Great rebuilds going on with Blackflag and 69 Avion! I think we documented the repair of the tub on this thread. We pulled the sides together with clamps and secured angled metal on the corners with a polyurethane sealant, and them held in place with 4 inch SS screws. I was cautioned by Sleepy that the SS and aluminum may have metal to metal issues, so take that into consideration. 69 Avion. As best I understood your post on the cabinet: "The cabinet was real tight when we took it out and the new flooring is thicker, but I also sanded some off of the bottom of the cabinet. We may have to take it all the way out again to sand more off of the bottom." It seems to me that there was a knockout piece that allowed the bottom to be released when it was removed. I note that you have solved the issue, so it probably doesn't matter. By the way, these two restorations are going at warp speed. Congratulations. ![]() |

I insulated that area with blue styrofoam board . Have you done something different or are just not finished with that yet ? Same thing along the base of the dinette and under the frig . I'm just not done with that yet. That will be near the end of the interior work. Ford F-350 4x4 Diesel 1988 Avion Triple Axle Trailer 1969 Avion C-11 Camper |

There was a little 1 x 1 block that held the closet to the floor and more of these blocks that held it to the wall. The wall 1 x 1 blocks were reused. The floor block was replaced with steel 2 x 2 x 1/8" angle iron that is used more for structural reinforcement for the floor along with the weight bearing mount for the stainless steel gray water tank, but it also is used to screw the closet base to. When removing the closet, once all the mounting screws were removed, we had to pull out the top first. It was really tight. My new floor was slightly thicker, but I had to sand a lot more than that thickness to get the closet back in, and the steel reinforcement wasn't the cause of this issue. |

I wish I had thought to place a reinforcing bar at the base of the cabinet. I actually studied the thing for a long time, concerned about the cantilever effect and the gray water holding tank as well. We did place reinforcement behind the wing, connecting the overhang. But still, I don't think you can be careful enough with the issues in the overhang of the coach. Especially the toilet; when we pulled it out, we learned it was just barely hanging there with the minimal support that the factory had built in nearly nonexistent. You guys are giving us inspiration to finish up the restoration. All of the Corian for the countertops are sitting next to the camper. All the appliances are in the workshed. But, its 105 in the shade. |

Well , there are all kinds of frustration . Here I sit taking a break , staring out the window at my Avion , needing nothing at this point . It's 85F , dry , slight breeze ( no bugs ) , nights are mid 60's ,living in the middle of the White Mountain National Forest , and because of one commitment or another I can't get out of Dodge , probably not till the end of July . Pity party over , LOL

About the galvanic corrosion from alu and ss. From what I can find the mass of the aluminum that we are dealing with vs the SS screws it should not be an issue, the description I read said that basically a SS screw in a 6x6 block of Al will do nothing, but an Al screw in a 6x6 block of SS will fall apart in no time at all. Also almost every screw I can think of that I am using can be seen and checked over time with just a glance so it would not be a problem to adjust. Just my research. |

I have done no research, but have what is left of a portable Army Radar Tower. It was built in the late fifties or early sixties. It is all aluminum, and stainless bolts were used. Every bolt I have removed is corroded with a white powder. Some have been so corroded I used a grinder to remove the heads of the bolt. I have removed them from aluminum 1/4" thick and 3/8" thick. Personally, I would be hesitant using a stainless sheet metal screw without some kind of plastic washer. Using stainless nuts and bolts, I would definitely use some kind of antiseze (sp). Did Avion use stainless fasteners when they built the Avions? Wayne |

So what you're saying is that after over 50 years they are still strong and it takes effort to remove them? ![]() I looked at a lot of aircraft and boating forums about this and they all say that the amount of corrosion is very very little, people with SS screws in saltwater aluminum boats for 20-30 years without a problem. Every screw that I removed from a damaged area is rusted and not corroded from this type of reaction. * This post was edited 06/30/12 09:39pm by BlackFlagForge * |

I removed a lot of rusted screws from my 1969 Avion, and it was in AZ. I can't find any aluminum screws so I am using stainless steel screws. I will watch for reactions, but I'll bet it will be like watching chrome bumpers rust.LOL If someone has a better idea, let us know. Carbon steel screws didn't "get it". |
