Title: Joe Ott Book from 1931
Post by Down hill on Jun 4th, 2018 at 9:26pm
Joe Ott (https://www.modelaircraft.org/files/OttJoe.pdf).
His book. Model Airplanes Building and Flying
His publisher. The Goodheart-Willcox Company, Inc. They are still in Chicago. They granted permission to scan and post this book.
History of Model Aircraft. That's the name of this forum. They welcomed the opportunity to post the scans of Joe Ott's book.
For this project we will try to regularly post the scans as if we were building a book, not unlike the model builds you see elsewhere.
We will start this 350+ page project with the title page.

Thanks for the work Downhill. It is possible with a bit of work to reduce the scans in size without much loss of readability, such as the attached zip file with jpegs of the pages you posted.

Thanks for the suggestion, pb_guy. I went back in and changed all of the pdf files into jpegs. MUCH smaller.

When you say "Open" what exactly are you trying to do.  When you place your cursor over the page does your cursor change showing you can select this page or are you right clicking on the page?  I was able to "left" click on it and it showed a bit larger page.  This is not PDF files so clicking on it won't open a new PDF box.

Guys,

     While the text is readable for the most part, the pages with plans have dimensions that are not readable. I will start adding PDF files of those pages so that enlargements will be possible. Just hang with me here.

I'm using Windows.
I'm right clicking on the image and selecting 'open link in a new tab'
I'm having the same thing happen with the image for 112-113.

     Created on an old MacBook Air. I will try to fire up an even older Windows machine and check out the view there. If you are having problems viewing these you must be having problems with other pictures posted here.
     I am scanning the pages directly into PhotoShop, cropping and rotating the image, resizing it to 144 DPI and saving it as a really small .jpg. This is the same thing I do for all old prints.

Nice material, but I have a question. What is the size of a book page? Scan sizes are all over the map.

     I have not been close to a computer for several days now. It has been pleasant playing with my grandchildren while at a lake in Northern Wisconsin. Therefore, this late response.

     The physical size of the two page scan is about 8.5 X 11. I will measure it when I start the last series of scans and give you the exact size. I scan, crop and rotate in an effort to make the book readable. Sorry that the sizes are all over the place. With more work I could certainly make an exact copy, but my intention was to just let the S&T family enjoy an old text written by one of the early notables, Joseph S. Ott.

Greatly appreciated, Down hill. I do book scanning myself and I know how tedious it can be. Thanks for sticking with it.

I sympathize with your issues scanning a book, been there, done that. You have indeed enriched our libraries with an old and useful book. My intend is to tidy up your scans and size the pages to approximately the original height. Knowing your images are Letter size is sufficient. I don't intend to repost your work. What else do you have in your library? My contribution to the modelling database was a FF Fieseler Storch with building manual on Hip Pocket Aeronautics.

How far back does the twin pusher go (originate)? I think I once saw a photo from 1927.

FINALLY !!    The final page.   I hope you enjoyed reading the book. Do more research and find other Joe Ott contributions. Many of his designs are found on the internet these days. When I realize how long it took to write this text along with all of the drawings, scanning it onto this site for everyone is the least I could do.

Final page is Chapter 41   338

Thank you Down hill for your dedication to this project to bring it to completion, and for all the work involved in scanning and putting everything together, and keeping it all straight.

pb_guy,

     Thanks for the comment. Now perhaps someone out there will get inspiration from the book and build that huge compressed air engine powered plane. The search for this book lead to finding another book about compressed air engines for model aircraft by Bert Pond. He called it EXPANSION ENGINE POWERED MODEL AIRCRAFT. You can read more about him and Joe Ott at the AMA history site.

I think that the first CO2 motors appeared in the 1940's and it kind of put the kibosh on compressed air engines. It probably reduced the weight that had to be carried by a larger aircraft.
