I respectfully disagree. There are so many things that could happen that no High School student could possibly be aware of. All it takes is one accident and blame will live with you for the rest of your life.
Al, I was a Woodworking technology teacher and was fully credentialed. I had taken Technology/engineering classes at the 2 of the largest universities and most respected and prolific teacher training facilities on the west coast. As well I had attended 3 additional universities, obtaining a math credential,masters degree, ....
As part of the curriculum for both Tech Ed, as well as an Engineering prerequisite we spent an entire semester studying accidents, safety precautions/procedures... also have had experience working in construction, had a small cabinetmaking business, attended conferences such as meeting with an expert court witness that job was to win the plaintiff's case against the Industrial Tech teacher such as myself. Lots of questions, handouts, procedures, templates for specific push sticks...
I have done my DD and the cradles were built under my supervision, from material choice, drawings,... Also won the county competition judged by other professionals, and finally the his parents took possession of the cradle not him. (We didn't send many projects to state because of a past history problems of breakage in transit, or when being handled, setup/taken down, but feel the project would have scored well.) BTW, I taught Woodworking technology for almost 20 years, never had any
type of serious injury. When I said DD I really did mean exactly that. Accidents can and do happen, but prevention can go a long
way. You have to know what you are doing, especially with a project of this type.
You know there have been many wooden boats built, houses built in earthquake zones like the area I live in. I really belive in freedom of choice, the rights of the individual, and of couse education. Can no one be taught to do anything anymore? I mean this in the most positive way. Society is becoming too restrictive. So many policies, laws, ... are robbing us of the chance to develop common sense and scrutiny of thought. Now that is dangerous!
