Hi Lindsay,
I've got information relating to various propellers, which have been obtained from various sources. There is a website which has drawings for quite a few propellers, but I can't remember the URL right now. I have at least one British factory propeller drawing, but it might be a bit too large to get a copy to you, unless I had it copied by a plan printer and posted it to you. The best way would be to try to find the website. I should be able to find the URL for it, but it could take me a while so please feel free to send a reminder at any time!
I made a 1:8 scale Axial propeller for a Hasegawa Fokker triplane, but it was a lot of work! I intend to build a variety of different types of propellers, both full sized and in various scales. The first one is always very difficult, due to the fact that most of the time is taken to construct the patterns, jigs and formers. Once this is achieved it is possible to construct a propeller relatively quickly.
Regards,
David.
