(Garey Wittich) 3. 12:45 PM - Re: Misplaced Dimple Hole where Skin Stiffener SURFACE contacts the Skin (japhillipsga@aol.com) ________________________________ Message 1 _____________________________________ Time: 11:37:02 AM PST US From: Garey Wittich Subject: RV8-List: Misplaced Dimple Hole where Skin Stiffener SURFACE contacts the Skin Greetings: Found no answer to this in Matronics archieves. While dimpling the Elev Skin accidently punched a hole and made a dimple about 1/8" from the desired location where the Skin Stiffener SURFACE MEETS THE SKIN. (Stiffener was previously drilled / dimpled.) I "gently' flattened the misplaced dimple with minimum thinning of the Skin - very slight dimple remains. Then dimpled the desired rivet hole. The 2 dimples (desired and the flattened undesired dimple) slightly over lap at their outer edges. Took a #49 drill and drilled the undesired dimple hole to relieve MOST of the Skin cracking at the hole edges. Question: Any suggestion on how to prevent possible "future" cracking of the Skin where the undesired dimple is ?? Use RTV to fill the hole from the Bottom Side and Super Fil to cosmetically fill in the Top Side of the Skin ?? (Do not believe RTV can be painted over - otherwise would use RTV on both sides ??) Appreciate suggestions, Garey ________________________________ Message 2 _____________________________________ Time: 11:46:35 AM PST US From: Garey Wittich Subject: RV8-List: Use Miniature Toggle Switches for Mag Grounding ??? Plan to use C&K 7000 Series miniature ( 1/4" size ) "LOCKING Toggle Switches for Mag grounding as Panel space is limited on the RV-8A. Anybody have EXPERIENCE using miniature toggle switches (made by C&K, Alco Switch, etc.) ???? Were they reliable in this application ??? If so, what Mfg / Part # did you use ?? Thanks, Garey Santa Monica, CA (310) 392-1682 ________________________________ Message 3 _____________________________________ Time: 12:45:38 PM PST US Subject: Re: RV8-List: Misplaced Dimple Hole where Skin Stiffener SURFACE contacts the Skin From: japhillipsga@aol.com Garey, sorry you messed up, but it won't be the last. I to have made a few extra holes and dimples. Unless it is structural what I did was install a short flush rivet and let it go. Sometimes you can make a bigger mess attempting to correct a flaw then just to plug and move on. There may be a "perfect" plane out there, but I doubt it. Good Luck, Bill of Georgia RV-8a finishing kit?? -----Original Message----- From: Garey Wittich Sent: Thu, 16 Oct 2008 2:35 pm Subject: RV8-List: Misplaced Dimple Hole where Skin Stiffener SURFACE contacts the Skin Greetings: Found no answer to this in Matronics archieves.
