We do ask people - and they routinely lie to us about it. But frequently, same folks show up in class a little later, so I guess you could call it spreading the word.
It won’t be honor system for much longer. We’re testing the new RFID interlocks now, and ultimately and perhaps soon - no tickee, no shirtee. The interlock checks the database in real time, and will not energize the tool if you have not taken the class. You can see an interlock now on our cnc router.
Best advice on a basics class - work out a syllabus that’s long on safety and hands-on experience - nothing succeeds better than people doing it themselves under the encouragement and guidance of an instructor. It not only cements in their minds the right way to approach the machine, it lowers their fear of the machine - which often discourages new users from getting started on them. In a sense, the classes should have a “welcome to our shop” element to them.
Also - train trainers first. You need several willing people to teach, not just one or two. Instructors don’t need to be machinists - they just need to know how to teach the syllabus. Weirdly, the act of teaching, is itself, a tremendous teacher. Instructors get good fast. Once you have some trainers, set a regular schedule, and bust hell to keep it running. Its hard, but regular classes are a necessity for required classes, Oh, and the big boost in honorariums, sure does help your committee budget.
Lastly, one rule for everyone. If you make a requirement, then enforce it equally, without playing favorites. But expect some indignant members along the way. Stand your ground.
