Last night, picked up a sheet of MDF, had HD cut it into three pieces so I could fit it into the SUV, got home and cut pieces for the two remaining double thickness baffles, and glued them up so they'd be ready to go today.
Today, marked and routed the holes for the waveguides, woofers, and slot ports - lots of sawdust. Jasper jig for the woofers, template / bushing for the waveguides, and clamped on guide for the slot ports.
Not CNC, but came out pretty well - will do cleanup and roundover of the slot ports, and the baffle edges once the baffles are attached to boxes. Oh that reminds me, I still need to do roundover on the back side of the woofer cutouts (and I guess waveguides for good measure) before assembly.
I left the cutouts for the body of the waveguides (back side) pretty sloppy, not sure if that matters.
I thought I'd be able to start on the boxes this weekend too - had a place all lined up that carries Baltic Birch plywood, went over there during lunch break yesterday, but the guy at the counter says "oh, if you need the sheets cut, you'll have to call ahead and pick them up the next day" (of course the next day is the weekend, and they're closed). So struck out on the BB - maybe I can call another place and pick up what I need before work one day this week. Stuff is like gold, $45-50 per 5x5 sheet, but what the heck, even crappy plywood is expensive here.
