I've been a wood butcher for nearly 30 years and have seen some horrible accidents.
Most are caused by rushing, using the wrong tool for the work and general stupidity.
Once saw a sparks drill a 20mm hole through his palm. He had one hand holding down
a ceiling rafter while in the other pushing up with a cordless drill and 20mm spade bit.
One of the funniest was an Irish guy who was wearing half an empty cement bag tucked in his
jeans for a nail pouch and using a lump hammer for tacking plasterboard ceilings.
Don't think he'll play the piano again.....
Measure twice....cut once
