Timber framing is the method of creating framed structures of heavy timber joined together with various joints, but most commonly originally via lap jointing, and then later pegged mortise and tenon joints. Lengthening scarf joints. Diagonal bracing is used to prevent "racking", or movement of structural vertical beams or posts.[2]
Originally, German (and other) master carpenter would peg the joints with allowance of approximately an inch, enough room for the wood to move as it seasoned, then cut the pegs and drive the beam home fully into its socket.
To cope with variable sizes and shapes of hewn (via adze or axe) and sawn timbers, two main carpentry methods were employed: scribe carpentry and square rule carpentry.
Scribing was used throughout Europe, especially from the 12th century to the 19th century and subsequently imported to North America where it was common into the early 19th century. In a scribe frame, timber sockets are fashioned or "tailor-made" to fit its corresponding timber; thus each timber piece must be numbered (or "scribed").
Square-rule carpentry was developed in New England in the 18th century. It used housed joints in main timbers to allow for interchangeable braces and girts. Today, standardised timber sizing mean that timber framing can be treated incorporated into mass-production methods as per the joinery industry, especially where timber is cut by precision CNC machinery.
Mortise-and-tenon joints are among the strongest joints in woodworking, and are used for projects that have frame construction and need to be strong. Chairs and tables use them as does most Arts and Crafts and Mission style furniture.
Mortise-and-tenon joints come in several types — stopped/blind, through, angled, wedged, and many more — but they all consist of the same basic parts: a mortise (a recess cut into a piece of wood that accepts a tenon) and a tenon (a tongue at the end of a board that fits into a mortise).
Here's an introduction on how to make three of the most common mortise-and-tenon joints — stopped, through, and angled. You can make any of these joints with one or a combination of techniques. If you end up doing much woodworking at all, you'll quickly become an expert at making these joints regardless of how you do it.
Tenons can be made with or without shoulders (a squared off notch on a tenon; see Figure 1). Which way you choose to do them depends on the design of the piece and your skill at making the joints. Hint: A shouldered tenon can hide less than perfect joinery.
I just happen to see this on the Woodwrights shop on PBS this weekend. when making a mortise use an auger to remove the bulk of the material and clean with a regular chisel or a corner chisel. You could probably make that mortise in just a few minutes. If you insist on hand tools you can could use a hand powered auger.

Great video Cody. As you mentioned last night in the Bible study; "you never know how some little thing you say or do will influence the life of another". Just think of how your videos will possibly motivate and influence others. Watching a video may be that first step on a journey for someone. Keep up the good works.
