How strong is JB Weld?

[kim_dude]

For my RRBO bike I need to mount a post to attach my jockey shifter to but all of my tubes have been modified, so there's no way to use a band clamp or something similar. I was thinking of JB Welding it but wasn't sure about the durability of it since I've never worked with it. Strong enough to hold up to being a shifter anchor point?

My Dad patched a crack in an aluminum oil pan on our ATV when I was a kid, it lasted for years.

A good trick is to use the 2 part jb weld and mix in metal shavings with it; it gives it a bit more strength. We did that to the old air compressor cylinder and it held for 5 years.

So you're saying its pretty strong.

Yea but adding metal shavings makes it stronger

Titanium putty is about the strongest but....
What you are trying to do is not really where glues shine!
You cannot add a tapped hole?
Or if welding, cannot add a mount?

Can't really weld since the body mods are mix of fiberglass, filler and aluminum.

You need a thread insert!
