Capen" Subject: RV-List: Looking for a machinist I need to have some spacer rings made from .063 aluminum. The spacer goes between the wheel and the upgraded/thicker brake disk and adds a safety gap for my 380-150-5 (15/600-5) tires mounted on stock 5x5 rims. I have an example as I had three made (the first two are installed originally. Someone out there did the first three - I need two more. Anyone interested in doing this - send me a cost estimate. Thanks, Ralph Capen RV6A N822AR @ N06 - discovered the value of a spare tire this weekend...by not having one! Glad I landed at homeplate.... ________________________________ Message 2 _____________________________________ Time: 02:13:41 PM PST US From: Matt Dralle Subject: RV-List: Re: Detaching the Fuel Tank At 01:34 PM 11/28/2011 Monday, you wrote: >--> RV6-List message posted by: George Nielsen > >Does anyone know how I can detach or remove the fuel tanks from the wings?

On the RV-8, there were a lot of bolts. A lot. I can't remember if the -6/-4 have the same arrangement, but it would stand to reason. - Matt "Red Dawg" Dralle RV-8 #82880 N998RV "Ruby Vixen" http://www.mattsrv8.com - Matt's Complete RV-8 Construction Log http://www.mattsrv8.com/Mishap - Landing Mishap Rebuild Log http://www.youtube.com/MattsRV8 - Matt's RV-8 HDTV YouTube Channel Status: 170+ Hours TTSN - Rebuilding Fuselage After Landing Mishap...

There are no rear-baffle-to-spar-bolts on the six wing tank, so you are almost done. There is a bolt at the front and rear on the inboard side. These attach the inboard tank rib to the airplane. In the front it is a bracket, and in the rear it is a tongue fitting in to the fuselage carry through aft spar. You must remove the wing fairing to get to these. Even when you get all those fasteners out there are still some traps. there are a bunch of those screws which are dimpled these dimpled holes do not want to let go of the recessed holes they go in to. you sometimes have to persuade them with a sliding piece of shim material. I use a plastic putty knife to pry the skins up a little to clear the dimples. Further traps include: forgetting to unscrew and disengage the fuel lines and vent lines, and lastly the fuel level sender wire. Good luck. The fun is just beginning. wait til you drill holes in the aft baffle and start cleaning out the pro seal.

Sorry about your fuel leak - I believe the RV-6 has the same fuel tank attachment arrangement as my RV-7A - in addition to removing the screws which attach the tank to the top and bottom of the wing - you must also remove a number of AN-3 bolts which fasten the tank to the main wing spar - the back of the fuel tank is attached to the front of the main wing spar by a series of "Z" brackets which are bolted to the rear of the tank in front of the bracket and to the front of the spar at the rear of the bracket - you can access the bolts at the rear of the brackets by opening the inspection panels on the bottom of the wing - access is not difficult once the inspection panels are removed - the bolt heads will be obvious on the back of the spar - the brackets will stay bolted to the tank as it is removed - Good luck with the leak.
