Title: water tight connecters
Post by: mandolinplucker on January 30, 2008, 12:40:54 PM
I don't have a bus yet so my present project isn't as ambitious as converting a bus but I need some related advise. My 36 ft 5th wheel is too much trouble for a 2 or 3 day bluegrass festival so I acquired and am restoring a 1968 Avion truck camper. The shell is riveted aircraft aluminum. It sat in a field for 15 years that I know of and the caulk around the windows is gone and some of the wood has to be replaced due to moisture and rot. I had to take some of the outside panels off to do the repairs. I can't get to the  inside to buck the rivets. Pop rivets will do the job but after installing one I can blow air through it so I know that water can get in too. Do any of you have any suggestions as to how I can  put this thing back together and keep water out. I had to replace the bed area that hangs over the cab of the truck and had to drill out over 200 rivets now I have to replace them with something. Sheet metal screws with a gasket behind the head would be water tight but I don't know if they would stay tight under stress and vibration.

Olympia Bulbtite rivets are popular with the Airstream restorers and should work fine in an Avion.  www.bylerrivet.com  They are a pop type rivet that seals tight and looks like a bucked rivet once the special tool is used to trim the mandrel down.

With the use of standard pop rivets that leave a hole after setting, there are push in aluminum plugs that make them look like the rivets like on buses.  All you do is to put a dab of silicone sealer on it and push in.  Good Luck, TomC

Shaved head rivets look exactly like bucked rivets & is what Airstream uses to repair the sidding on their trailers. Mine was repaired at the factory with those & you can't tell the new rivets from the original.

To clarify my post further, the Olympia Bulbtite rivets are shavehead rivets.

Kyle, what you have listed will not work.  Those rivet shavers are designed to shave rivets down completely.  The special tool has a curved cutter and won't take the rivets all the way down. 

Airstreams and probably Avions use smaller shaved head rivets than buses generally do.  The shaving tools for the smaller rivets are on Ebay pretty regularly.  The last time I checked I recall the tool was about $200 new.

Some have been known to shave the rivets without the special tool.  I recall than Brian Diehl did not use the special tool.

Since it wouldn't make much sense to throw the tool away when the cutter got dull, I thought the cutter bits were replaceable. How difficult would it be to get the correct cutter bit?

SOME are, not all, so be sure you order the correct thing. Olympia looks to have a great selection.

Kyle, i got my shaver from www.browntool.com it is a 21,000 rpm Sioux  and I was told by a Airstream dealer this was the one to have because the more rpm the better the finshed product

The cutter tool is designed to fit in a drill.  I assume cutter bits are available for replacement, but I personally wouldn't want to run them in a standard rivet shaver.  A standard rivet shaver runs at 20,000 to 30,000 RPM.  I haven't used the shavehead cutting tool yet, but I doubt it has gearing to make it run anywhere near that fast.

Neither the Olympic shavehead rivets nor the cutter tool are particularly inexpensive, but the alternatives of pop rivets or drilling hols in structural steel for a bucking bar didn't appeal to me.

I would be happy if someone knows a less expensive way to shave the shavehead rivets that actually works (Other than a grinder and a steady hand) as I have 1000 to do and would rather not buy a one use tool.  There are two sizes of the tool and the smaller one comes up on Ebay pretty regularly as the smaller rivets are used on Airstream repairs and restorations.

belfert,

Buy one then sell it to another bus-nut. I'm sure others might be interested when your'e finished.

Tom C gave you the right answer. Use plain old pop rivets and push in aluminum plugs/caps.

The regular pop rivets with the plugs are what i used.  they worked well.  I used POP rivet brand, i have learned my lesson on that imported crap.  The caps are call mushroom caps, and while I didn't use the dab of silicone, wish i had thought of that,  i have not had a problem and have had them in place for over an year -- i believe that is more important to get the correct rivet for the right applications -- many different sizes grip ranges, applications, and tooling -- typically if you get all of that right things work well -- the mushroom caps look like buck rivets when completed, just take a small hammer and tap them down -- good luck ...

I have used regular pop rivets on a couple of occasions. Installed the mushroom cap with a dab of silicone and used a plastic hammer to install. I found that a metal hammer left a small dent on the top. It has worked well so far. I also think they look pretty good. I'm cheap, what can I say.... ;D

Paul,  Your not cheap, Your just smart. In case you have to remove it, just drill it out by removing the cap.Very easy and a good job at that.

Thanks Pete.....I do think that if I do many more I will invest in a power gun....The last time I did around 50 my arm was numb.....I know I will have to in the future as I will replace some of the skin that is in bad shape. That is after some RUST repair...That's right, that ugly R word..... ;)

Fun, fun, fun

I did some digging around and calling around and talked to Hanson rivets that I found on the web. Them and a few others have "closed end" rivets. The salesman wanted to know the application and the thickness of the material to be fastened. The rivet goes on with a regular pop rivet tool and the back end is closed and the "nail head" stays in the back of the rivet. He said that ,if the rivet is sized correctly, it is water tight. It has the hole in it like a regular pop rivet so it looks like it would leak but the back of the hole is solid. It won't look original but the cost is 1/3 the shaved heads and I don't have to buy an expensive tool to make them look pretty.
