Most wooden boat spars aren’t straight tapers — they’re elliptical. And laying one out is way easier than you think. Here’s the simple method traditional boatbuilders use to shape masts, booms, and yards without complicated math. 🌐 nomadboatbuilding.com🛠 Support the builds: patreon.com/nomadboatbuilding #boatbuilding #woodenboat #sailboat #boatbuilder #woodworking #traditionalcraft #diyboat #maritime #sailinglife

Building a wooden sailboat mast, boom, or yard? Here’s how to lay out a proper elliptical spar taper — the traditional shape used on real wooden boats. In this video, Mark from Nomad Boat Building walks you step-by-step through the simple layout method used to create an elliptical taper on wooden spars. Whether your boat plans give you full dimensions or just major and minor diameters, this technique lets you accurately draw and cut a fair, traditional taper using basic tools and a scrap of wood. This is an essential skill for wooden boat builders working on masts, booms, and yards — and it’s much easier than it sounds. 🌐 Website: https://www.nomadboatbuilding.com 📸 Instagram: https://www.instagram.com/nomadboatbuilding 🛠 Support these builds on Patreon: https://www.patreon.com/nomadboatbuilding If these videos help you with your own boat project, consider supporting the channel on Patreon — it helps keep these traditional boatbuilding skills alive and more tutorials coming. ⏱ Chapters: 00:00 Who This Video Is For 00:12 What Is a Spar Taper? 00:27 Why Spars Have Elliptical Tapers 00:33 What Boat Plans May (or May Not) Include 01:23 When You Have to Figure It Out Yourself 01:49 Tools Needed for Layout 02:09 Establishing Reference Lines 02:42 Major vs Minor Diameter 03:02 The Concept of Stretching a Circle 03:21 Dividing the Circle into Equal Parts 04:20 Transferring Measurements to the Spar 05:26 Connecting the Dots for the Elliptical Curve 06:16 Using a Batten to Fair the Line 06:35 Important: One Face of a Spar Is Often Straight 07:27 Real Example from Boat Plans 07:52 Rounding the Spar (Teaser for 7-10-7 Rule) #boatbuilding #woodenboat #sailboatbuilding #traditionalboatbuilding #woodworking #marinemaking #diyboat #boatbuilder #sparmaking #mastbuilding

Most people think wooden boatbuilding requires complicated math. It doesn’t. The 7-10-7 rule is a simple geometric trick that lets you turn square stock into a perfectly rounded spar — quickly, accurately, and without repetitive calculations. Square → Octagon → 16 sides → Round. Simple. Elegant. Reliable. 🌐 nomadboatbuilding.com 🛠 Support the channel: patreon.com/nomadboatbuilding #boatbuilding #woodworking #sparbuilding #handtools #traditionalcraft #geometry #DIY

The 7-10-7 Rule — An Old Boatbuilder’s Trick for Perfectly Rounding a Spar In this episode of Nomad Boatbuilding, I share a simple geometric method that replaces repetitive math when shaping spars by hand. Some people think wooden boat building requires complicated calculations. That can be true when designing boats — but building them is another story. In practice, geometry is often far more useful than math. The 7-10-7 rule is a straightforward way to divide the face of a square into proportional sections (7 units, 10 units, 7 units — 24 in total). By removing the corners at those marks, we quickly create an accurate octagon. Repeat the process and we move from square to octagon to 16 sides… and eventually to a smooth, round spar. In this video I cover: • How the 7-10-7 rule works • Why imperial rulers make scaling easy • Turning square stock into an octagon • Moving from 8 sides to 16 sides • Using (and making) a spar gauge • Applying the method to tapered spars • Why geometry beats repetitive calculation • Using the same principle for moldings, banjo necks, plugs, and even walking sticks This method works for squares, rectangles, trapezoids, and tapered spars. It’s one of those core pieces of traditional boatbuilding knowledge that makes shaping round forms efficient, accurate, and satisfying. 🌐 Website: https://www.nomadboatbuilding.com 📸 Instagram: https://www.instagram.com/nomadboatbuilding 🛠 Support these videos on Patreon: https://www.patreon.com/nomadboatbuilding If you value traditional boatbuilding knowledge and want to help keep these videos coming, consider supporting the channel on Patreon. ⏱ Chapters: 00:00 Introduction — What Is the 7-10-7 Rule? 00:43 Geometry vs Math in Boatbuilding 01:01 Turning Square Stock into an Octagon 01:24 How the 7-10-7 Division Works 03:56 Demonstration on a 6x6 Cross Section 06:24 From Octagon to 16 Sides 08:08 Applying the Rule to Rectangles & Trapezoids 11:17 Using the Rule on a Tapered Spar 12:37 Spar Gauges Explained 14:41 Imperial vs Metric Scaling 16:08 Making an Octagonal Plug for a Hollow Mast 17:38 Planing to the Lines by Hand 18:50 A Simple Tape Trick for Divisions 20:19 Beyond Boatbuilding — Banjos & Walking Sticks 21:14 Why This Method Works So Well #woodenboat #boatbuilding #sparbuilding #woodworking #handtools #traditionalcraft #geometry #DIYwoodworking #NomadBoatBuilding #MarkReuten

What does restoring a 200-year-old Danish barn have to do with wooden boat building? Quite a lot, actually. In this episode, I travel to Denmark to help my friend Mikkel transition his online boatbuilding school into a hands-on learning space. Together, we repair and restore part of an 1800s timber-frame barn using traditional materials and methods — lime mortar, reclaimed bricks, scarf joints, and careful structural thinking. Along the way, we talk about: • Timber frame repairs and structural problem solving • Why lime mortar is better than cement for historic buildings • Reusing original materials whenever possible • How traditional construction mirrors wooden boat restoration • The philosophy of repair vs. replacement • Preserving history while adapting buildings for modern use There’s a strong connection between repairing an old boat and restoring an old building. In both cases, it’s about understanding structure, respecting materials, keeping as much original fabric as possible, and solving puzzles thoughtfully. We also visit the original site where the barn stood before it was moved in 1862, talk about Danish building traditions, and reflect on what it means to keep craft alive across generations. 🌐 Website: https://www.nomadboatbuilding.com 📸 Instagram: https://www.instagram.com/nomadboatbuilding 🛠 Support these videos on Patreon: https://www.patreon.com/nomadboatbuilding If you enjoy traditional craft, timber framing, wooden boats, and thoughtful restoration work, consider supporting the channel on Patreon.

Building a laminated wooden boat transom using a marine plywood core and solid mahogany veneers for maximum strength, stability, and a beautiful bright finish. In this Short from Nomad Boat Building, Mark Reuten shows how combining traditional wooden boat aesthetics with modern epoxy lamination creates a transom that’s durable, repairable, and built to last for decades. Using West System Epoxy, the mahogany veneers are bonded to both sides of the plywood core, then capped with solid wood so no plywood is exposed. This method gives you the stability of plywood and the refinishable surface of solid wood — the best of both worlds in wooden boat construction.

How to Build a Laminated Boat Transom | Plywood Core + Solid Mahogany Veneers | West System Epoxy In this episode of Nomad Boat Building, Mark Reuten walks through the complete process of building a laminated wooden transom for a 15-foot Puget Sound sport fishing boat. This transom combines a marine plywood core with solid mahogany veneers on both faces, creating a structure that is strong, stable, repairable, and beautiful under varnish. Instead of leaving thin plywood face veneers exposed, Mark laminates thick solid wood to the surface. The result? A durable, long-lasting bright-finished transom that can be sanded and refinished many times without risking damage to the core. This method blends modern epoxy construction with a traditional wooden boat appearance. You’ll see the full workflow, including: Selecting and grain-matching mahogany Slip matching vs. book matching veneers Jointing and panel layout Wet-out and bonding with West System Epoxy Thickening epoxy with fillers for structural laminations Clamping strategies for large glue-ups Adding a solid wood transom cap Mark also explains why he prefers laminated construction over epoxy-coated plywood, and how this approach improves long-term serviceability and appearance. This project uses West System 105 Resin with a mix of 205, 206, and 207 hardeners, along with fillers like 405 Filleting Blend, to achieve strong, reliable glue joints for marine use.

In this episode, Mark from Nomad Boat Building travels to Denmark to help his friend Mikkel of Small Boat School—and in their spare time, they take on the restoration of a 200-year-old Danish timber frame barn. Originally relocated in 1862, this historic structure is being carefully repaired and adapted into a future hands-on classroom space. Using a mix of traditional timber framing joinery and practical modern tools, the two work to stabilize leaning walls, replace rotten sill beams, repair posts, and fit new mortise and tenon joints into centuries-old wood. Along the way, they reuse original lime-mortared bricks, discuss historic Scandinavian building terminology, and demonstrate efficient, minimal-intervention repairs that preserve as much original material as possible. Expect half-lap joints, scarf joints, loose tenons, chain mortising, and plenty of problem-solving as they carefully shift and realign parts of the barn’s structure. This series documents the restoration of a historic Danish barn, showing traditional craftsmanship, structural timber repair, and the realities of working on old agricultural buildings. Whether you're into timber framing, historic building restoration, traditional woodworking, or heritage construction, this project offers practical insight and plenty of character. 👉 Learn more about Mikkel’s boatbuilding course at Small Boat School Website: https://www.smallboatschool.com/ 👉 Follow Mark’s work at Nomad Boat Building Website: https://www.nomadboatbuilding.com Instagram: https://www.instagram.com/nomadboatbuilding/ Support these videos with monthly or annual pledges at Patreon: https://www.patreon.com/nomadboatbuilding Or make a one time donation: https://www.paypal.com/paypalme/nomadboatbuilding Topics in this video: • 200-year-old barn restoration • Danish timber frame construction • Traditional mortise and tenon joinery • Half-lap and scarf joints • Reusing historic bricks with lime mortar • Structural sill beam replacement • Timber frame wall realignment • Hand tools and modern power tools in restoration ⏱ Video Chapters 00:00 Introduction – Arriving in Denmark & The Barn Project 00:42 History of the 200-Year-Old Danish Barn 01:35 Stabilizing the Structure with Jacks 02:38 Reusing Old Bricks & Lime Mortar 04:10 Assessing Rot & Wall Movement 04:46 Rebuilding the Sill Beam 05:52 Timber Joinery Repairs Explained 06:35 Lifting and Realigning the Wall 08:46 Freeing the Structure & Adjusting Supports 11:21 Repairing a “Loose Halt” Timber 12:22 Danish Timber Framing Terminology 13:19 Traditional Scarf Joints vs Half-Laps 13:54 Reinstalling Structural Timbers 14:57 Blending Traditional Joinery with Modern Tools 18:56 Corner Repair Progress Update 21:17 Removing a Major Structural Timber 22:29 Lowering Heavy Timber Safely with Ropes 24:04 Fine-Tuning Timber Fit 26:40 Laying Out a New Mortise 29:58 Chain Mortiser in Action 32:43 Cleaning Up Mortises by Hand 35:07 Test Fitting the Timber 36:22 “Barn Sauce” & Workshop Humor 37:34 Driving the Joint Home 40:21 Final Doweling & Woodwork Wrap-Up 40:46 What’s Next – Masonry Work Begins #BarnRestoration #TimberFraming #HistoricRestoration #Woodworking #TraditionalJoinery #DanishBarn #HeritageBuilding #BoatBuilder
