There are a series of pictures of the engine, no plans at https://www.flickr.com/photos/28865130@N04/albums/72157685361917640/
I can't see that pictures of the engine could be copyrighted unless they are reprints of pictures owned by someone else.

The OP had posted pdf copies of the whole build from the book not photos.

Well i intended building the Wedge engine for a long time, but reading throught the build article, it seems daunting. There was quite a few complex shapes, to me anyway, and i struggled to plan how to machine some parts. Anyway i started and approached each part one by one. I did indeed made some parts a second time. I do not have silver solder facilities, thus the frame and cylinder was soft soldered. I'm not sure if it will stay together if steamed for real. However on air it works quite well. Here is a few pictures of my progress, i tend to forget to take pictures along the build. The paint is Tamiya plastic build kits paint that i have left in my scarp box and it was not even enough. You will see the crankshaft bushes is not pressed in yet, i need to get some more spray paint to redo the frame.

Getting the correct profile radius on the cylinder block part.

This i what the valve block looks like on the frame part of the engine, before it is soldered onto the frame

Here is the copleted part that gets soldered onto the cylinder.

Completed engine, very simple yet a nice looking engine.

It was running on about 18 kPa air.

A splash of paint, some may frown upon, but that is what i had on hand. A lubricator may be in the pipeline to be fitted.

A very nice little engine.
