Cygnet Royal

by Edgar T. Westbury
 

Westbury's Cygnet Royal, a 3 cylinder radial steam engine was

conceived in 1962 as an experimental crossover between steam and IC

build techniques. It was designed as a marine engine for use behind a

flash steam generator, withstanding high pressure (80psi and upwards)

and running at high speed (typically 3,000rpm +). In many ways, with its

in-line orbital distribution valve, it behaves as a 2 stroke IC engine but

running much more smoothly.

Removing Supports

I think this is pretty straightforward so I didn't had any photos for removing supports.
Simply pull all the supports you find. Poke any hole with a point tool that might be covered with debries.

Tools I used:
- Needle-nose pliers
- Craft Knife

- Skiving Knife
- Pokey tools

Assembly

Congratulations! You did it!

One last tip. Add a few drops of Sewing Machine Oil (or any other oil) to make everything lubricated
