Weve seen Schlage C key blanks with variations of up to 15 thousandths of an inch (.015)
between top and bottom shoulder positions between keys taken from the same box. It happens
more often than you think. The solution? Dont bottom shoulder gauge your keys anymore.
Cutter Stalls Out
There are six possible causes for this problem.
1.
You are cutting keys from Tip-to-Bow. This one can fool you if youre not careful. Cutting
keys from tip to bow will work when you cut only shallow keyssometimes a shop can cut keys
all day long and never hit upon a key with a deep cut. You think everything is O.K. when all of a
sudden your cutter stops dead halfway along the key. The problem? The deep cut put the cutter into
the key past the cutter tooth area on the left side of the cutteryou just reinvented the disk brake!
SOLUTIONALWAYS CUT FROM BOW-TO-TIP.
2.
Oil on the belt and pulleys. Clean the pulleys with safety solvent and install a new drive
belt.
3.
Left-hand nut securing the cutter wheel isnt tight.
4.
Belt tension needs to be increase and/or replaced the drive belt.
5.
Youre in your service vehicle. Youre Redi-Line generator needs repair, or your wiring
needs replacing (usually from the battery to the Redi-Line), or your battery is weak. Another possibility
is that youve been using a power converter and it is marginal.
6.
Your cutter wheel is really dull.
Stylus Shaves Material Off Key
The situation is caused by the fact that the cutter wheel is made to a sharp point and therefore to cut
keys accurately the stylus must also be made with a sharp edge. A key blank dragged across a sharp
edged stylus has no choice but to scrape material from the key blank. The solution is to lightly
blunt the sharp edge of the stylus. This has to be done carefully because if the edge of the stylus
is blunted to much you will narrow the width of the pin seat somewhere in the middleif the stylus
is sharp it will scrape the key to much, if the stylus is blunted to much it will produce a duplicate
key with a slightly narrower pin seat area.
If youre going to cut more than 5 or 10 duplicates off one key we recommend that you make first
generation keys and then make additional duplicates off of them. For example if you had to make
50 duplicates off the same key you should make 5 or 10 first duplicates and make 5 or 10 duplicates
off of each of them. This is a classic example of why your key machine should always be maintained
in perfect depth and space adjustment.
Cutter Leaves Ridges on Cut Key
This situation is related to the example above. The cutter wheel is made with a dead-sharp edge or
point. You will always get ridges on the cut stylus wearsuntil finally you have to buy a new cutter
or get the old cutter resharpened or replace the stylus. When you put on the new or resharpened
cutter or stylus youre back to ridges again.
Machine Makes Whirring Sound
There are four possible causes.
1.
The sound is coming from the motor. With the machine turned OFF-grab the motor shaft
and try to get some movement out of tit when trying to move the shaft up and down. If there is up
and down movement the motor ball bearings are worn and the motor will need replacement some
time in the future. Please ignore any motor shaft play when pushing or pulling the shaft along its
length in and out of the motorthis play is in the motors spring preloaded ball bearings and is not
a sign of bearing wear.
2.
Your drive belt is coming apart or is frayed. Replace it.
