The set screws that hold the upgraded arms in place would come loose on me and being new to my sharpener I was not as observant as I should have been and when I did look my adjustment arms had moved a lot to the point that The stones were shrinking the sharpener.
Called Kyle and informed him of my problem and he recommended a little lock tite. Also, I received some new screws from WEPS that Allows me to be better able to tighten the set scres using the hex wrench that comes with the unit. Problem solved. Hope thi helps.
