Ryan D. Posted November 6, 2009 Share Posted November 6, 2009 Christmas came early this year. My materials for chapters 4 through 7 arrived today after being on back order for over a month. Most everything seemed to be in good shape, but some of the foam has a few gouges or the edges are kinda pushed in. My biggest concern is that two or three of the pieces of foam have black smudges on them...possibly from greasy hands at the warehouse. Anyone think this will be a problem?

steve Posted November 6, 2009 Share Posted November 6, 2009 pic, would be nice. first guess would be not, you can work around it,or clean it. chapter 4 is seat back and ? bulk heads. it would be hard to mess them up. if the grease is .05 of the part and will only allow 45% bond, so you will lose .000001% so in short you seat back is 120% - .000001 = 119.00001% this math will not work on all parts. but its safe to say your seat back will still fly. remember this.....in 2-10 years your butt will fly this ! so do what feels right to you, not me (i have 10 in my plane i bet) Quote Steve M.

Phil Kriley Posted November 6, 2009 Share Posted November 6, 2009 Wicks or AS&S will send you new material if needed. But small gouges are easily filled with dry micro - post some pics and we can help you. Quote Phil Kriley Cozy #1460 Chapter 13 - nose Right wing done - working on right winglet.

Anyone think this will be a problem? heres a exert from a old CP you mite find fun, Prior to the seminar, Charlie Gray had got hold of a reject canard that we looked at and Burt agreed that it should not be installed on an airplane. We decided to do an informal static load test to destruction. So we called for people weighing about 175 lb. With Burt positioning each person for correct load distribution, we proceeded to try to fail the canard. We got 18 people (not an easy task, very little room!) on it before we finally got a few minor cracks. At this point, Burt calculated we had 11.54 g's on it, and it still would have got the airplane home. It did not fail catastrophically. Someone must have photos of the 18 people on it. We didn't get one, unfortunately. Quote Steve M. Parkins Link to comment Share on other sites More sharing options...
Big Steve Posted November 7, 2009 Share Posted November 7, 2009 Most of the stuff we order for our planes especially the foam is fairly fragile and can take a beating when shipped. The brown box monkeys are pretty tough on stuff. My first order from ACS 3 years ago I was all excited to get started. I recieved a roll of uni glass that looked like someone had thrown a chunk of angle iron at it like a spear. It had a thumb size hole through almost 6 layers of the roll. Of course the package delivery guy was gone when I discoverd this. I built a spar for a fellow builder the urethane foam was broken badly so I cut around it and made it work. Just remember this is not rocket science and sand paper and saws are your friend.
