Thread: The making of a Provent bracket.

The epoxy, JB Weld is good up to 287 degrees C. Nylocks are good up to 250 degrees C. I've got nylocks to fasten the Provent to the bracket.

How hot would the engine bay get near the fire wall, exhaust side?

Hence the original suggestion for rivets. There was an article on here many years ago on the incredible strengths of appropriate rivets, especially on sheer, and perfect as a backup for this type of application. Smaller hole than bolts/nylocks, less visually obtrusive, and not as affected by heat. Cheers

Almost done, just the paint and pop rivets, as added security.

Look great.

Would you believe it. The one and only join that did not have the pop rivet broke!
I'm glad I listened to those who said bolts and or pop rivets!

Thanks

At least you learn from your mistakes, probably the epoxy held initially until oxidation got to the metal surface and it let go. Too bad you didn't work at a TAFE, you could have got one of the students to weld it up for you as assingment.

The expoxy would stop ant oxygen getting to the steel. This was the next day I noticed the failur. Not long enough. Apparently J B Weld is good for filling in holes, but with any vibration it falls apart. A bloke I work with is a former mechaniccal engineer who worked at Tickfords. He offered to weld it, I thought the epoxy would work. Maybe there is a steel epoxy that works.

I'm keen try this Loctite product

I have a couple of welders, both arc and a mig, but sometimes they're inconvenient for some jobs.

A quick Youtube video comparing some epoxy products.
2x Loctites, JB Weld, Gorilla, Devcon FasMetal

The Loctite Metal Concrete wins the test, I thin JB Weld second last. List of results at about the 5:40 mark in the vid.
