I have a lady friend that likes to do woodworking. As she does not have many tools, likes to come over and use my tools. My principle is that it is under my supervision, which is ok by her. When it comes to sharp tools I want to be there, say saws etc. When it comes to sanders I will let her do it on her own. Same with drill motors.
The other day she used a sander without a sanding pad on it and and managed to sand the velcro hook off the pad itself so now the pad will not except the sanding discs. The sander is no longer available so it is useless. Yes it is old but was in good working order.
My question is whether I should chalk this up to my experience or ask her to pay some of the cost?
