This may end the hobby going forward. Most or all of those plan sets were released to the public so guy's could build them in there garage. They were never intended for commercial use. Now going forward if somebody designs an engine he may choose to keep the plans private rather than have them fall into the hands of people who do work like you see in this thread. I know I wont if I ever do it again. I would be pretty pissed off if it were my designs being used as a commercial endevor.
I have been publishing many of my drawings/designs as I get them complete, and have a note on the drawings that they are copyrighted, and for personal non-commercial use only.
Obviously people around the world will do whatever with any plans that they find.
One has to decide whether to release plans or not.
I don't like people using my designs for commercial use, but having the designs vanish into obscurity is less appealing.
I have redrawn some of my dad's designs in CAD, and published those in open-source (free) format.
Had I not gotten access to my dad's engine drawings after his death, those designs would have vanished forever.
Most of the Bernays that can be seen on GrabCad used my drawings, that were derived from my dad's drawings.
My dad's No.21 can also be found on GrabCad.
I must say it is cool to see one's drawings morphed into 3D objects, and appearing on the web.
My intent is to advance the hobby in any way I can, and perhaps raise it to new levels that have never been seen before.
The world has become a very strange place of late.
I am still plan on publishing drawings for everything I build, and posting them for free in open-source non-commercial places around the web.
I posted full drawings for the green twin (the one in my avatar) in the magazine where it was published.
I suspect copies may show up one day for sale; nothing I can do about it; I am still going to build engines and post drawings for them regardless.
It is what it is.
