Answer: Upon assembly of the joint, the end grain is visible in a through or plain dovetail joint. In the assembled joint, the end grain of one of the boards is not visible in a half-blind or lapped dovetail joint. The end-grain is not visible on either board in a blind dovetail joint.
The image to the left is a NORMAL dovetail joint. Half-blind dovetail joints are popularly used when fastening drawer fronts to drawer sides, where visibility of the end grain from the front of the cabinet is not desirable, as opposed to attaching false fronts to drawers constructed using plain dovetails. When the woodworker does not want the finished piece to have the end grain being visible but still needs the strength of a dovetail is when blind dovetails are used.
Question: What is the difference between “Combination Tooth,” “ATB” and “Flat Top” saw blades and which type should I be using?
Answer: Blades that are made for ripping wood feature flat top teeth since they are the most efficient for cutting and removing material out of the cut.
Alternate Top Bevel (ATB) saw blades have teeth alternating between a left and right hand bevel. These alternating beveled teeth form a knife-like edge on both sides of the blade, thereby resulting in a cleaner cut than by using flat top teeth. This particular combination provides for a smoother cut when crosscutting veneered plywood and natural woods.
Combination Tooth Blades have their teeth arranged in groups of five – One FT and four ATB teeth – with a big gullet in between the groups. These blades are designed for both ripping as well as crosscutting.
Question: In almost every article I read about sharpening there is reference to “Scary Sharp”. What does this term refer to?
Answer: Scary sharp is a method used to sharpen woodworking tools by use of a sheet of glass and sandpaper rather than using conventional methods such as waterstone or oilstone sharpening.
