hey guys me and my pa are having some issues with our boat having a leak. we narrowed the problem down to two things one of which is the rivets being loose. my dad knows of a tool that tightens rivets but doesn't know of its proper name. i was wondering if someone could point me in the right direction?
his description was:
it is a power tool that has a cupped end that uses a hammering action to tighten it while on the other side of the boat metal frame a person holds a solid peace of metal so that it is compacted and forced to tighten.
it would greatly help if someone knew the name of the tool. we plan on tackling our project boat this weekend and where hoping to solve the problem but this is currently a road block. *grins*:whistle:

This can also be done with a couple sledge hammers, I would be worried about them leaking again regardless of the tool, if the boat is used hard.

Harbor Freight has an air hammer with all the rivet bits for about a hundred bucks but a lot of times this is temporary fix as the metal in the rivets have worked quite a bit and may need to be replaced not just retightened.

The tool is a rivit gun not the air hammer that is sold for automobile work. The air hammer hits 3000 times per minute and the rivit gun hits a lot slower and it is controllable My Ingosal Rand AVC 13 can give a single hit to seat the rivit then a few more to wake it up and then opened up it for two seconds or so to drive it. It requires a rivit set (metal punch sized to fit the button head of the rivit), and a bucking bar (auto body dolly would work in a pinch)
You would need to clean the seams really good and force marine sealant (RTV 5200) in between the two layers of metal. As long as the hole that the rivits are in are not hogged out you could use a hammer and dolly to restrike the rivits. Just be sure that you and your dad are on the same rivit. The results of you missing would be a ding or worse a hole. The dolly needs to be held tight to the bucktail (round flat section of rivit usualy inside the boat) and hit the head of the rivit to compress the rivit some more to tighten and swell it to fill the hole. :twocents:
Good luck.

Y Gunner,
I have done this with 2 alum boats in the past. Cheaper to use 2 hammers. heavier one as base, lighter one to tap the rivet.
When I did it, I stood the boats up on the stern (used a rope and pulley) then I could control it easy. No leaks when done.
Good luck with it and take your time.

well we got a little shock when i took the boards off. the guy before us had use packing peanuts and styrafoam(the kind that acts like a sponge) for floatation foam... no wonder the thing had to run the bilge the whole time.

Installed new rivets in my Starcraft 2 years ago. Son was inside with the backup hammer and I ran the rivet gun. Hope you have a good pair of ear muffs.
