Subject: RIB TESTING RESULTS Group, I , like many of you, have been searching for an alternative toSitka for use on the Pietenpol. I have been intrigued by Western Red Cedar ever since seeing some exceptional 4x4's at alocal lumber co. The grade was called "ornamental/ deck" and the grading gave me goose bumps. One of the 8 footers hadperfectly vertical grain the full 8ft. When I ripped it the kerf followed the same growth ring nearly full length. I havetried with no success to get more detailed comparative info. from ForestProducts Laboratory in Madison, WI. Not to be discouraged, I built a ribusing the WRC, 1/16GL-2 3ply and T88. Using the guidelines suggested in AirCamper.org/info/tips andtricks/testing rib strength, I built a test jig that uses controlled spring force vs. bulk weight. I applied the force at theincremental spacing listed. I was very pleased to see the 204# load with no ill effects. I continued to load in 1.4#increments until I ran out of spring travel, at which point the rib sustained a 358# load! I would be interested in hearing fromthose of you have have tested ANY ribs and what pitfalls I might face with using the WRC for ribs. By the way a4x4x8ft. "post" was $20. Two of them will make 90 cap strips.________________________________________________________________________________
