A filleting gun is a specialized caulk gun with replaceable tips to control the flow of sealant. Semco is the primary manufacturer. Here is a link to a video on fillet sealing using a filleting gun.
That's fancy. Thanks for the link.
Doesn't this in effect also seal the center of the rivet? I've seen these on a TV show about a company in WA (IIRC) that rebuilds old camping trailers.
I believe it should seal the rivet but I've found no proof of that. I learned about them from the Airstream forums as they're the best (only) way to do repairs that look original. There's even an entire thread devoted to photos of patches on airstreams. Not that I have looked at it several times...
Gregor, thank you for reminding me how many tools I need but don't have. I now have a used Roper Whitney punch and new Cleco and Pliers kit arriving in the near future. The rivet removal tool is saved on the Northern Tool site waiting for one of their sale flyers to arrive. My riveting projects will hopefully involve mostly setting although to be honest I expect to be in removal mode almost immediately after. After setting a few 1/4" pop rivets I graduated to a pneumatic riveter.
Ha, you're welcome! The thing is I can't think of any tool I've ever bought that I have regretted. Save for cheap tools - I typically regret those right after using them. You'll really love the Roper Whitney punch and they're pretty darn cheap considering how useful they are. Make sure they come with all their dies - you can get replacements but they cost almost as much as a used punch.
Oh, and my rivet shaver came with a pneumatic rivet gun. I have tried it and it's pretty nifty but I haven't "used it in anger" yet. That one seam will be where it becomes useful.
Gregor, are you using sealed pop rivets, or just standard pop rivets? Adding the sealant should be helpful, but I wonder if it reduces the compression? Even if it does, you have every opening sealed pretty tight. In my experience, we'd top seal the rivet, but I don't know that it would be necessary in your instance.
Keep up the great work! When will you buff it out to a mirrored finish?![]()
Blessedly the Avion is anodized and so buffing it is ill advised. I will have to have my patches anodized before I install them so they match but I have dodged the bullet of polishing the trailer.
Word on the airstream forums is that the sealed rivets are a bad idea. The seals prevent the full tightening of the rivet and when the seal dries out the whole thing is loose. I do plan on top sealing the rivets on the roof and the entire seams with Eternabond. It is supposedly the best thing out there for covering the seams.
I'm not quite sure how I have previously missed learning about shaveable rivets, but, I'm not surprised that I learned about them on this thread.
Of course, one never knows with mother nature, but I'd wager it's too early for the rains to move back in to stay for a while, i.e. until next summer...
Yes, thanks to global warming we've seen our fall get pushed back to the end of October. While there will be a reckoning at some point it has made the winters of the PNW far more pleasant and short.
Thanks all for the support. I have some work projects coming up (christmas is in September in the magazine world) but I will update this when I make some more progress.
Gregor
