@Immortan D, I think you were on the right path. I just threw this together and I think it'll help me make a pseudo domino mortise with the drill press (and maybe some chisel work):
here it is humping the leg of my table:
Now I just need a 6mm drill bit. I tried to use a 7/32" drill bit and it's just a bit too snug. Rather than trying to finesse that, I'll go grab the right size bit. Oh, and I need to remember to drill in the right hole when I get to using this thing!
My professional photographer friend is shocked and amazed at the way folks on "my forums" share and interact and even do tutorials to show each other how things are done and can be done differently. In "his forums" techniques and methods are tightly secreted. If anyone is naive or brash enough to ask "how did you get that shadowing effect?" they will either get crickets (at best) or blasted (at worst).
