would like to see a pic of bullet shaped bungs

I bought a few of these when I started on my project, but so far I really can't see where they'd be useful, due to not having enough contact area with whatever tubing you'd weld them to.
But maybe I just don't "get it".
(lol, wouldn't be the first time)

Would love to see some pics of bullet shaped bungs in use on your bikes, if anyone has such a thing.

thanks!

Like these?




Use them for fender struts mounts..





.. pics from lowbrow

thanks! hadn't seen those particular pics on Lowbrow - but I do love their tech tips section. I guess the other (low) end of those struts have a different kind of bung on the end - that's great, because I'd wondered what that type would be used for, too. (the kind where the fastener sinks down flush into the bung)

ok cool! let me ask you this - did you dish out the frame tube any, to accept a round bung to round frame tube interface? I had wondered about that before. Or can you just weld round to round?

thx!

Technically you can weld virtually anything together anyway you want. In the example above with what appears to be a license plate frame it probably doesnt matter either way since its just gotta hold a plate and a light. For strength the best way would be to cope one or the other slightly to accept the bung and weld it with little to no gap and more tube to tube surface area to lay weld on. Or better yet drill through the tubing slide the bung inside and weld both edges of the bung.. which would be the strongest. Also doing it this way the shape wouldnt matter as much if you were running a closed bung rather than a "through" bung you can just fill weld around the arc'd end of the bung to flush it with the tubing. (similar to a plug weld)

.. another lowbrow example (in these pictures their bungs were only being used to fasten a tank to the back bone therefore drilling through the backside of the frame and welding the backside of the bung wasnt necessary. For anything structural though i wouldnt hesitate to weld up both ends for rigidity in the bung and added frame strength.. takes a couple more minutes but why skip steps if it keeps your shit from turning to swiss cheese)

those are called counterbore bungs.

heres another variation on the bullet bung:
