Perhaps someone can help me with a question about the key
machine I received with the Foley-Belsaw correspondence course.
I know this is not a high-precision machine. For $200, what
can I expect? However, I did expect that with careful use
I could make workable copies or cut keys by code. Now, I'm
not so sure.
I'm having trouble clamping the key or blank reliably, and
repeatably, in the vises. One jaw of each vise is a pretty
solid aluminum casting, but the opposite jaw is made from
an aluminum extrusion which is more flexible. When I clamp
the blank in the vise, this jaw flexes and lifts the blank
away from the back of the vise, changing the depth of cut.
I've watched in horror as the blank rose maybe 0.01 inches
as I tightened the clamp. This offset does not seem to be
repeatable, so I can't cut two keys the same. If I leave
the clamp looser, the blank comes out altogether and the
cutter throws it in my face.
I've tried this on Kwikset blanks, which have a simple,
rectangular shape on the bottom. I don't think this is a
hard-to-clamp blank.
So, has anyone had these same problems? And has anyone
solved them? Is it worth trying to make this thing work?
Thanks for the help.
Regards,
Vince

Due to the price range i have several model 200 machines from foley
belsaw, i use them daily to cut well over 25-50 accurate code cuts for
my customers, the jaws are not really that bad, even a $1500. framon
will do the same thing, keeping a sharp blade is very important,
clamping keys on the most even parts will help out a lot (watch out
for worn out nissan blanks, they'll shoot like a .357 .
i have learned to take my time when code cutting and duplicating
on this machine, i ALWAYS keep my left index finger firm against the
end if the blank being cut, it will reduce vibration and you will feel
them slip before you see them, just dont go to far and cut your
fingers, if you do a lot of copying invest in a speedex duplicator,
around 300 new and pretty darn accurate without as much slippage, use
the belsaw just for code cuts. Yes the belsaw will code cut very
accuratly, you will have to really get used to it though, know your
machine. my belsaw brought me over $40,000 last year using it
professionaly on the job, i do nothing but cars, and make keys for a
truck load of them daily, dont give up.

I never had any such problem with mine - before I got a better
machine.
I can only think of three possible causes. One, the "U" clamp may
be bent - and somehow forcing the blank out of position. The second
possibility is a burr or debris on the clamping surface, causing
the same problem. Third, the "U" clamp may be too tall. It should
not quite reach the clamping surface, when tightened down without
any key blank inserted.

I haven't had that problem either, unless I overtighten the vise.
(Yes, I too have an old F/B machine on the shelf -- it's a cheapie,
but it works, and the micrometer lets you easily set it to cut a bit
higher or lower when you're trying to compensate for wear.)
Remember, some keyways will not sit flat in the vise when clamped.
F/B's manual points out that you will sometimes have to shim the blank
to keep it from rotating as pressure is applied. Higher-priced machines
sometimes have multisided jaws which will handle a wider variety of
keyways without this kind of fiddling around.
