Re: Is riveting that much better?
just a heads up on the klekos:
they can be purchased from an aircraft supply store, if you want i could post the link (i would have to look it up quickly) Basically, to drill all the holes we use templates. we drill one hole, put the drill template on top (the templates are just like ruler with holes drilled various distances from each other, commonly use 3/4-1 inch spacing) we kleko it in (kleko=temporary rivet) and then we drill the opposite side hole in the template, kleko that in, and then drill in between. short quick description: a kleko is a temporary rivet that is inserted with a plier like specialty tool. it holds things together so that you can align before you actually put rivets in. (you want to space klekos approximately 3-4 holes apart on straight lines, or about every other hole on complex parts like the curve in the picture mentioned) 50 klekos will do most teams well, i believe we have about 200 or so ![]() |

Re: Is riveting that much better?
If you use nuts and bolts, use nuts with a nylon insert so they lock in place.
Also, last fall we used some machine screws that had a nylon segment incorporated into the threads, which made them locking, but not permanent. |

Quote:
Very large rivets (think George Washington Bridge) are heated so they flatten more easily, with the important added benefit of shrinking when the cool, thus pulling the joint together even tighter. Small rivets (think FRC177 robot) rarely are heated. |

Re: Is riveting that much better?
Looks like Cleko and Cleco are the most common spelling
