Can you tell me what you used for insulation, where you found it etc. Dennis Thomas ________________________________ Message 2 _____________________________________ Time: 11:39:24 PM PST US From: Leland Subject: Re: RV9-List: Firewall Forward Odds and Ends --> RV9-List message posted by: Leland Dale, my carb heat cable has an OD of 0.19" and the throttle and mixture cables are 0.27". I have a fixed pitch prop so don't have that cable. I am waiting for the Spruce feedthroughs. Here are some recent comments on those feedthroughs from the a post on the Yahoo RV7 list: a) They have a weird shape (12-sided) that requires two large [crescent] wrenches to tighten them (at least when tightening the body on the firewall). Would have been better in my opinion if they were just plain old hex shaped. Still easier than other styles, though. b) They require an odd size...1.15" hole. I guess that's a standard for 3/4" conduit or something. Anyway, I used a 1.125" Greenlee knockout punch (also from Spruce: http://www.aircraftspruce.com/catalog/topages/knockout2.php) and then enlarged the hole just a tiny bit with a 1/2" sanding drum on a Dremel tool. Or just use the right size punch in the first place... 8 ) c) Aircraft Spruce doesn't *really* stock them. It usually takes a few weeks to get 'em in. Other than that, I'm happy with my choice so far.
