Glossary T

TPI

[eventually make one entry for each] Teeth per Inch or Threads Per Inch. Often used in reference to band, scroll, or jig saw blades. Number of threads per inch in a machine screw or pipe thread.

Table

A term in the vocabulary of woodworking with many connotations. As well as the common piece of furniture for eating, working, includes top surface of "Table" Saw , Shaper , Drill Press , and other similar power machine tools.

Briefly, "Table Saw" is frequently also called a "Bench Saw" or a "Contractor's Saw". A Bench Saw, as the name implies -- a Bench Saw comes without legs to support it -- sits on a "Bench" or specially built Table or Bench. Perhaps the most popular power tool among woodworkers today, a Table Saw features a Circular Blade driven by an electric motor mounted underneath the table, with the Blade -- adjustable by height and angle -- projecting up through a narrow opening -- the Blade Slot -- in the table.

Tripod table

A small pedestal table with three curved legs supporting the pedestal.

Table Insert

zero clearance throat plate

Also Throat Plate or Zero-Clearance Throat Plate.

The image shows a so-called "zero-clearance-insert", where -- to reduce Tear Out or Chip Out -- the gap between the blade (and teeth) are minimized.

Tailpiece

The projection of the seat part at the rear of a chair where back spindles are supported. A Windsor chair is of this construction.

Tambour

Taper, Taper Cut

taper

An "off-square" or angular cut, especially on a furniture part, such as a  table or chair leg, that gives one end of a workpiece a narrower dimension than the other end. On tables designed with tapered legs, for example, two of the four sides -- the inside edges -- are tapered, giving the legs a "rakish" look, that softens their often heavy, squarish appearance. Also "Socket" for holding a Spindle on a Shaper .

Taper Jig

A device for cutting tapers on the Table Saw. [need image]

Tear Out

Tear Out is the term given for the small (and sometimes large) pieces of wood that separate from the surface of a board when working it with a tool, typically at the exit point of the saw blade, router bit, or drill. Similar to Chip-out. Throat Plate or Zero Clearance Throat Plate, above is an example of a Jig designed to minimize tear-out.

Template (also Templet)

Tenon

Thicknesser

See Planer

Thicknessing

The process of making a board of equal thickness on the two wider, flat sides. Thicknessing your own wood saves you time and money. While this simple technique is normally done on a thicknessing Planer, you can also do it with these four tools -- Belt Sander, Bandsaw , Jointer and Overarm Router.

Throat Plate

See Table Insert

Thrust Bearing

: "A support which assumes the load of a shaft parallel to the axis of the shaft preventing it from moving longitudinally"

Source Home Craftsman 4 1935 July-August page 260. Yikes! A simpler definition comes from the anatomy of the bandsaw, where two "thrust bearings", one above the table, one below, placed at the back of the blade, prevent the blade from bending as  workpieces move from the infeed side to the outfeed of the table. For Resawing operations, ie, making cutting Veneer, especially, where infeed pressure is exceptionally great, the thrust bearing is essential for maintaining the blade's straightness. See my syllabus on the Bandsaw.

Toenail

Nailing a stud to the bottom plate at an angle; usually at 30 degrees from the stud. 45 degrees is best (if possible)
