DIY Electric Pepper Grinder - Cordless Drill to Pepper Shaker Adapter

Step 4 Fit the clamp to the pepper grinder.

Place the top of the pepper grinder into the rubber cage you now have and tighten the hose clamp up.  As you go, you may need to move the fingers around to keep them equidistant from each other.  Once it's tight, you should be able to pull the pepper shaker in and out without too much effort.
