Your a tool junkie when you have two working (*Working!*) lathes and are looking for another......
Sick, Sick, Sick. Turn in your 7-cell 1942 flashlight.You have duplicates of tools, to keep the originals in pristine condition.
In the state of GA... that would be referred to legally as a 'booby trap'... which is illegal and will get you may years in jail.
If memory serves... there was a case taken to court years ago (do not remember which state); similar to the second quoted post above; The high school kid's dad was an atty and tried to sue because his kid got a broken finger or wrist or something... from the recoil of the bat hitting an immovable object.
Judge threw out the case.
But ,your honor, I'm a welder and tend to make sturdy things. No booby trap was intended.........hehehehehehehehe
