I need to attach this bracket to a petrol tank.
Tank has been through the acid tank at the engine reconditioned, I've also washed it out with soapy water and rinsed it thoroughly. I then soaked some paper in wd40, set light to it, and dropped it in the filler hole from a distance. Didn't go bang.
I've been grinding on it for about an hour and nothing bad happened.
I'll probably not air it for a while and try to light it again before I commit though.
But, the main question here, is can I tack this with mig and then braze it?
Would mean I can tack it on the frame to get position just right, then position it nicely to braze.
What about the flux though? Will it flow under the bracket? Should I drill a 15mm hole in the tab so I can flow braze from the middle?
Bonus question.
I then have this small hole to deal with. I was going to braze this as it will be neater, and less likely to chase it. I've been tapping and wire wheeling the area and can't find any other holes about to appear.
My only concern with brazing it is the amount of time I'll be putting a flame on it. Potentially releasing trapped fumes. A mig tack would be over as soon as it's begun.
