I imagine the factory has ten different jigs they use for cutting and finishing panels. And even so, some are better than others. I would not want to try one freehand.
Also, what was the purpose of the step cuts on the old English tenons?
A very good question indeed. I've panelled round pipes, and I've started square and done the "rounding" at a later stage, and ... probably... probably that's a little bit easier. It's very weird though to take a block of briar, run it this way and that way, and another, and like this and NOW ... now it's ready for 5 minutes on the lathe.What I've wondered about this shape is: do they turn a billiard then flatten the sides or cut the four faces then round the corners?
Yeah I can imagine how odd that would feelA very good question indeed.

I know @tfdickson and @solideogloria86 have some from Ryan Alden.
@sasquatch has done at least one that I've seen.
@TheIronMonkey do you have an 502, 506, or 515 pipes in your collection?
I always thought they were for a better tenon/mortise fit. I must have read something about it somewhere, but I don't remember.Also, what was the purpose of the step cuts on the old English tenons?
I'll tell you my opinion: the panel was born (like other shapes, especially free hand) in an attempt to avoid the imperfections of the briar.What I've wondered about this shape is: do they turn a billiard then flatten the sides or cut the four faces then round the corners?
