I recently contacted Crushgrind Demark and they kindly provided me with the attached 2 pdf,s which may be useful refences when drilling holes for Crushgrind mechanisms

Please note the dimensions in the attached Pdfs above may differ from the instructions provided by some supplies of Crushgrind mechanisms

The definitive guidance on using Crushgrind@ mechanisms can be found in Turning Salt & Pepper Shakers and Mills by Chris West. Do not attempt to make a Crushgrind@ salt/pepper mill until you have consulted this book. - John

Also good instructions come with crush grind kits from Craft Supplies.

The assemble instructions state

3. Cut off the two clips on the top of the Crush Grind®mechanism

There is an alternative method to this approach to use a Sorby or Crown Crushgrind tools to cut a recess
Separately another approach suggested by some turners is to make a recess tool using an allen key mounted in a handle

I would be interested to know how many turners have used this approach of making a tool from an allen key and how successful they were

I made a recess tool by grinding an old scraper in a handle. (I keep a box of cheap or free old tools for making special tools as needed.)

I have also cut a slot for the tabs with a small cutter on a Dremel. This is harder but does work.

BTW, in either case I leave the clips on AND use epoxy.

I note the differences in drilling the mill head, 7/8 dia by crushgrind (and West), and 15/16 from craft supplies. I've made quite a few of these and find the "best for me" method is 15/16 dia and epoxy+tabs left on. I use the sorby recess tool.
