I was told something similar that by some 60 - 70ish year old farmers . they said "they learn something new almost every year" .
I made a bit to tighten up the gelcaps about 14 years ago. ( the ones you are not supposed to tighten with a drill) very simple. If you slotted a. 1/2 or 9/ 16 socket with a grinder it would work good.
