Editing 952: Stud Finder

[[Cueball]] cannot locate his {{w|Stud_finder|stud finder}}, so [[Black Hat]] begins a sales pitch, presumably for a "stud finder" finder. The joke is in the irony of having to find something that is used to find other things. Cueball interrupts Black Hat before he can make the obvious joke. The same comic technique is used later in [[1059: Bel-Air]]. Currently no product exists that will locate a stud finder, although online review compilations are useful for finding the right stud finder to buy.

Studs are vertical wood members in {{w|Framing_(construction)|wood-framed construction}} common in North America, although steel framing has become a popular alternative. These supports reinforce a wall at regular intervals, typically 16 inches (about 40 cm), and at corners, windows, and doors.

Most stud finders use an electrostatic field that is affected by the densities and types of materials in the vicinity, identifying where studs and other significant framing elements are located. One might want to know the locations of studs within a wall for installing wiring, mounting shelves and heavy objects to walls, or in this comic, hanging a picture. Wiring can be inserted between studs behind the {{w|drywall}}, while shelves, pictures, etc. are better affixed to studs. In constructions with mostly solid walls, discovering (and avoiding) any previously installed electric cables or pipes is as important a prelude to any new drilling of holes or hammering of nails, and the same or similar detectors aim to reduce that risk.

Many stud finders have a light that turns on in conjunction with a beep when a higher density is detected, indicating the edge of a stud. But there are circumstances that can fool stud finders. Most are designed for the drywall-over-wood-framing construction, and can be fooled by older {{w|Lath_and_plaster|plaster and lath}} construction where the density is much more uniform throughout the length of the wall. Lower quality stud finders can also be fooled by things like moisture in the drywall or wiring within the wall cavity, and may thus beep when there is not a stud behind the scanned location. As a result, many people will try alternatives such as using a magnet to find the drywall screws or nails, or tapping a finishing nail through the wall to see if there is a stud underneath.

At the title text, [[Randall]] just gives up. Assuming there was no electrostatic interference, a stud finder going off randomly would indicate lots and lots of studs at random places that change position.

 

The idea of a "something doer doer" was explored again in [[1821: Incinerator]], the title text of [[2376: Curbside]], and [[2382: Ballot Tracker Tracker]].
