Prolong the learning experience from Course Eén and learn to make four different woodworking joints!
What will you learn?

The blind mortise and tenon
The mortise and tenon joint is one of the most common joints in woodworking. The first joint you will learn to make is the blind variant of the mortise and tenon joint.

The through mortise and tenon
The through mortise and tenon is another variety of the same joint and requires a little bit more work and precision than the blind one.

The box joint
A very common wood joint used for case constructions is the so-called box joint, sometimes also known as the finger joint. This is the joint we will learn to make in the third lesson.

The dovetail joint
We will end the course with the most characteristic of the all the joints: the dovetail joint.

Offer this course as a gift to someoneexpand_more
It is also possible to offer this course as a gift to someone else. You can do so in two ways:
- Choose a class yourself in the schedule above and book it for the recipient. If you want to keep it a surprise for the time being, fill in your own contact details during the registration.
- Buy a gift voucher and give the voucher to the recipient. The recipient can choose a class themselves depending on their availability and use the voucher for payment. Click here to buy a voucher.
Note that vouchers are not available if there are not enough classes available in the schedule. With limited availability, there is nothing or too little to choose and that defeats the whole purpose of the voucher. In this case, you can revert to the first option.

menu_bookCourse program
expand_circle_downIn Course Eén you have already learned the basics of artisanal woodworking and know what the making process looks like from beginning till end. You also learned about the importance of woodworking joints, because these play a crucial role in creating things out of wood.
The more woodworking joints you know, the more things you will be able to create. That is why Course Twee aims to expand your knowledge about traditional joints and teaches you different woodworking joints.
As a participant, you will
- Acquire knowledge about traditional joinery in general
- Learn to make four different traditional woodworking joints
- Learn new skills with hand tools
- Develop your skills from Course Eén to a higher level
Attention: Course Twee is part of an integral learning trajectory offered by Atelier Espenaer that starts with Course Eén. Course Twee can only be joined by participants of Course Eén!
emoji_peopleFor who is this course?
expand_circle_downCourse Two is only accessible to participants of Course Eén. This is because Course Two is part of a integral learning trajectory that starts with Course Eén. The aims and contents of the two courses are tuned to one another.
groupsClass size
expand_circle_downThe courses are explicitly focused on individual guidance and personal contact with (and among) course participants. For this reason, the number of participants per course is limited to a maximum of 4
The small size of the class makes it easy to switch between plenary instructions and individual guidance. If you don’t fully understand something or need help with a particular skill, you will easily and quickly be assisted by the instructor, because there are just 4 participants in the group, including you!
Similarly, because the instructor is overseeing just the 4 of you in the workshop, he can quickly step in if he sees that you are doing something wrong, even when you are not aware of it yourself.
location_onLocation
expand_circle_downThe courses are offered in Espenaer’s own atelier, located in Het Ambachtslab in Amsterdam-West. The atelier is easy to reach by bike, car, and public transportation. There is ample parking space in front of the building (Paid parking). Participants will receive more detailed directions upon registration.
schoolAbout the instructor
expand_circle_downThe courses are instructed by artisanal furniture maker and founder of Atelier Espenaer, Umut Lucas Espenaer. Umut has over 15 years of experience in woodworking and specializes in artisanal skills, techniques, and hand tools. He originally started woodworking as a hobby before turning it into his trade and is self-taught. He has been offering woodworking courses since 2017 and has had the pleasure of instructing to several hundreds of participants up till now.
For a furniture maker, Umut has a somewhat unusual professional background. He was originally trained as a political scientist and worked as policy officer at the Dutch Ministry of Foreign Affairs and as lecturer at the University of Amsterdam for most of his professional life. He decided to switch careers and pursue his passion, left his career in academia, and founded Atelier Espenaer. He is very passionate about artisanal woodworking and enjoys helping others explore their own creativity.
