    Leni - standard Avid caps I think. Actually, I thought all Avid caps were metal?

    I glued in my vent tubes with some old Scotch Weld 2216 that came with my Kitfox project. I had bought a 5 lb kit of Hysol when I rebuilt my Avid MK IV, and the stuff went bad in about a year. The Scotch Weld is at least 20 years old and it still works fine. I wouldn't glue a structrual part with it, but I've glued all sorts of things and it just works fine. Even glued the side rails on a big truck radiator and it's still holding. It doesn't seem to be affected by the gas either. I never had any fuel come out of my vents, but the bottom of the stem just barely goes through the cap. If that end isn't into the fuel how can it suck the fuel up. Also I thought that the idea of the vent tubes facing forward was so air could come into the tanks to give some positive pressure. Maybe I'm not understanding your question correctly??? Take care, Jim Chuk

    PS wish the Scotch Weld wasn't mixed 2 parts to 3, it would be the perfect adhesive if it was 1-1

    PSS should have mentioned, I have the original metal Avid caps.

    I have plastic auto caps with the vent tubes JB welded in. They leak a little when I full tanks but not bad. The issue I have is if you overtighten the caps to the point they click the vent tube breaks loose. I have re glued them a ton of times. It works but far from ideal.

    Was that on Avid tanks? If so, can you find out what cap he used?? I would love to find steel caps I could braze the vents into like the early KF tanks were.

    Friend here got sick of the glue failures too, ended up brazing steel vent tubes to his steel caps.

    What is the world coming to? You mean the trucks now have PLASTIC CAPS? God help us J3 drivers!!!!!!!
    But, couldnt you use the metal tubes bolted thru the plastic caps?
    Maybe look for Chinese sconces with plastic parts?

    I think you may have the metal caps that look like the caps for a PA18 or any of the old pipers. The kit fox caps are like that. These Avid caps use the screw in style caps that are found on the newer trucks.


    Good idea on not running the tube all the way through, that may do the trick. I was just going off the Avid S.B. and making it the way they showed.

    Now that our Govmt is protecting us from "bad air", the auto systems have unvented caps - This is the ones to use - You can buy a plain one with the handle sticking up from the top, or get the nice chome ones that look pretty and cost more, and the new gaskets are OK with ethenol.
    Being somewhat inventive (might say lazy), I looked for a way to have vent tubes ready made, and finally found a cheap substitute for the homemade ones - I got some sconces at Goodwill for $1 each - these are the ones that have the light socket mounted on a 3/8 diameter gooseneck pipe, which has about 3/8 inch threads on each end, and a nut to hold them to the wall plate - If you want a better looking end, then grind the threads off of the end that sticks out - these are about 4 inches tall - guess you could flair the end? If you find ones with the cheap tin nut, then look at places that have lamp parts and buy some better nuts that fit. Use epoxy or Loctite or some kind of sealer to make sure the nut inside the cap stays tight. If you have the caps with the handle, then put the tube off center. You may have room to put a neoprene washer under the nut.
    Or, make your own?

    I used JB weld on my vent tubes,they are vented caps and have a little pin hole on top,I drilled through that hole but not clear thru the whole cap.Thats what Skyraider told me to do. You are still using the vent in the cap with just an extension of the vent hole.I have seen others with the tube clear thru the cap and they told me not to do that.When you turn my caps upside down you don't see the tube on the inside.Randy

    New Years at the Lodge
    Just letting the locals know... We are going to be doing it up right at the Lodge this Newyears. Got a Pacer load or two of fireworks and it will be a great show. The company cant be beat and its a great place to hang out and enjoy a few beverages, catch some Pike, or base out of for flights to Denali or through rainy pass etc. I am planning on hanging out for 5 or 6 days there and enjoying any kind of flying we can do.

    As of this time, there is only a few inches of snow on the runway. The "runway" is on the lake and Dan keeps it packed and groomed. It is around 1500' long and is marked with Spruce bows or black garbage bags on sticks so you can see it really well. As of now, landing there on wheels is not an issue but I always prefer ski's as there are other places we like to fly out to and land at.

    For anyone who has never been there before, it is located on upper fish lake off the Yetna River about 10 miles below Skwentna. It is without a doubt my favorite place on earth. The view and the hosts cant be beat.

    GPS N 61.57.602 W 150.57.839

    Let me know if you are intersted as we have worked out a great rate for the lodge, based on a few factors ( we are flying in all the food etc so they wont have any real expense other than buring the wood and propane and diesel in the generator) but I need to have a pretty accurate head count to make sure we dont run out of anyting, especially adult beverages on newyears eve!

    Gas caps
    I have been through several sets of caps. When I first got this plane, they guy that had been flying it for 250 hrs before me never saw the service bulletin from Avid and never did the mod to put the goose neck vent lines in the gas caps. When I was rebuilding the plane, I did the mod using structural adhesive per the S.B. Since that time, I ahve built 3 different sets of caps using various epoxy's and glues found at auto parts stores for fixing gas tanks etc. None have lasted very long and in short order, they allow the fuel to seep inbetween the aliminum tube and the cap and it vents out across the top of the wing until the fuel level gets below the tubing. Last week when I took off with full tanks, I watched the fuel trailing off the wing for an hour until I burned / leaked enough fuel out of the left tank to get it below the level of the cap sticking into the tank.

    So.... What caps are you guys using, and are you using the goose neck vent tube? What are you using to glue the tubes into the cap? Are you having any issue with fuel leaking out with full tanks?

    70% of the time I dont have full tanks for the shorter local flights. But when I head up to the lodge I top off so I can get there and back and play around a bit while I am there.

    My cowl blanket also overlaps. I use 1/2" weatherstripping between the cowl and windshield. Isn't perfect but pretty good.

  18. EDMO added a post in a topic firewall to cowl seal?   

    The silicone would be my choice - some older planes I have flown had felt there - others had the cowl riveted or screwed tightly to the firewall. Some booby in the FAA decided that since the Ercoupe aluminum cowl overlapped the firewall that a piece of stainless the shape of the rear of the cowling had to be put on the top rear of the firewall - under the aluminum skin of the fuselage - lots of pains that caused for the ones who didnt get it originally.

    I use the permatex moto seal. That is what the local sled shops use for the engine build too. Have not had an issue with it failing... ever.

  20. Av8r3400 added a post in a topic firewall to cowl seal?   

    My flying Kitfox has an "envelope" style firewall insulation cover. The top of it overlaps the edge of the firewall and forms a baffle that keeps the two ares (mostly) sealed from one another.

    I have not decided exactly how I will do my project plane. I am contemplating the use of a strip of flexible silicone engine baffling from Spruce or similar source.

    Rotax 582 Crank Case Seal
    Does any know if rotax has recommended using any other type of case seal since the original recommendation of Loctite 574 when sealing the two crank case halves together.

    What types have any of you used without any failer of the seal.

    Thanks for your input.

    Whats everyone using to seal the gap between the cowl and firewall? I'm undecided on which route to take.

  23. lv2plyguitar added a post in a topic AVID Flyer Belly Cargo Pod   

    You know at this point I do not have a clue. I would call Airdale as Brett may have the original mold. If he does not have the mold then I can go to CAC Plastics and lay out a proposal for him to make a mold with a minium number of orders. I think the original cost of the pod was 350 to 500.

    So, I think our first stop may be Airdale and then pursue having a form made in Alaska.

    Folding is not a real priority. I'll make longer prop rods for the tail. Yes it will be wider than 8', but, not a priority.

    Wait until you see what I'm planning for the tail...

    Make sure that dorsal doesnt interfere with flaperon counterbalance weights when folding wings.
