We are entertaining the idea of working on a project with our local high school woods class. We are in a small town and the kids are not exposed to any automated equipment and we thought they could really benifit from the shopbot in our shop and other tools. This would require them to be in our shop for a couple hrs each week. We are checking with our insurance carriers about liability. Does anyone have experience in what they had done in a similar situation? Waivers signed, etc. We don't want an insurance issue to put a hold on the project, but at the same time we have to make sure there are not any extra costs that we can avoid. Thanks in advance for your help.
