Moosetrot Posted December 3, 2009 Posted December 3, 2009 I was once taught there is a formula or ratio for figuring out what length a rivet should be so it can be properly peined. That was about 25 years ago... Now I finally have a need to use that info and for the life of me can't remember what the formula or ratio was. Being at the age where I can hide my own Easter eggs, I would appreciate any help on this one. Thanks! Moosetrot Quote
bigfootnampa Posted December 3, 2009 Posted December 3, 2009 I don't know what you were taught but I like to have about 1 1/2 times the rivet diameter extending beyond my join for making the rivet head. Just a bit more for small rivets and maybe a little less for large ones. It depends a bit on what kind of heads you want but upsetting much more material than this becomes difficult... especially in smaller diameters. Quote
ThomasPowers Posted December 3, 2009 Posted December 3, 2009 What he said, 1.5 x Dia of rivet. Now you can fudge either way depending on how you plan to head the rivet, (flat, countersunk, connical, dome, etc) I picked up an old metalshop text bookfor a dollar once just for such info, handy to look things up in and easy to understand.
