-[* icon_note] Clockmakers (horologists) have their own jargon which we will use, as those are the terms you will come across if you seek help and guidance elsewhere.
-[* icon_note] The spindle on which the gears are mounted is known as an ***arbor***.
+[* icon_note] Clockmakers (horologists) have their own jargon which we will stick to, as this is the terminology you will come across if you seek help and guidance elsewhere.
+[* icon_note] The spindle on which a gear is mounted is known as an ***arbor***.
[* icon_note] At each end of an arbor is generally a thinner section. This is known as a ***pivot***, which engages in a ***pivot hole*** to form a bearing.
[* icon_note] A small gear is known as a ***pinion***.
[* icon_note] A larger gear is known as a ***wheel***. A wheel frequently engages with a pinion to form a reduction gear. Several such together form a ***gear train***, transmitting the power of the spring to the escapement and the hands.
[* icon_note] A wheel and a pinion are always mounted on parallel arbors, however, a ***contrate wheel*** (like a crown) can engage with a pinion on an arbor at right angles.
