Cold rivet snap size help please
Hi, I'm a complete newbie here, a complete novice too.
I'd like to get into small scale model engineering...but as a hobby only.
This site looks fantastic, and there appears to be a wealth of knowlege here, and at some time in the future, I'd love to be able to contribute maybe.
Anyway, I'm wondering if there are any resident 'Yoda' types here that can help please? (Fingers crossed ):roll
I need to do some cold riveting.
The rivet size is fairly small, and the shank rivet diameter is 5.5mm, or 0.21" (or near, that's the closest I could get on my vernier)
What I really need to know is what size snap do I need to get a nice round head when it's beaten down please?
I've tried to work it out....and I'm thinking iro 1/8" to 3/32" ?
I've bought a 3/16" round head snap off ebay, but found it's a bit big...wayyy too wide and deep, so I'm a bit confused, what size to order next.
As there possibly will be many, many rivets involved, I'm hoping to use my trusty air chisel which takes .401 dia snaps to peen the rivets over.
Just wondering if anyone has an idea or if there's a standard size I should be going for please.
Appologies for dropping a question on you guys with my first post :)
Sorry, I've duplicated this post, I think I posted on the wrong part of the forum.
