I have never cut myself with router, table saw or chainsaw. I did manage to nick myself with a bandsaw. Probably for same reason you cut yourself with the JMP. The blade becomes almost invisible. It makes no noise and even while looking at it, it is doubtful one would think of it as imposing enough to do much damage.
I have used a "mental" approach to using new tools that I have not been familiar with. Even tho confident, i go thru dry runs with the equipment turned off. I think about the dangers and go thru the operation with great thought about how to do every move without getting my hands into danger. i think about what not to do and then go thru motions avoiding mentally the "what not to do's".
When I zipped into my finger with the bandsaw, I first shut down machine, then checked and applied necessary bandaid. Nothing major, just a slight nick into the tip of finger nail and skin at end of finger. Once bandaid was applied, I manually went thru every problem i could think of for cutting >>> with BS turned off. Even now, after several years use, I still go thru the motions ocassionally just to keep me thinking. I no longer have a table saw in my shop, but if i do return one to the shop, I will go thru the motions as if i had never used one in my life.
i think something like that would be appropriate for new users of the JMP. It is so much different in technology and operation, as well as the blade being motionless and noisless, I am sure we will hear of others cutting themselves with the first few uses
I am sure many of us have watched "Nahm" brush the Tablesaw top with his hands so close to the spinning blade before he makes a cut. My heart is in my mouth every time I see him do that. (and he does it so often it is plainly a habit he will probably never break) I even yell at him. My wife thinks I am crazy. Oh well. She has known me long enough that she knows for certain>>> that's another story

I just don't think that is a great example to be showing any newcomers to WW'ing. If I had a guy working for me and caught him doing that, he would be gone the second time I caught him at it. I give him the two times as by the time he did it the second time, his ears would still be ringing from the first time. there are just so many ways to get hurt with any kind of machinery.
