Production
The history of the finger joint is believed to have begun with wooden produce boxes or crates. Finger joints were originally cut by hand with saws and sharp chisels. In modern times they are easily and quickly made with a table saw or router and a jig or fixture, which can be shop-made or purchased from a specialty woodworking supply store. A finger joint jig typically consists of a moving fence with an indexing pin that is used to evenly space out the cuts. The fence is moved over a cutting blade making a cut that is then moved over the indexing pin so the next cut can be made.
While it is relatively easy to make using computer aided manufacture, a table saw or a wood router with a simple jig, some common problems include:
- Tear out on the back side
- If using a table saw, the top of the joint may not be exactly flat, depending on the tooth set of the blade
- Spacing problems and difficulty dialing in the exact index

Famous quotes containing the word production:
“It is part of the educator’s responsibility to see equally to two things: First, that the problem grows out of the conditions of the experience being had in the present, and that it is within the range of the capacity of students; and, secondly, that it is such that it arouses in the learner an active quest for information and for production of new ideas. The new facts and new ideas thus obtained become the ground for further experiences in which new problems are presented.”
—John Dewey (1859–1952)
“I really know nothing more criminal, more mean, and more ridiculous than lying. It is the production either of malice, cowardice, or vanity; and generally misses of its aim in every one of these views; for lies are always detected, sooner or later.”
—Philip Dormer Stanhope, 4th Earl Chesterfield (1694–1773)
“[T]he asphaltum contains an exactly requisite amount of sulphides for production of rubber tires. This brown material also contains “ichthyol,” a medicinal preparation used externally, in Webster’s clarifying phrase, “as an alterant and discutient.””
—State of Utah, U.S. public relief program (1935-1943)
