Yeah, I think if you’re going to do a lot of thin strips, a jig is worthwhile (and that seems like a nice method). I liked just using the featherboard because it worked (surprisingly) well, felt safe, took a matter of seconds to set up, and doesn’t require me storing a jig (I’m tight on garage space).
I’ve totally had that happen to me before :(
That said, I love my honeywell(?) half-face respirator otherwise. It beats a standard face mask in comfort by a mile. I even got some paper N99 filter sheets + reusable holders for them, which works great and makes it so I don’t blow through plastic cartridges.
