Kickback
This is when a workpiece is thrown back by a cutter. Prevented using anti-kickback devices on thicknessers. Modern Spindle moulder blocks and circular sawblades are designed with features to reduce the chances of kickback.

Knot
The portion of a branch or limb that is embedded in the wood.

Lumber
US term for Timber

Mitre Guide ( Mitre Gauge / Crosscut Fence )
A guide with an adjustable angle head that fits in a slot and slides across a machine table to cut material at an angle. There is no standard size for the table slot, many of them are also T-shaped.

Mitre Guillotine ( US term Chopper )

Mitre Saw ( US spelling Miter Saw )
A type of chop saw where the angle of the blade in relation to the fence is adjustable to cut material at an angle, compound miter saws feature a tilting blade as well. A sliding compound miter saw is a compound miter saw with horizontal sliding arms for the cutter head allowing cuts on much wider boards. Mitre saws usually bevel in one direction, however some can bevel in both directions. See our range of Mitre Saws

Tearout
The tendency to splinter the trailing edge of material when cutting across the grain.

Tenon
A projection made by cutting away the wood around it to insert into a mortice to make a joint.

Machine which assembles picture frames by inserting a Vnail into each corner. See our Undeprinners

Vnail ( Wedge )
V shaped steel fastening for joining two mitred pieces of picture frame moulding. See our Vnails

Voltage
Standard UK voltage is 240v. Since European harmonisation, it is often expressed as 220-240v although the actual voltage has never changed. More powerful industrial machines use 415v, also known as 3 phase.
