    Thanks, I had this in my computer years ago and had a virus that took several documents including this one.

    No Problem. It was Autodidact's idea and a good one. Within two months we are going to have a digital library started here on HBA. Some pubs will be downloadable and some as web links to where you can read or download them.

    OUCH!!
    I just read the part pertaining to plywood covered 2 spar shell wings....my head hurts!
    If I read that correctly, the admission of difficulty getting good calculations for loads require the designer to gain considerable experience before reliable structures and records thereof can be obtained!!
    That sounds like building wings and testing to distruction, measure and repeat, & again & again....
    This is not comforting. I've been planning to build another plane after completing my RV-8. This plane being a steel tube fuse, wood wing RV-8 type tandem low wing monoplane. Think Golden Age Classic.
    This kind of wing must have typically been imperically designed in a series by an individual, like an Al Mooney or the team that designed the Lockheed Vega.

    I am building my second wood wing. The first project was an acro monoplane and the wing was built with Jon Staudacher. This project is a small STOL strut plane for the Idaho backcountry. Using Marske's template I have calculated the spar caps (spruce) and Graphlite rods. The issue is the spar web for the I beam spar. There will be 4 caps with the rods set in and glued to both sides of the web, top and bottom. Using Tom Rhodes approach I calculate the shear to be 470 lb/sq inch. Is there any data on shear values of modern plywood? The seller LL Johnson can't tell me. I have looked at ANC-18 and half inch Sapele and probably 3/8 Birch are more than adequate. I will use 45 degree and scarf them up. I am looking for test data. I can make samples and run tests if I have to.

    Hi everybody!

    Many thanks to Jman and 4trade for their links to these excellent documents. I don't know how things are running in US regarding wood and fabric ultralights, but here in France, this kind of construction appears rather rare, with some exception. Have a look here:

    http://fms7259.e-monsite.com/

    That web site, which is written both in English and French, is extremely detailed in a very innovative way. The author reports all the problems and difficulties he faces and the solutions he found. Furthermore, his approach is extremely traditional and simple, oriented to the best trade-off between safety and cost. The ULM under construction is very affordable. It's a must see!+

    Enjoy your respective projects. Best regards!

    I think they are talking about the one Jake mentioned in Post 3. It would seem a vast undertaking on what is mostly volunteer effort. Juct look at the work that Jarno has put together in the 'Composite' sticky here: https://www.homebuiltairplanes.com/forums/composites/8888-read-first-composites-faq.html
    As with everything worthwhile, these things take time and resources that are difficult to find and or expensive.
    Just my 2 cents worth.
