OK, Today I began gluing up the blank for the top of the living room side table I'm making. Really boring, eh.

Spent some time this weekend helping a friend build an enclosure for a portable speaker system. It looks a bit complicated for a portable speaker build but each compartment has a specific purpose. Each speaker will have separate mid range and tweeters. A small subwoofer with a tuned port will be installed in the center cavity. A 12v 50amp bluetooth amplifier and two old Dewalt 18v batteries will power this system. Initial power tests achieved 18 hours of play time at mid level volume for a single battery.

I made an inset wooden tray for my spouse. She likes that dessert dome and asked me to make a tray for it. The wood is soft maple and walnut. To be honest, I had thin leftovers of maple to use up. Otherwise, it might have been solid maple. The finish is four applications of Howard's Butcher Block Conditioner (mineral oil, beeswax, and carnauba wax).
This was a simple project. The biggest challenge was computing the radius of the corner curves knowing only three measurements: (a) length, (b) width, and (c) diagonal from curved corner to curved corner through the center. Hint: Remember how to solve a quadratic equation?
I set a compass to the correct radius and made a quick pattern using a thin "square corner" scrap and a disk sander. I used double tape on the pattern and a flush trim bit on the router table to shape the corners. I used a 1/4 inch roundover bit on the bottom to match the curved bottom edges. I clamped a scrap backer inside and used a Forstener bit to drill a finger hole through the bottom of the dome to make it easy to remove the tray for cleaning. A little delicate filing (the hole), a little sanding (grits through 240), a few coats of finish. Done.
Nothin' to write home about.

Worked on building a subwoofer and a couple of speakers for my shop today. I finished the speaker boxes over the last two days and got through wiring the two speakers tonight. They sound really good even without the subwoofer. I'll finish wiring and mounting the subwoofer tomorrow and connect up it's dedicated amp. It should sound great when everything is done. I'm going to run them in just the plywood boxes for a month or so. I'll do some frequency response testing and some general listening. If the speaker box and crossover design works as I hope I'll end up wrapping the speakers and subwoofer in cherry and build some grills to dress them up a bit.

My shoulder has been in really bad shape and haven’t been able to do much. I’m trying to build a small shed to store concrete in but can’t pick up sheets of plywood and needed something to move plywood across rough ground with rocks. I just received a plywood dolly that I ordered from HD and put it together. I have to say I’m really happy with this and wish I would have bought one years ago.
