There's a detailed rib test at Decosta's site.Myself i just glued fake spars 3' in lengthto test rib, (the rib had been accidentlydamaged) I then invered the test rib andspread the fake spars between two sawhorses. Then I proceded to add weightspreading the weight evenly accross the lengthof the test rib untill 533 lbs. had beenloaded, running out of barbells then imoved all the weight to the front sparand 300 lbs on the leading edge 200 lbs'6 inches aft of front spar. I then movedall the weight to the rear spar and was amazed.The test rib was held rigid at sparglue points only and had a hair linefracture in the top cap strip and was missingsome gussets on one side. yet it probablywould of held 900 lb's. If the woodi'm using is of good quality I don'tworry about the strength of the ribsthis was a 23012 airfoil like a Taylor Craft.russel----- Original Message -----________________________________________________________________________________

Mike,Are you referring to the gentleman at Brodhead with the ultralight Pietwanna-be and rib test? If so, I didn't catch his name, but I'm prettysure it wasn't Roger Mann unless he has put on a bit of weight. And hisplane was not one of Roger Mann's Ultra Piet's unless it had been verymuch modified. His test jig basically mounted a rib upside down fromsome stub front and rear spars, then hung weights fairly evenly spacedalong the rib to simulate a distributed air load. I think Wayne Ison(Mini Max designer) did something very similar. You could do the samething, build identical ribs out of spruce and cedar and load them tofailure using the same amount of weight and distribution on each rib. At least that would give you a direct comparison between the twodifferent woods for this application.

The guys name is Roger Mann, His company is RagWing Aviation, and the planeis an UltraPiet.There is also a ragwing buiders listDon't have the link on this machine, but it should be fairly easy to find.Mike-----Original Message-----

Ragwing is in rural South Carolina. They have a nice web site. I don't havethe URL on this PC, but you should be able to find them easily. RagWing isone guy who seems to be prettty prolific with single place designs. He isquite proud of the hands off stability of his Piet lookalike.Mike BellColumba, SCMaiser(at)adena.byu.edu on 08/03/99 07:13:58 PMPlease respond to piet(at)byu.edu @ INTERNETcc:Subject: Pietenpol-List: Re: Closer LookThe guys name is Roger Mann, His company is RagWing Aviation, and the planeis an UltraPiet.There is also a ragwing buiders listDon't have the link on this machine, but it should be fairly easy to find.Mike-----Original Message-----
