Thank you for detailing the build of the scarfing fixture. I have read several articles on that style but seeing it in action adds a lot of confidence that it will work. The idea of running the router along the grain is something I would have not thought of until I had planed down the roughness on a number of boards after going across the grain. Thank you again and please have a great week ahead.
I'm building my own boat, using laminated timbers for the framing and keel. This sled will be perfect for making the joins for the laminations. I'm thinking of making a round plate to house the router, I feel this will give more freedom of movement and have less friction when moving it along the sled. Love the channel, and your work. You prove that boat building is an art.
She is coming right alone as you can start to see just how sweet her lines are as the you plank her. That scarfing jig is top notch, I had to scarf plywood sheets to build my jon boat and I an electric plane to cut the scarfs, your way looks a lot more accurate. I like it!
That board puts tension on the board so that when the wood wedge is put in they work in conjunction with each other to hold the board firmly. The wedge forces the board flat to the base of the scarf jig.
@@gary24752 the scarf jig is clamped to the bench. It would be very difficult to get clamps where they would need to be. If it was efficient t to clamp it the clamps would mare the soft cedar. The wedge exerts an even pressure on the board. Many of the scarfs are not at right angle cuts. The wedge is a quick way to get the plank secured quickly a and release it quickly.
Looking for some advice on repairing a broken sailboat mast. I need to patch on about a 4' piece on the bottom. The mast is constructed with spruce using the bird's mouth method. I think some kind of scarf joint would be the strongest, but I'm not sure how to do it for this application. Thoughts? Cheers and thanks in advance!!
please use a push stick when using the circular saw, your fingers don't grow back...at 6.25 + good information otherwise . you can copy the line for the second plank directly from the leading edge of the first one using a 2 " x 1 "block against it and on top of the new piece (new plank clamped on your spacers or ribs less than 2 " from the edge ) using a pencil.no need for a compass etc. The line is ready for cutting when the plank is removed.
Beautiful fit on that broad-strake. Is it or the garboard beveled to fit the adjoining edge? Also, did you use it as a "kinda close" pattern for the port side broad-strake? Thanks, and keep up the beautiful work.
Thomas Russell Yes, it does have a slight bevel. I did include that this time as it was very slight. I will show how to make a rolling bevel on a plank that it’s more pronounced on. Easier for the camera to see. I did use the starboard plank as a pattern for the port side. Thanks!
Curiosity is scarfing stronger then butt plates? Wanna build a 12 and 20 foot jonboat for beaver trapping. I dont like the idea however of an uneven bottom with butt plates every 4 feet. A lot to trip on and alot for gear to get caught on. Worried it might bust the boat with me and all my gear in it.
Hi Gordon, I answer that question in the beginning of E2-E42 Chain Plates & Deck Canvas. Here is a link: ua-cam.com/video/0GVdUPDrfEA/v-deo.html Thanks for watching. Bob
Ummm. You had the scarf joint completed when you cut the 2x6 wedge. Why not just use that system with a fence and a little block plane/sanding? I respect the desire for perfection, but thickened epoxy is very forgiving.

A very nice scarf jig Bob. Great episode and Thanks for sharing!

Thanks Dan.
Bob, your tool making is as much fun to watch as anything. Thank you
Wow, thanks!
The art of boat building is anything but straight forward. Great series. Thanks for taking me along.
That's how I made my scarfing jig back in the the early 1980's. Great job.
Great idea using the plate the router is already mounted to , love it
Your jig is a great solution to the scarfing problem. Boat building is a constant series of problem solving, followed mostly by a lot of sanding.

Bob, you are meticulous and gives great results. Thanks for this series. Its going to be a fine boat.
I like your scarf joint jig. That is a very nice piece of work.
Love your immense attention to detail Bob, you are a true craftsman and talented artist.
Block and bridge. Clever (and obvious once you see it the first time)! Thanks for the video.
Your scarf jig works really well and with the epoxy glue, you get a strong connection without butt blocks. The interior is going to look great.
I caught a glimpse of you on the Acorn to Arabella recap video working on the keel, it was a nice cameo.
Nice work Bob! Love your scarfing jig.
Nice studio you have! Many thanks for your vids!
Nice work Bob.
Wonderful performances. Like it. thank you for your sharing.
Thanks!
Very nice
Why do you have that strip of wood at the front of the jig that raises the board you are planing? Doesn't it keep the board from laying flat?
That board puts tension on the board so that when the wood wedge is put in they work in conjunction with each other to hold the board firmly. The wedge forces the board flat to the base of the scarf jig.
@@TheArtofBoatBuilding But why bother with a wedge? Why not use a c-clamp and keep the board flat.

I’d be happy to help. Send me some images and a description of the event that made the mast break. My email is in the about section of my channel.
What router bit did you use?
1/2 flat bit.
Is it safe to assume that after these two planks it will begin to go a bit faster?
Glen Crandall let’s hope that is true. I’ll but several planks on before the next video.

At least use a push stick when people are watching!
Is there a reason why you didn’t use the plank as the template for the second plank on the other (port) side?
Barry Karow I did check to see how it fit. Which was good. I then used it as a pattern for the port side.
Beautiful fit on that broad-strake. Is it or the garboard beveled to fit the adjoining edge? Also, did you use it as a "kinda close" pattern for the port side broad-strake?

Yankee model 30?

Why use slot hd screws ?? Phillips are quicker, safer, & same price ...
