The Essentials of Custom Design for Professional Woodworkers
From the selection and design of the right fit to the exact work sequence, know-how, and transformation methods.

Many modern people enjoy woodworking as a hobby and work on small furniture and household items for their homes.
The joy of woodworking is transferring the design in your head to a drawing and watching that design become a real thing.


When doing woodworking, no matter how hard or large the wood is, if you are not technically skilled, stability cannot be guaranteed.
This means that precise and meticulous techniques are absolutely necessary to create sturdy wooden products.
Especially in woodworking, shrinkage and expansion are inevitable factors.
If a nail is inserted here, the moment it contracts and expands, the nail will come out and the wood will warp.
At this time, if you use a 'fitting' method instead of screws or nails, it actually increases the bond strength by pulling the joint strongly.
So, custom-made furniture shows durability and aesthetics that are on a different level from the furniture we know.
Fitting is a high-intensity job that requires not only physical strength but also skill and experience.

《Woodworking Joinery Design Textbook》 introduces over 70 joining techniques that can be used when joining wood to make joinery furniture.
A selection of essential techniques that can be widely applied to all woodworking tasks.
It includes detailed and professional explanations and 3D illustrations to help woodworkers further enhance their furniture-making skills.
By applying various joining techniques, you can create sturdy and beautiful wooden furniture that looks like it was made by a master carpenter.


Using the right tools and processes will improve the quality of your fit.

The fitting developed by changing the direction and angle or modifying existing techniques based on the basic method to meet the characteristics, structure, and aesthetic requirements of the absence.
Therefore, to efficiently carry out the work, you must know the structure and purpose of various joining methods and select the right fit.
This book first explains the method and purpose of arranging joints according to the direction of the wood grain.
Because no wood is stable, it is important to predict shrinkage and expansion and design the fit accordingly.
The design strategies presented in this book can help you properly prepare for specific types of stress and reduce the risk of component failure.
