got me wonder so I decided out of boredom to tear apart an old Savage speedometer. (can not successfully open it up without destroying the chrome bezel keeping the speedo glass in place). This is what is inside, as you can see, there are no electrical components, it is completely mechanical.

That drum in the middle is magnetic ain't it?
Couldn't tell you how fast to spin the drive shaft, but you might take a drill motor and chuck the drive shaft in it and let 'er rip to see what "speed" you can go. Since a chain drive has gotta make it about 10% slower, try a tape head demagnitizier and briefly bring it up to the drum for maybe a second. Then run the drill again to see if it still works or if you slowed it up any. Try again only longer. Keep at it notin' where you rub the demag and fer how long. Have fun.

Vers, yes they are magnetic. I have torn apart about 3 others from the early 70's forward and that wheel is a magnetic drive connection with the spring countering the magnetic force as the RPM of the magnet increased. It is amazing they are as accurate as they are!!! I can also understand why they are going to electronics too!
