Finished my OS. Sound great for my first build. Sorry I don't have good pics along the way. Finish isn't great, ok. It is stained, then rubbed with 4 or 5 coats of seafin teak oil.
More pics. Winged the damping, using loose acoutistuff behind the woofer. I couldn't find a spec for quantity or type of damping material. I ended up using the aucoutastuff rec. for this volume of cabinet. On the port tubes, I ended up cementing them with ABS cement I had on hand. It worked really well. It is permanent, no undoing it. Also, the port tubes were too large to fit through the hole on the back. A little sanding resolved this. The binding posts simply would not "tap" into the holes, even with a significant amount of "tapping" with my rubber mallet, with enough force to bend one. I then discovered that a nut on the inside easily sat them in the cabinet.
A pic of the cabinet being assembled. One tip that a woodworking buddy gave me that I found really useful: using a cheap painbrush to apply a thin and even coat of wood glue (Titebond).
Ordered these in early December. Completed over the course of probably 5 days sessions between now and then (plus 5 days of finishing, with a day between each coat). Under 6 months. Not too bad for me. I'm sure they could be done in a weekend, not including finishing (pesky drying time).
