For years I have struggled to find a good way to control the depth of a drilled hole using a hand drill. I have tried the painters tape to mark the depth but inevitably the drill bit will grab the wood and slide the tape up. Same with those little sleeves with the allen screw in the middle of it, the first time the bit grabs the wood the sleeve slides up. Yesterday I came up with a method that seems fool proof. If this fool can do it that is proof anyone can do it. Using what Harbor Freight calls Rare Earth magnets I put 3 magnets on the jaws of the drill chuck and used as many hex nuts as need to stop the bit at the desired depth and nuts with a center hole to fit as snug as possible to the size bit being used. Worked like a charm and as long as I make sure none the the nuts slip off the bit it isn't going to drill any deeper that desired.
