Locking miter join notes

[mjrgh]

Your diagram of the locking miter join in the readme is true to the WPC originals, but the references you point to are a little misleading, since they're all about a different kind of locking miter, done with a special router bit. The router-bit method is probably the most common way of making these joins these days, but it doesn't create quite the same kind of join, and not as good a join for plywood. The problem with the router bits is that they're constrained by their one-bit-does-it-all design to cut a symmetrical, mirror-image pattern, so all of the features have to appear twice across the width of the join, which reduces their size. That makes them fragile when rendered in plywood, which is why there's so much discussion in the references you point to about all of the downsides of this join and its questionable suitability for pin cabs. The original WPC join, in contrast, isn't symmetrical, which allows its features to be coarse enough to work nicely with plywood. And surprisingly, it's actually an easier and more reliable method - those special router bits are notoriously difficult to set up properly, and they require lots of special handling to get a halfway decent result with plywood.

Anyway, I thought I'd mention it in case you want to update your readme. I got interested in this recently and learned how to execute the WPC joins, and I documented both methods in depth in my virtual pin cab build guide. I can send you a link if you'd like to add that as a reference here.
