I read the posts and wonder if times have changed.
I went to a vocational HS (Diman Reg. Voc. HS, Fall River, MA, class of 70). We alternated 2 wks shop, 2 wks academics for 4 yrs. Never saw bad accidents. For first 2 yrs, no machinery - all hand tools (we mastered them one by one). Machinery was big - 36" Planer, 12" Jointer, 5HP Shaper (no feeder), etc., oh ya, no blade guard on the TS either, never mind a arriving knife!
What helped back then, first, most students WANTED to be there and learn, but also, and most importantly, there were shop trade theory classes during the academic wks! These were 2 hrs classes 5 days a week: from trees, sawing & drying, to hand tools, power tools, then machinery, we learned them all - safety, safety, safety! Also, always in the shop were 2 old time woodworking instructors - 1 for 9-10 graders, 1 for 11-12 graders (shop was big). This allowed for close eyes on students and machinery by both teachers since half of the students had no business near machinery - though occasionally, the teacher would let a 10th grader "drop" his hand, face-planed board on the planer bed to "test" how truly flat the face was!
I remember those years well and am thankful I received such training. Although most my working career was not woodworking, in most shops I have worked (6 or 7), it was SO obvious few had formal training, and worse, most didn't want to change their ways! From what I read on this and other forums, there seems to be a more safety-conscience work force. Do you agree?
