| rivetgun Hello, I am wondering if it is a good idea to build an aluminium boat and fasten it with pop rivets (sorry I could not find a proper translation, but I mean the rivets you shoot in with a rivet gun. I ask this because on the one hand I like luminium as a building material, but I don't have any welding skils at all. Thanks  |

| Many, I would even say most (and all before the invention of TIG/GTAW welding), lightweight aluminium boats are built with rivets and "rivet guns" (i.e. pneumatic hammers), but they use solid body driven rivets, not blind "pop" rivets. The reason is obvious if you think about it for a moment.

| Sealing pop rivets are fairly common. You will want to over seal them anyway regardless of type. Here they are on McMaster Carr: http://www.mcmaster.com/#pop-rivets/=huj8vo |

| Maybe you could try the aircraft method of using soft aluminum rivets and a pneumatic riveter. You drill the hole, temporary hold the parts down with clecos (you need a cleco plier), drill the second hole, remove cleco, insert the rivet, place a backing plate and start riveting. An so on and so forth. Downside, you may need an assistant to hold a backing plate in deep areas. Tools and materials available from aircraft suppliers. |

| I think that you are right, because an aspect that I have overlooked, is that the "pop rivets" have to be the same marine grade aluminium. I just keep toying around in my head, (I am building a 25ft wooden boat right now so that will keep me busy for a while  Another of my brain f***ts, is to build sort of lapstrake and use epoxy also, for bonding, the rivets would than serve as permanent clamps.  It would be great to be able to pre bend the alu strakes to get an efficient use of the material, and the lapstrake hull would be quite strong. I keep looking and toying with this idea. Cheers |
