12 inch pine
shelving was the cheapest lumber. It took 4 boards cut to size or
ripped.
I borrowed clamps and glued everything up.
After a lot of sanding and some polyurethane, it was done. You can see the brace that will hold the TV in place. An important tip is to make sure the brace doesn't block peoples' legs.
I tried Maptools and Mote to run the table, but will probably just use Roll20.
The total cost was under $100.
