Help,

We recently purchased a 2004, 19’ C-Dory and notice that there is a rivet missing in the right rear side panel.

I’ve looked everywhere I know and can’t find anything even close.

Looks like 9/16” diameter, 1/4” hole and estimating with 2 panels thick would need 1/2” or more long.

I’m hoping one of the C-Brats has one of these laying around or actually knows where one can be purchased.

Yes, I have an alternate plan, but it would be nice to replace it with the same rivet as the others.

Please advise.

Regards,

Ron Fisher

Might try a snowmobile shop.
 
Ron,
Give Triton Marine a call. Worth a try, they just might have one lying around somewhere.
 
When they pop I always used a small stainless screw. They work better and you really gotta look to notice a difference.
 
I'm not sure exactly where that rivet goes or connects, to be more precise. I do know that on Journey On the cabin molding is fastened to the hull with those pop rivets. They're aluminum, as you said, and the heads broke off at least in our boat. Or maybe, the installer screwed up. Anyway, I found a leak under the rub strip and then noticed several broken rivets.

First, we can discuss using aluminum rivets is such a critical area, but that's what they did, and I thought that it would be nice to replace it with something a wee bit more durable. So I got several round head stainless machine screws, with lock nuts and used them in place of the broken rivets. Luckily, I could get at both sides. I felt this was a better solution than replacing such a critical fastener with another aluminum item which had failed.

I checked most of the rivets used around the hull to deck joint by pulling out the rub rail and the forward ones seemed all right. I also hoped that they had used a layer of something like 3M 5200 between the hull and cabin joint, though I don't know.

This may be more than you wanted to know, but there you are.

Marty,

I can't quite figure out what is behind the panel/s, however all the controls and wiring run through a tube, so I don't think a screw would run into anything.

I repair gelcoat all the time, so the hole could easily be made smaller, it's about 1/4" diameter now.

So thank you everyone for the suggestions, I have e-mailed Triton and a rivet company and if nothing surfaces, I will follow your suggestion/s and use a screw.

Thank you again.

Ron Fisher
 
Hello from Iowa,

Our guy "Todd", that heads up our shop, also builds Modified Stock Cars.

The large head pop rivets that I'm looking for, are used extensively to connect fabricated sheet metal body parts on race cars.

So now I/we know where we can find rivets, have solved the problem and shared the information, life is good.

Regards,

Ron Fisher.
 
If you want a rivet which will be strong and corrosion resistant, consider Monel. Rapid Rivet has Monel rivets--although I am not certain that they have this specific rivet in stock.
 
What tool is required to set that rivet?

Ordinary rivet tools will set 1/8", 5/32", and 3/16" rivets, but not 1/4" or other special rivets, which require larger tools.

It takes a LOT of FORCE to set a 1/4" steel or Monel rivet! Hydraulic tools work great for this!

Auto body shops often use 1/4" rivets, perhaps you could borrow a tool from one of them, if that's what you need.

On Edit: Don't set a rivet in fiberglass in an undersized hole or fail to use a backing washer or plate. The force of the enlarging rivet shaft can crack the fiberglass if it creates too great an expanding stress of the fiberglass! Then you have a whole additional problem to solve!!! :smileo
