The second MasterClass session of the season dives into the art and precision of laser-cut model airplane kits, featuring returning guest Mark Lanman from Old School Model Works (OSMW). Josh and Brian welcome viewers, answer questions, and explore the process behind designing, engineering, and building balsa kits with both craftsmanship and accuracy.
Inside Old School Model Works: Design, Cutting & Craftsmanship
Mark shares the story behind OSMW, explaining that the company is a small, hands-on operation where he and his wife design, laser cut, package, and ship every kit. Using a 90-watt CO₂ laser, Mark ensures that parts are cut cleanly, accurately, and consistently (6:39). His kits serve a niche long abandoned by larger manufacturers, focusing on traditional balsa models in popular glow sizes.
When choosing new kits to produce, the most significant factor is copyright (7:58). Many classic plans are still protected, preventing legal reproduction. He also notes that some kits require cowls, canopies, or wheel pants—parts that are not always available to produce in-house (8:40). Customer requests influence future releases, and Mark keeps a running wish list (9:56).
OSMW enhances the builder experience with both printed manuals and high-resolution digital photo manuals accessible online (16:40). These allow builders to zoom in on assembly steps for unmatched clarity.
Laser Cutting Quality: Why Clean Edges Matter
One of the most valuable lessons Mark shares is the importance of proper laser cutting. Burnt, charred edges—common in low-quality kits—prevent adhesives from bonding and can affect covering adhesion. Mark demonstrates the difference between scorched and clean wood edges, showing that his kits typically require no edge sanding for glue ups or coverings (23:52–27:11).
Adhesives: CA vs. Aliphatic Glue
Mark prefers CA glue for prototyping and speed, while Josh often chooses aliphatic glues like Titebond for slower cure times that allow repositioning (30:30). The episode reinforces that each adhesive has its place and that builders should choose based on the task.
For hinge installation in future builds, the team recommends DU-BRO CA Hinges, known for their strength and clean installation:
Giveaways & Hobby Trivia
The episode features two giveaways:
-
The first trivia question: What was the first commercially available proportional RC system?
The answer: Space Control—with the winner receiving a laser-cut engine ornament. -
The second: Who designed the models for the 1966 film “The Battle of Britain”?
The answer: Dave Platt. Winners received DU-BRO sanding bars, a favorite shaping tool among the hosts.
Essential Building Tools (Featuring DU-BRO Favorites)
Josh and Mark run through their must-have tools for any builder:
1. DU-BRO Sanding Bars
Perfect for shaping airfoils, smoothing parts, and maintaining flat edges.
2. DU-BRO T-Pins
Reliable for holding parts securely to plans without wandering.
3. DU-BRO Canopy Scissors
Ideal for trimming canopies, curved plastics, and delicate contour cuts.
Additional essential tools discussed include Japanese saws, razor saws, cutting mats, hobby knives, straight edges, and the 90° laser-cut triangle included with every OSMW kit.
Craftsmanship Meets Precision
This MasterClass episode blends nostalgia, precision engineering, and smart building practices. With Mark’s insight into laser cutting, Josh’s deep experience in adhesives and tools, and DU-BRO’s reliable workshop staples, builders gain everything they need to approach their next kit with confidence. Whether you're constructing your first Minuette or tackling scratch-built warbirds, this session celebrates the craftsmanship at the heart of balsa modeling.
