A Perfect Recreation of a Critical Part, Reborn with Modern Precision.
Born from a blend of historical reverence and 21st-century technology, this is the part that Rumely restorers have been waiting for. We understand that finding a perfect, uncracked original two-leg handhole frog can be nearly impossible. That's why we've gone to extraordinary lengths to create a reproduction that isn't just a replacement—it's an upgrade.
The process began by taking a flawless original frog and capturing its every detail using high-precision 3D scanning. This digital blueprint was then used to 3D print a perfect master pattern for creating a new sand-casting mold. The result is a faithful recreation that captures the exact form and fit of the factory original.
Instead of standard cast iron, we chose to cast this essential part in high-strength Ductile Iron. This modern material offers significantly greater strength and ductility (resistance to cracking) than the original gray iron, providing an enhanced margin of safety for your boiler under pressure. This frog (or crab/yoke) will apply the even, secure pressure needed for a steam-tight seal, ensuring your engine can be operated with confidence.
This isn't just a part; it's a solution, meticulously engineered by fellow enthusiasts to keep these magnificent machines running for generations to come.
