Installing A Pepper Mill Mechanism
Installing A Pepper Mill Mechanism

Including how to shorten the drive shaft
pepper mill mechanisms are very simple machines. A long drive shaft is secured to the head of the pepper mill so when turned, it rotates the grinding cutter within the female grinder at the bottom of the pepper mill.
While installing this hardware is simple, it is important to be sure it operates freely and that sufficient adjustment is available at the knob to allow the user to set it for a full range of particle sizes. This can involve shortening the drive shaft, a simple procedure we will cover later in this article. I buy my pepper mill mechanisms longer than needed and then tailor the shaft to fit the pepper mill rather than restrict turning the wood to a specific length to fit the drive shaft.
Check the Mechanism
Lay out the pepper mill mechanism to be sure all of the parts are present and that they fit together as designed.
Though rare, finding a problem with the hardware now is much easier to deal with than after it has been installed. Besure to screw the top knob onto the shaft fully as the
threads can be a little rough. Usually, if the knob feels tight when screwing it onto the drive shaft, running it on and off a few times cleans up the threads and smooths operation.
Be sure to use a wire brush to clean shavings from the threads as you do this to prevent future problems. http://www.kairun.com.cn/
