Just a note on something that might not have been that clear in the video. The setting up of the saws using the bevel gauge is referring to making the cuts required to make the jig. When cutting the scarf joint your saw should be set at 90 degrees. I hope that makes sense.
This really is the best way to make a scarf. I can't believe how many videos I see about router scarf joints or even hand planed joints. The only way to scarf plywood is the circular saw method. It is precise imperfect. Excellent video. This is exactly how I do it.
I certainly like this method. Not everyone agrees but I find it really quick and it certainly gets things close enough to then be dressed up with a hand plane 👍
Thanks. I’m an old butt block dude. But for this present build, the NOT QUITE the world class cruiser I’m always going to build, I’ve been eyeballing home made scarfing jigs. All SEEM so simple, but I think it’s in the skill of the scarfer. One thing about me and jigs. I’ll spend several hours fashioning and practicing, then, 2 - 4 cuts, and done. Forever.
That's often the case with jigs, they take time to build and then the job is done in minutes. Worth it in my opinion though. Butt blocks are pretty good in most instances but you will nearly always see seams crack in the finish at some stage down the line.
Make sure you have a plywood that has a thick vaneer layer. Depending on how much you have to clean up after gluing the joint. You may end up sanding through it as i did. I used a birch plywood that had a very thin vaneer. Like comically thin lol. I ended up using that side for the interior as i sanded too deep.
Great way to scarf with an easy to build jig. I just built one and it will work great for 1/4" ply but the scarf is too deep using a 10:1 on 1/2" ply for a circular saw. Open to any suggestions on how to go about scarfing 1/2"ply with a set up like this. Is 5:1 adequate? Cheers.
Excellent setup (and results!), Dan. Thanks so much for sharing your scarfing method and jig,, which looks safer/more secure than the popular WEST SYSTEM 875 Scarfing attachment for circular saws.
Hi Dan. Thank you so much for making this video. I know a few of us showed an interest in finding out more after you showed the technique on another video. It looks like such an easy, yet flexible method. Do you have any recommendations regarding saw blades when using this method to give the best finish on ply?
No problem, glad you enjoyed it! My biggest recommendation for a saw blade really is a sharp one. A higher tpi blade may give you a slightly better finish but not by much I wouldn't think.
Nice and fast method, needs some preparation of course with the jig and doesn't pay off for a single scarf joint. Would be interesting to see the joint after varnishing. Often the edges look quite bunked off on planer made ones. What size of blade where you using? Also in order to maintain a sharp edge on the top layer it would be great to develop a method to cut a Z-scarf joint. The method shown here is limited to a certain thickness of ply depending on the saw blade though.
Really only good for very thin plywood. Even a 3/8" thick plywood at 10 to 1 scarf requires a cut 3-3/4 inches wide, but the maximum depth of cut on most circular saw blades is 3 inches. A minimum 8 to 1 scarf would just get by with a 3 inch blade depth but not for anything thicker than 3/8 inches.
Dude your mouth sounds (during speaking), you've got to do something about that. Move the mic further away. You sound like your chewing gum or swishing water around. Makes it really touch to watch. Its just liquid sounds and its gross, I imagine may think that. Fix it and get more subs.

I've always been a router and jig kinda guy for my scarfs.
But then again, im usually scarfing thicker materials and rarely ply.
You have no idea how happy this. Makes me
😁
Dan thank you for explaining how to make the jig. Very valuable tip. God bless you.
No problem Fernando, glad you found it helpful 👍
Fantastic video!
Nice technique thanks for sharing Dan.
Dan this video is phenomenal! Thanks for sharing this technique and jig. I’m going to have to try this out. Thanks again.
Thanks Robert, glad to hear you liked it!
Fantastic explanation, best I have seen!
Thank you
Thanks - always good stuff
Thanks I just finished building my jig based on your design. Ill be scarfing a bunch off cuts ive been piling up to make useful things now!
Brilliant, you'll be looking for things to scarf now 😃
You do outstanding work Dan
Thanks Steve!
Great video! Thanks for sharing.

I show the process for cutting a stepped scarf joint, used for varnished areas in this video: ruclips.net/video/fxdTGRys4GU/видео.html
Often wondered about trying it this way
I find it the most straight forward. Once you've got the jig made the cuts are very quick.
