I have the Hobar workbook called: Power Tool Safety & Operation. It has the part ID, safety procedures, and the completion questions for all the different tools, such as bench saw, sabre saw, drill press, etc. I used to have the tool ID pictures and the answer keys for this, however in my move to a new school this year I somehow misplaced my answer keys. I was wondering if anyone had the answer keys for the completion questions and the parts for each tool? If so would you be willing to share this with me?
