Documenting a the creation of a Hawaiian coach trollycar

by • March 31, 2016 • No Comments

Creating a scale adaptation is frequently an dedicated act of love. Take Shapeways community member rkapuaala. For over ten years, he’s been working on a adaptation of a coach 64 trolley car and sharing the system
in our forums
. We’ve favored being along for the ride and learning of his method of combining 3D printing with railroad adaptationing techniques to solve challenging problems at scale.

Similar to this create challenge he shared in the forum: “This is as far as I’ve gotten to date with this wooden adaptation. Everything on this adaptation is scratch created via combinations of wood, brass, resin and polystyrene. That comes with the trucks. I stalled on this project mainly for the reason
of the ornate railing.”

This is the railing, as seen on the original trolley car:

Due to the complexity of the create, he decided to 3D print the railings in Strong and Flexible plastic and paint them afterwards.

“As you can see of the render above,” he wrote in the forum, “I did them in 3D which
allows for me to work in 1:1 scale and explode additional details to microscopic levels if I want. Not to mention which
I can manufacture repetitive parts and copy them over and over again.”

When the 3D printed rails of Shapeways arrived, they fit well with the trolley:

“I spent a lot of time cleaning up the railing additional detail and was rewarded. The additional detail emerged at a lower place the white powder which
caked the print. This is the initially coat of paint. I’m not going to use primer for the reason
I do not want to loose any additional detail on the railing. Now I’m confident my additional additional detailed 7/8ths scale adaptation can print out.”

We can’t wait to see what he challenge he posts, and solves, upcoming. You can find this thread (and additional) here. In addition check out rkpuaala’s work in his shop and follow him him here. For additional scale adaptation trains store an eye out the blog and social media. I’ll be at the Okay Scale Model Train Expo in Danvers Massachusetts this weekend.
