When you guys read the manual Framon has concerning Kwikset spacing, or at least the one I have from 2000, keep in mind if you go from the 1 cut to a 5 cut for example or lower, the spacing recomended by Framon is off, IF YOU USE A WHEEL FROM HOME DEPOT, for 25 bucks that has a (more rounded cutting edge or others with a round edge).
The Framon book says all bottom flat cuts (where the pin rides) are .050" wide. When using the standard cutting wheel from HOME DEPOT or others that are rounded on the cutting edge on your duplicater you should subtract from the .050" on the deepest cut, the deeper you go with the next cut being next door while staying within MACS by about about .003 to .004 per depth.
If you duplicate a key by code using the book by Framon as of 2000 with the standard cutter on the Framon with the Home Depot cutting wheel on the duplicater, the upper cut, the 1 cut, will not line up with the bottom pin because the deep cut, the 4 cut in this example, is too wide causing the 1 cut to ride on the slope of the 4 cut making the short 1 cut pin ride low on the 4 cut slope. This can be complicated do to the fact that Black and Decker, the owner of Kwikset puts out other products that are not as accurate in spacing, plus ALL the other locks like 3 or 4 overseas locks that use this keyway or even a few in the states, this happened because this keyway is common here.
If you shorten the deep cuts from .050" wide as recomended in the 2000 Framon manual when they come next to a shallow cut using the STANDARD cutting wheel Framon puts out to .035" or .040" on the deep cut especially when using LAB pins with the more pointed bottom tip that comes in contact with the key, it will solve the problem where your duplicates dont work even though your originals cut on the Framon do work.
Take the plug out of a lock and with it pinned up to specs, insert the duplicate key and the key cut on the Framon to notice the problem with the spacing specs Framon has in their 2000 book. If this has already been talked about, and/or takin' care of, sorry.!
It all boils down to the rounded aftermarket cutting wheels cutting off the upper and lower ramps on the 1 cut next to the 4 cut or deeper during duplication because Framon in the book I have doesn't compensate for it in their saying all depth cuts should be .050" wide on Kwikset spacing. Think about it. A deep .050" cut will effect a shallow cut. This seems easy to notice but it can cause problems when you are working late and tired..
Framon, please take this into accountif you already have'nt.
BTW, I love Framon machines.
