Instant panel saw. Sorta.
Found this the usual way, looking for something else entirely unrelated. Problem was, it was on Pinterest. Twice. At two different sites, and could find nothing more than the photo, no other information available. But that should be ample. Very simple, add a circular saw guide, and you've got a workable panel saw.
Did I mention that I hate Pinterest?

Some days, the supply of available curse words is insufficient to meet my demands.
Call me a craftsman, artisan, or artistic, and I will accept that. Call me an artist and you will likely get a quite rude comment in return. I am not a @#$%ing artist.
