I was lucky when I stumbled across that website after endless searches for an updated Jointer safety test. Thought it was worth sharing. I too, treat the Shopbot as an specialized router when it comes to safety.
I teach CADD (Rhino 3D and Chief Architect), Woodworking, and Computer Repair & Networking for high school students. We started in 1994 with one of the original cable driven Shopbot CNC machines. Since then it has gone through many upgrades. Last school year we added a new steel table and 4G upgrade, but still use the original utility struts for the x & y rails and screen door roller bearings. That will be the next upgrade if I can ever figure out the best way to accomplish it.
The great thing about both CADD and Woodworking is that the ShopBot integrates very smoothly into both subjects and the majority of the students love it.
What class do you teach Wendell?
