This editor has found that a K&M screwdriver-type case holder CAN work securely if you tighten the locking mechanism tightly with the supplied wrench. But then you need the wrench again to get the case OUT. We were interested to see if there was a better solution that held the case securely, yet was easy to lock and unlock without tools.

Forum member Gunamonth provided a solution: “I use a Lee Zip Trim three-jaw case holder. With a little practice it centers the case quite nicely and holds just about anything. Chuck it in a cordless drill and have at it. It is much better than either the K&M or Sinclair [case-holder] in my opinion and the Zip Trim jaw is a lot cheaper (about $12.00). To use with power, you also need the Zip Trim three-jaw spindle, which is another $2.00.”
