Ogle makes big waves with model Royal Navy vessel

A scale model of an autonomous Royal Navy vessel was hailed as one of the best examples of its kind by the team behind its creation.

Ogle Models was asked to create a detailed and intricate 500mm model of the RNMB Harrier by German-based ATLAS ELECTRONIK, the company that had developed the full-size version.

Philip Martin, Director at the Herts-based model and prototype company, said: “We were very happy with the result of this model. Every time we build a model of this scale, we hone our skills that little bit more.

“Myself, and the team involved with the model, believe it is among our best and most complete work of this type.”

ATLAS delivered the 11m full-size vessel to HM Naval Base Clyde in 2020. Using cutting-edge technology, the boat has the ability to survey the seabed and look for mines or other destructive threats. The company approached Ogle to build a scale model that could travel the world to demonstrate the company’s capabilities.

Because of its complexity, a range of processes were used, including CNC machining and SLA 3D printing, as well as some traditional model making and spray finishing. High density tooling board was used on a CNC machine for the main hull.

“It was important we had a strong and stable structure as a starting point for mounting on a display stand – as well as being able to attach the 3D printed elements. We also CNC machined the windows, window frames and parts of the wheelhouse interior.”

Traditional hand skills were used too; the handrails and whip antennae were created from soldered brass tubing.

“It was an intricate part of the build, but our talented team came into their own.”

SLA printing was used for the most detailed parts of the build, including the wheelhouse roof, main aerial assembly, outboard motors, cleats and tie-down points and the seats. The final assembly involved bonding all the different elements together and fixing it to a mount. With the model destined to be exhibited around the world, a specialist flight case was ordered to keep it safely packaged on its many trips.

Because of the size, we had to take extra care when simplifying the details for printing as we didn’t want to take away any of the intricacy of the model. Having worked with ATLAS previously, the client knew we had the knowledge and experience to deliver a model that retained all its fine detail.”
