I've turned a few sets of grinders using this kit from PSI in the last few years. They are always well-received as gifts so I thought I'd post them here all together just in case it gives any turners ideas
The first picture is a pair of Mesquite with a maple cap for the salt and a Walnut cap for the pepper. The second two pictures are a pair I made with Maple for the Salt and Walnut for the pepper. The fourth picture is curly Maple for salt and Katalox for pepper. And the last photo is a curly Maple pair with a Katalox cap on the pepper.
While I enjoy freshly-ground pepper I don't know that there is really any advantage to grinding salt fresh. But most folks have matching salt and pepper shakers so I made them in pairs anyway
The kits are well made and the grinding action works very well even after regular use for a couple of years. I will say, the instructions with the kit say to use a jam chuck but I made some aluminum bushings to use with my pen mandrel to turn them and it works much better for me. I like having the reference of the adjacent diameters to work to so I can visualize the shape a little better. Also, the instructions call for a 1" drill bit for the blank. But the kit parts are only about .985" diameter so I use 2-part epoxy rather than CA glue to glue the kits in so it will fill the gaps.
Thanks for looking. Comments and questions welcome as always!
