair to large in diameter to fit through the front of the peg hole. It could slip though from behind the head stock easily, so I knew I to remove a very small amount of wood from the front of the holes.
Used a dremel tool and the cutting bit (similar to a rotozip) Removed just enogh material for the collar to pass through the hole without using force. This was easier than it sounds. Once I did the first one, the rest went real fast.
Once I had installed the first three, for the low-e, a and d, when I noticed that the tuners had to be turned opposite directions to increase or decrease tension. Electing not to drill new holes, I installed the other three tuners for the remaining strings. I guess I will get used to tuning backwards
The tuning seems solid, so I don't think the backwards installation is causing any issues at this time.
At this point I believe it was worth the trouble as tuning seems to be liquid smooth now. This particular gutiar had a defect in the Grover tuner for the D string, and had some slop in it. I actually went and ordered a second set for my EPI Standard Les Paul. If anything is different with that install I will post a followup.
