I don't see where to request to admins to lock a thread. can somebody request. If I get anymore moron posts directed at me they will get trolled severely. I don't think thats a productive way to run a forum.

Maybe admins should give people a chance go delete any idiot posts they are embarrassed by in hindsight. My posts stand.

The issue I see is that the tension on the headset cup is gone. I also would doubt the strength of fibreglass vs CF.

I have been making a bunch of CF addons and some directly on the powder coated tour bike frame. I did not scrape anything to bare metal. It holds just fine. The seat tube is entirely wrapped. I first tested how to apply the resin and wrapped a busted fork with 3 layers I guess. After 2 days setting I tested it by whacking it as hard as I could with a hammer several times. It barely showed a dent in the not fully hardened resin.

I later tried a temp fix on another broken fork, that uses a drum brake arm and broke 90% across there. I wrapped it in 2 layers and rode it a few days later, 123 miles actually. The next day the CF ripped at the fracture. So apparently that is not a good use for CF. The replacement tandem fork was wrapped 3" where the clamp goes. Zero chance it will break there again.

We wouldn't be having this discussion if the crack was in the blade of the fork.

1. You can request to have your thread locked (or moved) or report any posts that you feel violate the Guidelines/Rules/Principals by clicking on the black triangle with the exclamation mark inside (far left of the "reply with quote" and other buttons).

2. A person can modify or delete their own post(s) by using the "edit post" button (found next to the "reply/reply with quote" buttons.

Please note that if you do decide to use the "Report" function, that it is for either an Administrative task that isn't granted to the thread OP or to report clear violations- and not simply to report someone due to a differing opinion than your own (applies to everyone).

Awww. Don't tell those companies that pay a lot of money for the design of composite frames for satellites. They seem to work pretty well though. (Also, please don't tell the PTO.)

I think you are successful at shifting the discussion away from the engineering principles that govern composite design. Early in the thread someone generously mentioned why successful designs minimize the matrix:filler ratio. That's a clue. As built, your patch can't relieve the stresses causing the cracks, so they will continue to failure.

Keep shaking your fists at the universe; maybe you'll eventually win. =)

...oh yeah, I forgot. I don't know if it still works this way, but it used to be that if the OP (you in this case) deleted his original first post, the thread would automagically disappear. Now back to the Tour of California. #heretohelp

that will also work for anyone who feels posting threats about 'severe trolling' (whatever that is) might be a violation of the Terms of Service...

just sayin'...

We may not agree with the method he chooses to cover up his flaws no matter how cracked up they may be but we will defend to the death his right to ignore our brilliance.
