aviatoreb Posted October 28, 2017 Report Posted October 28, 2017 1 hour ago, M20Doc said: Corrosion free! No.... Well I don't know about the 787, but... I had a Diamond DA40 and...it developed corrosion in the wing! There is a mesh work inside the wing, underneath the layers of carbon to wick static electricity. And they used a cheap hardware that has cheap screws that are visible on the outside. And dissimilar metals...which became a conduit for corrosion. So bubbles developed underneath the paint and the only cure is to "scarf" (the term the factory used) the carbon layers and lay-up some new material. My repair was caught early and cost roughly 2k for a patch the size of my hand, but reading in that forum I saw some people were being hit with 10 and 20k jobs! So replacing a corroded piece of hardware costs 10 times as much if it is buried underneath the carbon. Quote
BKlott Posted October 28, 2017 Report Posted October 28, 2017 That is a pretty nice ride. Of course, it helps when somebody else is footing the bill. Quote
carusoam Posted October 29, 2017 Report Posted October 29, 2017 Scarving is mechanical process to remove thin layers of a material. A lathe is a typical scarving process... as is a thickness planer.... A small version of the thickness planer is just a plane... Using a plane to scarve off thin layers of your plane's surfaces can get pretty expensive... Taking it to the Corvette shop wouldn't cost nearly as much. For some reason known.... A scarved polymer product that we are most familiar with is Teflon tape. Teflon tape starts out as a giant roll, that gets scarved down and slit to width at the same time. Sometimes the word skived is used... scarfed scarved skived All the same process of using a plane to remove thin layers. Except, the focus is often on the removed layers in place of what is left behind... +1 on that awesome plane's awesome HP to weight ratio... Best regards, -a- 2 Quote
