I admire your lesson taken from the deceased. If she lived through the Great Depression, her relationship with scarcity was more intimate than our own. Poverty does not bring out the best in us. If you're building boxes with long rabbets in thin stock, much can be done with a sturdy knife (to score with the grain) and a flat paring chisel (to remove end grain to chosen depth). Please post photos if your project.
I recommend both DIYSG and Troels Gravensen webpages for further study. They take different approaches, but the projects are within reach of home builders. http://www.diysoundgroup.com http://www.troelsgravesen.dk Jim
Thanks! I'm not much of a woodworker, so appreciate your tips. I think I'll use some void-free plywood.
Solid wood assembled into a cube will fracture along grain, particularly where screws anchor the drivers. MDF is used because it's easy to machine with high speed tools - not for acoustic considerations. I use plywood, with a little internal bracing. Jim
