The following post gives an overview of the development of the wooden screw making methods I’ve developed. Along with the tools and methods and how they evolved I will provide a more personal story line for those who are interested. Above are the first taps and dies that were made using the 1977 Fine WoodworkingContinue reading “A Brief History of my screw making efforts”

Tap Cutter Geometry
This is my 14th post on the topic of making wooden screws. Most of the main points have been covered and the posts may even give enough information to create your own tooling. If any of the information is confusing or if you have questions please ask; you may provide topics for future posts. TheContinue reading “Tap Cutter Geometry”
Die Cutter Geometry
A die cutter is made from a pair of HSS lathe bit blanks. The blanks are square in cross section and around 2-1/2″ long. 1/4″ square blanks are big enough for my biggest thread, 3 TPI. A larger 2 TPI thread would require 5/16″ blanks. 3/16″ square blanks are good for my 4 TPI threadsContinue reading “Die Cutter Geometry”
Thread Design for Wooden Screws
This post will attempt to explain a method of designing a thread of any size; a necessary step before starting to make the threading tools; tap and die. (1) Choosing a Thread Angle The first step is to decide on the THREAD ANGLE. Many threads in metal and in wood have 60 degree thread angles.Continue reading “Thread Design for Wooden Screws”
