Bucking Rivets (Bucking Bar Guide from 3D printer)

[ryane67]

This is really an excellent idea. First thing printed for the -14 project, I'm sure this will inspire many more uses for my CR10s

Oh my... I could have used that this evening. I would pay for one of those.

I'll take one of the buck bar guide tools.

FYI - the design shown here is for a 1" x 5/8" bar, I've made a revised design that will accommodate the 1" x 1" mini tungsten bar from cleaveland but is the same in every way. Happy to send the STL files along as well.

For a few moments I was thinking "maybe I should buy the 1x5/8 bar" but I decided to be cheap and change the tool-helper instead of buy another tool for once

I reckon this is awesome. Forget international shipping - one email with a file that was - 19KB - (less than 20,000 characters) emailed on Friday. By Sunday arvo I’ve got the part in my hand. Could have done it even quicker but *life*.

Simply AWESOME!

Thank you Marc.

Hi Ryan,
I’m building an RV14a and this holder would be great. I have a granddaughter in high school learning to use one of the 3D printers and realize she could build one of these holders for me. I sent you my email address in a PM. Could you send me a Copy of the latest version of the STL file?
Thanks,
Ted Mifflin

Ryan,

I'm in major need of this. Will you please send the files? I've sent a PM with an e-mail address.

Thanks, and FABULOUS idea!
Mike

I got a 3D printer for Christmas, so figured I may as well start with something easy. Doesn't get any easier than a square! I made 3 different bucking bar "guides" for my tungsten bar - one for 3- rivets where the shop head is on a flat surfaces (no dimple), one for 3- rivets with a dimple in ribs (so same idea as the OP with a ledge to account for the rib flange height), and one for 4- rivets on a flat surface, like the spar. The reason they are different sizes is because the ledge that the bucking bar bottoms out against is made to have the thickness of a properly set rivet in those different scenarios. Overkill for sure, but fun to play with.

This was more about the learning experience than anything, but pretty awesome to be able to draw it up and have something in hand in such a short time!

I used mine this weekend on my rudder! Thanks, Marc! It worked great, though I saw a few areas for potential improvement, so I did. First, the hex on it was bigger than any sockets I currently had, so I made the hex fit my largest socket (a 22mm socket). Next, when I was playing with my print I realized, I could have just put a 3/8 drive hole in it, so I did that too. Now I can turn it with a socket, a 3/8 drive racket, a box end wrench, or an adjustable wrench. Whatever I feel like using at the time. The STL can be downloaded at the link below for anyone who wants it.

That's a great idea, Brandon! Would you be willing to share the file?
