I finally took the time to make the bottom finder.
Some of you may not have seen them. It just takes a laser pointer and whatever scrap you have around.
Just slide in into the bowl and the laser will mark the outside at the exact depth of the interior. It pic has a lot of red due to the camera, in reality it is just a red dot.
I used threaded rod so I can adjust them easily. I may slide them back to about 8” deep as I have never turned anything over 6-8” deep anyway.
They who can give up essential liberty to obtain a little temporary safety, deserve neither liberty nor safety. Benjamin Franklin
