In Tips From A Shipwright – Episode 23 of the Building Orca series, Lou takes the next step in shaping the legendary hull by building Mold #5.
This episode dives deep into the precision side of boatbuilding, where accuracy on the loft floor translates directly to the final form. Lou walks through how to properly offset your lines to account for planking thickness, ensuring the finished hull lands exactly where it should. From there, he demonstrates how to transfer those lofted lines onto the mold stock, keeping everything fair and true.
You’ll also learn how to:
Read and pull bevel angles directly off the loft floor
Execute progressive bevel cuts for a clean, accurate fit
Assemble and align mold sections while only laying out half the mold—letting symmetry do the rest
Whether you’re a seasoned builder or just getting into traditional methods, this episode breaks down techniques that are fundamental to strong, accurate mold construction.
A big thank you to Arnold Lumber for supplying all the wood that makes these molds possible.
Subscribe and follow along as the Orca continues to take shape—one mold at a time.

Portraits of Power - Mohammad Reza Pahlavi - Politics of Oil
Narrated by Henry Fonda
Mohammad Rezā Shāh Pahlavī (26 October 1919 -- 27 July 1980) was the ruler of Iran (Shah of Iran) from 16 September 1941 until his overthrow by the Iranian Revolution on 11 February 1979. He took the title Shāhanshāh ("Emperor" or "King of Kings") on 26 October 1967. He was the second and last monarch of the House of Pahlavi of the Iranian monarchy.

An overview of seismic base isolation for buildings
Earthquakes are such a challenge in engineering: unpredictable both in time and intensity. But I love this solution of base isolation because it’s so intuitive. It’s something my five-year-old would come up with: just put a suspension system on a building.

In this episode of Tips From A Shipwright, Lou walks through how he modified our new Powermatic 20-inch Bandsaw for precision progressive beveling.
Progressive beveling is a critical step in traditional wooden boatbuilding, and Lou breaks down the setup so it can be applied to any bandsaw — not just a dedicated shipwright’s saw. He explains the angle adjustments, alignment considerations, and workflow needed to achieve consistent, repeatable bevels with accuracy and efficiency.
This demonstration sets the stage for the next major phase of the Orca build, where we’ll begin fabricating molds. Proper bevel preparation now ensures tight fits, clean glue lines, and fair lines down the road.
If you’re interested in boatbuilding, advanced bandsaw setup, or refining your shop processes, this is a detailed, practical walkthrough you won’t want to miss.

Lou from Tips From The Shipwright is stepping out of the boatyard and into the garage to offer something special for sale — his customized 1958 Harley-Davidson Panhead.
In this video, Lou walks you through the entire bike, detailing the motor, frame, custom components, upgrades, and the craftsmanship that makes this classic Panhead stand out. He covers the build history, condition, performance, and the small details that only a true enthusiast would appreciate. If you know vintage Harleys, you know how rare and iconic a ’58 Panhead is — and this one has been thoughtfully customized while keeping the spirit of the original machine alive.
This motorcycle is for sale. Serious inquiries only. If you’re interested, call the phone number below to discuss details.

1991 stand der Bundestag vor einer symbolisch aufgeladenen Grundsatzentscheidung: Sollten Parlament und Regierung dauerhaft in Bonn bleiben oder nach Berlin ziehen? Die Debatte spiegelte die Unsicherheit des frisch vereinigten Deutschlands. Bonn stand für Stabilität, Kontinuität und die Erfolgsgeschichte der alten Bundesrepublik, Berlin für den Bruch, die Last der Geschichte und den Anspruch auf Vollendung der Einheit.
Befürworter Berlins argumentierten, dass ein geeintes Deutschland auch eine gemeinsame Hauptstadt brauche. Berlin sei das sichtbarste Symbol der Überwindung der Teilung und zugleich ein politisches Signal an Ostdeutschland und an Europa. Gegner warnten vor Kosten, Zentralisierung und dem Verlust des bewährten Bonner Modells.
Die Entscheidung fiel am 20. Juni 1991 knapp zugunsten Berlins. Sie war weniger ein Verwaltungsbeschluss als eine Richtungsentscheidung: für historische Konsequenz, für die politische Verortung der Einheit und für einen Neuanfang, der bewusst Risiken in Kauf nahm.

Join Lou from Tips From A Shipwright this Saturday January 31 at 12:00 PM EST for a live update on the progress of lofting Orca. In this livestream, Lou walks through where the lofting process currently stands, what’s been learned so far, and what’s coming next as the build continues to take shape.
We’ll also open things up for a live Q&A with our Patreon supporters, answering questions about Orca, traditional boatbuilding, design decisions, materials, and shop workflow.
Whether you’re following the Orca build closely or just want to talk boats, woodworking, and problem-solving in the shop, jump in and be part of the conversation.
Check out our new merchandise, including our limited run of ORCA Plaques, at our webstore:
https://tipsfromashipwright.com/store-2/
Thanks for watching, and stay tuned for more hands-on boatbuilding!
We want to thank all our supporters and followers for helping us get this far! Keep following us on this journey and check out our website and social feeds for additional content.
In this episode of Building Orca, Lou takes the next critical step in the lofting process by transferring the Orca line drawings to the full-sized loft floor. Working at full scale, he carefully pulls and fairs the offset dimensions from the Profile and Half-Breadth views, checking accuracy and flow as the hull geometry comes to life on the floor.
With these corrected, faired offsets, Lou constructs the true Body Plan—an essential reference that will be used to build the molds for Orca's hull. This is where paper drawings become real geometry, and small inaccuracies get resolved before a single piece of wood is cut.
If you’re interested in traditional boatbuilding, lofting, or understanding how lines plans translate into an actual hull, this episode dives deep into the process.
