JB Weld, anyone?(10 posts)

JB Weld, anyone?seyboro

I am trying to glue the head badge back onto a Ti frame and have tried just about every adhesive on earth. What are the 'side effects', if any, of JB Weld or other kinds of glue originally intended for somewhat more agicultural applications?

Make sure that both surfaces are clean and add some small pencil marks on the center line if the parts. Put a small amount of JB on the badge back, so that it does not flow out too much, align the marks that you added and wrap the combined parts with an old inner tube under tension. This should insure a good bond and the tube will release from any excess JB. After the cure, use a hobby knife to cut away any excess JB. Should outlast you.

Thanks. Are you aware of any corrosion on titanium this stuff could cause? I'd hate to end up with a crumbling piece of head tube or a hole for a badge...

Ti is mostly inert with everything. That is why you do not need to paint it.
Try Tubasti. Seriously. (nm)Alexx

I wouldnt use JB weld, my guess is that its too harsh of chemicals for the carbon fiber plus once its on it will never come off. I would use the tubasti like was mentioned, or you could probably go to an auto parts store and get some 3M fastak. It was originally designed for automobile trim. Some bike shops stock 3M fastak for tubular tires.
Also, how about some GOOD,thin, doublesided tape?

I agree with the poster about the doublesided tape. I've used it to remount the chainstay protector on one of my oclv's and its held up well, and that's a nasty environment!

JB Weld is a very strong epoxy adhesive. It will work just fine to attach that head badge. Just don't expect to ever remove it.

Speaking of JB Weld and bicycles, a number of framebuilders use it to attach carbon seat stays to the frame. My understanding is that it works just fine for all the various frame materials, including titanium.

No worry.
