   The T&G straight & wedge bits I've seen are for edge gluing.  If you're making a corner joint, why not a lock mitre bit? Maybe I'm missing something?

   I need to reproduce a number of factory made table tops. Tops are just a outside frame with glass in the center. The original factory top frames are put together with T&G on the corners (not mitered) in a rail and stile fashion. The job requirements are to stay consistant with the factory made one. I'm just wondering why the wedge type of T&G would be a better choice than the straight T&G, or is it.

   The only advantage of the wedge that I can think of is that if the stock is not 100 percent flat, the wedge will mate easier and faster than the straight. The tapered tip is smaller than the opening when they start to come together, and the taper would position itself as clamping force is applied. In a factory the clamping is probably done by machine with very little human intervention. With a straight bit on stock that is not perfectly flat, the tongue could get hung up, and when slammed together by machine, would damage the tongue. Since time is money on your job, you probably would be better off with the wedge. I would think they'd be equal in strength. I'm just guessing here though.
