Big day today. I removed the first vent and did a rough installment of the new Fantastic Fan. Process? First, drill out about 50 rivets that held the old vent in place. Truth be told, the old vent was a superior piece of work back in the day, but the motor was shot, it leaked, the lid was über-repaired. In short, 45 years later, it was a mess. Oh, and did I mention an absurd amount of ancient vulkem? The only way to remove the stuff is with a scraper and heat gun. And patience. The original gasket (or what was left of it—we'll let the archeologists argue that one) was paper with an adhesive. Clearly, the makers of these trailers weren't expecting them to last as they have. Hence the later addition of butyl tape, more vulkem, more silicon (and please, if you ever work on an Airstream, resist the urge to use silicon. Even after decades, it simply doesn't want to come off).
The process of installation was simple. Use the foam gasket provided, mark the inner diameter of the hole, cut with shears, place fan in hole and use a few screws to keep it in place until spring thaw. I'm unable to do any caulking as temperatures are too low during the day. So, I'm working ahead.
Marlene figures this installation marks a turning point in the renovation process. Me? Not sure. I see this whole experience as a process: I have no end date, no deadlines, and no idea when it'll be completed. One thing I do know: if I were working full-time, working on the AS would potentially become tedious because it takes a LOOOOOOONG time. Putting in this fan took a couple of hours.
Two more to go.
By the way, don't always believe what you read on the internet (how's that for a revelation....). A fellow suggested, in one video I watched, to use butyl tape around the edges. Upon reading the installation instructions, the manufacturer specifically mentioned not using butyl tape. I think they're worried it might stress and later fracture the plastic flange (that is screwed onto the roof). The original AS vent was entirely aluminum—butyl tape would have been the perfect solution. No problem. I have many tubes of Sikaflex 221, just begging to be used. Come springtime.
Hole before cutting for new fan. Notice I'm standing on ribs. |
Voila! New look inside. Sky light and fan. |
Out with the old, in with the new. And no, I'm not referring to dialectical antagonism. |
Yep couple of hours sounds about right. This may sound crazy and it is messy but you can cut your time in half by using a flappy wheel on a 4 1/2 inch grinder to remove most of the old Vulkem and even the rivet head
ReplyDeleteBut I am privy to an itinerary: after Marlene's and my visit to Judy and Ian, you absolutely need to drive east to Washington DC. I could fly out and meet you there.......
