Woodturning A-Z

Used on Record lathes to protect the spindle thread and prise the taper mounted drive centres etc out of the morse taper socket. Necessary because Record lathes do not have a hole through the spindle for a knock-out bar.

EMC.
Equilibrium moisture content. Wood will lose or gain moisture to achieve this equilibrium with its environment.

End seal.
This is painted onto the end grain of wood to stop it splitting e.g. Mobilcimer C.
