I am building a little cabin and I used a spline to join the middle beams, and I'm very happy with the results, but I'm going to incorporate this join on my next project. Wow.
Love your work, very well explained. I hade done many different designs for the scarf joint. I found one similar to yours but with a rounded corner (inside corner) where will prevent the wood to crack. I see a split crack in the joint (V angle) on yours scarf joint. That is what I'm talking about.
Awesome video BTW! You said in this video "you could NOT use this joint unless it sits over a post". Is there a better scarf joint if you are working on a hobby project and need to lengthen a 3/4 in Thick x 2.5 in. X 40 in solid Pine board and add on 20 in of same species PIne to make it 60 in? I will add that the project I am working on is not a "life or death" situation if it fails or breaks in the future. I "could" go out and by the correct length but I would like to "try" to make this joint because it would be a fun project. Incidentally, it is for my "lovely" neighbor's dog ramp so "Bella" can get up on the bed at night.
There is a specific scarf joint that we use for posts and plenty of scarf joints that we have not used. In the past we have used it in horse barns to introduce pressure treated timber to the bottom of posts. We will absolutely make a video about that joint next!
Question: Do you ever run into a problem where the scarf joint at the point where those pieces are "under squinted" risk causing the mating beam to split in that deep V? Is that a risk?
That absolutely can be a problem if it is cut in a way that exerts too much pressure into that “V”. In other words if the two mortises are too offset, it is possible that they could become overdriven and split that “V”. We have been timber framing for 50 years(this year) and have never seen it in practice, but with poor design, it could be possible
Love that you leave the outtakes in there. Can’t wait to cut one of these!

Top timber framing question answered! Looking forward to learning about "castle scarf joints" for use in posts.
These videos are so fun to record we would love to build out a “joint library”. We’ll keep them coming!
@@ShelterInstitute I BET ALOT TOOK IT A DIFFERENT WAY

"under squinted stop" where my design is rounded to prevent wood stress and possible to crack the timber.
Great explanation . It is a mouthful.
Thank you! It really is
@@ShelterInstitute I can believe he did not right that done so he could read it off. But it makes him look human.
It's a beautiful joint
Truly, one of our favorites!

So, this wouldn't be used on a post, but is there any joint that would be, or is lengthening a post just something to be avoided generally?

Great instruction as always!

Curious how much you offset each mortise in opposite directions to create the wedge?
Complete cut sheets and layout process are included with the full course! Each mortise is 1/8” offset making 1/4” total offset
Would pegging through the tenon be a good idea for a joint like this or would it diminish the value somewhere in the scarf? Thanks! Love your videos
Absolutely
Posts are in compression, beams are in bending, collar ties are in tension. Can a scarfed joint as shown be used without a post??
I am wondering the same thing...
Could this be used for the keel of a boat that is getting tarred and riveted together? Instead of a standard boat scarf?
Please refer me to the video of How to do a joint for posts? Is it a scarf joint?
Excellent
Thank you!
🙌🙌
Thanks for watching!
Yikes say that three times fast. Great explanation.
Thank you! The first step to mastering a scarf joint is learning how to say its name
Over a post,is the top of the cord ,wave
That is why you will only see them by the brace ,in older frames ❤
