PocketHoles: Testing Wood Joinery Methods

In dereksonderegger/dsData: Datasets for Teaching

Description

One defining distinction between cheap furniture and high quality furniture is the method in which pieces of wood are joined. Low quality furniture is often joined using "Pocket Holes" that are easy and fast to create. One woodworker decided to test several different types of joints.

Usage

PocketHoles

Format

A data frame with 16 observations of 2 variables.

Type

A factor describing the joint type.

Force

The force required to break the joint (in pounds).

The purpose of this experiment was to compare pocket holes to two other common techniques. The dowel holes were deliberately done a bit poorly to simulate a "lazy" woodworker that only uses two dowels, instead of three or four.

The joinery types are using pocket holes with 2 screws, a dowel joint with two dowels (using Titebond 3). The mortise and tenon joints were created using three different types of adhesive: yellow glue, Titebond 3, or epoxy.
