We compile images of wood jointing techniques of the Japanese carpenter with golden hands in the woodwork village. They will appeal to you from the first time. To see more you visit the author’s instagram account here (@dylaniwakuni) or the author’s youtube channel (Dylan Iwakuni).
#1. Sumidome Hozo Sashi: A corner joint used in the floor sills of houses.
The actual one would have wedges on the tenon and a post coming directly above it. When fully assembled, only the outside miters will remain visible, hiding most of the joint.
This joinery was “complicated” to make. Not the most difficult in terms of technicalities but it has numerous little details which made it slight troublesome to make.
The most difficult part for me was probably assessing the joinery and figuring out the order of making and marking the lines. When you cut off one part, the lines on that piece are completely gone. If you remove certain parts without much thought, you risk losing important lines, making it difficult to remark and cause inconsistencies.
I feel a big part of joinery making comes down to the ability to visualise the joinery. When marking the lines, most times you can only reference off 2D drawings and/or pictures. Observing this and fully visualising the joinery to understand what lines need to be drawn. When cutting, you need to visualise the completed shape in order to understand the necessary steps and know where to remove.
This comes from experience making numerous joints. I remember when I started out, I had difficulty visualising the final form from the marked lines.
This lead me to guessing and over cutting certain cuts, carelessly removing important lines, which in turn ended up wasting time.
But all this experience has helped me visualise and understand the importance of lines and correct cutting order. If you’re interested in learning more about marking lines, I may consider doing a live session on it. Let me know if your interested.
Also, if you’d like to learn hands-on the basics of marking lines and cutting joineries, I’ll be doing an online class next month. Details and more @dylaniwakuni
#2. Making some joinery samples.
This is a joinery used in the corners for fine furniture. The pin is designed to pull the materials tight together.
I haven’t made these kind of mitre joints for a while so it felt good making this joint. Making it function properly and getting the mitres to touch flat is always the hard part.
I hope to do an online class on this joinery in October. More details to come soon. Stay tuned!By @dylaniwakuni
