Lapping machine. Lapping is a machining process in which two surfaces are rubbed together with an abrasive between them, by hand movement or using a machine. Lapping often follows other subtractive processes with more aggressive material removal as a first step, such as milling and/or grinding. Lapping can take two forms.
Coarse scraping gives a resulting surface with 5-10 points per square inch while fine scraping yields 24-36 points per square inch. If desired, the surface can then be "frosted". A surface prepared in this way is superior in overall accuracy to any prepared by machining or grinding operations, although lapping can equal or exceed it over small ...

Most commonly, plays occur at the snap during a down. These plays range from basic to very intricate. Football players keep a record of these plays in a playbook. [1]
The Patriots, meanwhile, were fined $1 million and stripped of two draft picks, including a first-rounder, even though the league-funded “Wells Report” could only conclude that it was “more ...
These techniques, along with Vick's unusual athleticism, slowed down and isolated defenders and provided extra space and time for the quarterback to survey the field and/or run the ball.
