Thanks for the input guys. A Triton will be in my collection soon. I will not however let the students use it. I am offering beginner courses to start, if anyone wants to go more advanced and use power tools, that will be an intermediate course. I will get the students to sign waivers for insurance purposes. For beginners I will show them how the power tools work, but I won't let them use the dangerous ones. In an even more advanced course there could be turning, carving inlaying and other areas of fine furniture making.
