I think this one cost me around 8 bucks, but I can't remember exactly.

Well.. you guys have inspired me to have a go at making a medeco cutaway. Let's see if I can manage to not make a bloody mess of this.

Noah,

I don't want to stir the pot here, but that is not a biaxial medeco. It appears to be a standard "air" keyway version.

Is mine a real one?

Db if your useing a miller to do it i can take a few pics to show you where to cut if you want based on my attempt so it doesnt look as bad as mine.

I used a 2.5mm slot drill to mill the slots and a bigger one to mill the flat.

Shrub,

No, you lock does not appear to be a biaxial either.

Whats the differancing factors then?

by **zeke79** » 15 Jun 2006 13:48

I'll post some pics of the key differences tonight. The basic differences are fore and aft cuts.

Some guy e-mailed me that doubted it was a biaxial, too. I'll set things straight.

Top 2 are biaxial, bottom is standard. You can see the spacing differences made by fore and aft cuts.

I don't see any false gates on the pins either. How many Medeco models have those? (so I can avoid them ;-)

Zeke,

My key is simular to the bottom one but has the little nick at the bow like the top two the serial number also begins with B if that means anything.

I have to say i dont fully understand what im loking at here, i see the 3 keys of course but dont quite understand the differance you are pointing out unless it is the little cut on the blade at the bow side.

I will post a pic of my key in a min.

Note the odd spacing between some cuts on the top two keys that is not present in the bottom key. Some cuts are closer together on the top two keys and some are spaced far apart while the bottom key keeps a standard spacing.

The 2nd "axis" in Medeco "bi-axial" refers to the pins. That means, each pin has to be at the right 'height' for the shear line, as well as at the right 'angle' for a sidebar to drop into a cut in the pin (there might be "false gates"/cuts as well).
The end of the pin is therefore not round, and the key cuts are made at angles that are not necessarily 90 degrees, usually not.
And that is what you can see in the picture of a key.

mh,

What you just described is the rotating pin pricinipal. The biaxial system uses a fore and aft cut system to increase key differs if I am not mistaken. That is what is represented in the pictures. All medeco locks utilize the rotating pin principal, biaxial or not.

by **devildog** » 16 Jun 2006 8:11

I thought that 'biaxial' indicated the rotating pin system, and that's it, now it seems to simply be a keyway like 'schlage C' or 'Best FM', so now I'm really confused!
