DIY Electric Pepper Grinder - Cordless Drill to Pepper Shaker Adapter

Step 6 Test, remove pepper grinder and put in another.

Give it a whirl!  If the pepper grinder is WAY off center you can loosen the hose clamp until the pepper grinder can be pulled out, adjust the fingers, and put it back in.  The hose clamp doesn't need to be tight, just barely snug.  This allows you to insert and remove the pepper grinder whenever you want.

Enjoy!
