- In this video I demonstrate to you how to layout an angled mortise and tenon using a traditional Chinese woodworking marking paired with an offset plate. The method is literally foolproof. The offset plate was inspired to me while I was making a 4 leg 8 splay (四腿八叉) style of stool. With the of attachment I am able to layout the mortise on the top surface, the mortise on the bottom, and the tenon using a single set of measurements.
Checkout the links below where I show you how to make a variety of traditional Chinese woodworking tools.

Really great video! Never would’ve figured that out on my own.
Thanks. Glad it was helpful.
I like the ingenuity of those marking gauges.
That’s what I’m talking about!! Just the instruction I was looking for.
First John, it's great to see you making content again! Second what a great tool and simple transfer method.
Man, I am so glad you have been making these tools, projects and posting them online! I have been interested in traditional chinese woodworking for years, there is just so little coming out of there until a year or two ago. Keep up the good work and thanks again for posting all these good things and inspiring me to learn more about them.
Wizard! Thank you for the careful and thorough tutorial.
Glad to see new videos. I love seeing different approaches to the same problem and your Chinese woodworking videos are interesting and a nice perspective.
Elegant creation and modification. Thanks, John.
I can't believe how scarce the videos involving square angled legs are
Thanks!
If you mean "splayed" instead of "square" then glad it was useful.
@@johnzzhu
By "square" i mean (mortise and tenon)😂
Most people i found when making splayed legs they make them round and all they need is a drill and a bevel gauge
Great to see some Chinese woodworking content. Keep it up.
Wood working is wood working; the internet has made it that there are no longer national or regional boundaries for woodworking. It is global woodworking for me.
Fantastic series of videos. Thank you so much for sharing and teaching.
Great video, thank you for some excellent content.
thanks for watching and enjoying it.
Great Stuff!!!!
Thanks John
Thanks for passing on knowledge. Always appreciated.
Ok, I watched your build video for this tool, awesome thanks for sharing it.
I am glad you found the answer that you were looking for. And I appreciate your kinds words and efforts.
Very interesting device you have there John! Thank you for sharing.
Nice video. Now i understand how did it work. That the answer of my question in previous video... thanks John!
No problem.
Love that jig I think im going to try and make one then make some more
stools
Nice video. Cool tool. Looks like a time saver. Mahalo for sharing! : )
Very clever. Nice job.
I love that idea of the offset plate. I'm surprised it doesn't exist on other marking guages, as I could imagine it having a number of uses. I'm guessing you could also have the offset panel permanently attached to the guage with a few nuts and bolts (or wing nuts) and use a drill or screwdriver to expand the offset to the required depth. So, fully seated offset plate for the top, expanded along the bolts for the bottom in your example. The only reason I'm suggesting this, is that I would definitely lose all those nicely made spacers you show!
The marking gauge/off set plate can be used for a variety of projects, up to the each individual to choose how they want to apply any idea. I think in creating an object there is always balances between competing forces. For example, design (taste) vs. function; do you really "need" a corinthian column? How is it better or worse than a plane round/square column?
Similarly, there is a balance between complexity vs. simplicity. So it's up to you how much complexity you want to add to solve whatever problem you might have.
@@johnzzhu I have to admit, I struggle with complexity vs simplicity. I'd spend days thinking out a design in case I've missed some unforeseen minor function!
I figure you must have laid out the shoulders of your leg tenons using the angle block? Thanks for the great video.
I have to admit that I got a little dizzy trying to wrap my head around the gauge. However, you should’ve seen the beam of light when you demonstrated its use.
Glad to hear that. It should be come even better lit if you can make one and use it.
I’m impressed. That is an awesome marking gauge plus your demonstration was very good. Are the cutters repurposed Allen wrenches?
Always appreciate your kind words. Yes they are.
I must have missed the segment where you determined the angle of the tenon shoulders
The marking gauge looks like a bunch of hex keys traumatised by mid life crisis.
I'm gonna try making one ❤
Midlife or wild teenager? I think you're going to like it.
Do you compensate for the diamond effect that the double splay creates or do you just use completely square legs? good video though, and great idea!
That's a great observation. I didn't go through that specifically, because I did not think that level of detail was warranted for this video. But the piece of leg that I used to layout the long of the tenon is already in a diamond shape. The short size difference is so small that I did not account for it specifically, but the chisel usually makes a mortise bigger than it is measured.
@@johnzzhu awesome thank you! I just wasnt sure if it messed with tennon shape making it different than the mortise shape at all. I figured being a small stool there wouldnt be a big enough discrepancy to make much of a difference. Something I couldnt tell from the Chinese masters videos as I dont speak Chinese! Luckily a few of them have english subtitles. Thank you for referencing his videos as well. Its been a struggle to find much on this type of construction in English, so thanks again!!
When you have the top and bottom holes marked, how do you correctly make the angled hole to connect them? Do you make a vertical hole that is within both of them and then remove the remaining spoil by eyeballing the angle?
eyeball the angle, go 1/2 way from each side, they should meet pretty close inside.
John, I like the marking gauge very much. Why didn’t you show the tricky part doing the angled shoulders? That is essential to a good clean fit. Granted, small errors will be out of sight under the stool.
Great point, the angle is 8 degrees, but others may choose a different angle. I wanted to emphasize the ubiquitous aspect of the marking gauge, rather then the angle that I like. I plan to do a detailed video of the full layout of 4 leg 8 splay with 2 stretchers in a future video. I don't think the level of precision should be balanced with the object of the project; so "small" errors is relative, for me on something this size a 1/16 to 1/32 error is not noticeable. Depending on the I can take close up pictures of where the 2 meets and show you that there is "no" error, but again that would distract from the main point. But really appreciate your insight!!
very clever design! simple and sturdy.
Whats the correct way to get a good mortise angled two way?
Hey John, thanks for this demonstration! How do you chisel through the chair at the right angle to not mess up the angle?
You put a line on the out side edge of both angles then chisel half from oneside then from the other side.
@@johnzzhu thanks for the quick reply. I've loved your videos. I hope you are doing well and keep at it!
That's amazing how handy that offset makes your marking :O Is there a reason why both the mortice and the tennon are angled? It seems like it allows for a wider splay on the legs
it don't fit if one is angled the other isn't.
@@johnzzhu I mean more in relation to the technique used here: th-cam.com/video/FXyN1V4IgMg/w-d-xo.html
朱哥总算又发视频了，中间隔了好久啊，都以为你不玩木头了
*sigh* 有想但没时。
Chiselling the journals at an angle is difficult, do you have a way?
There are no secrets to chiseling at an angle, in this case 2 angles, just practice. If you can chisel straight ones well, then angled ones are not much harder.
cut an 8 deg bevel on a board and clamp it to the workpiece and you have a nice guide to help you chisel at the angle
Thanks, how did you measure the angles of the shoulders of the legs?
Trig. Sohcahtoa. Sin(theta)=opposite/ hypotenuse, in a right triangle, knowing 2 variables, you can calculate the 3rd.
@@johnzzhu Thanks
