Anyone ever attempted to repair broken aluminum? What were YOUR results?
I'm attempting to repair an aluminum carb body. The broken part is one of the posts that the float pivot pin goes thru. This particular one is off a generator. So far, I've (twice) attempted this repair and met with dismal failure. Product I've used is JB Weld steel, which is "supposed" to be good for aluminum as well. I've never attempted this type of repair myself, but have read numerous accounts of other people having great success at it.
I've mixed, in equal portions, according to the directions. Cleaned with acetone, again, according to JB Weld's web site and no joy in both cases. Epoxy stays tacky, and repair fails.
One possible problem.. is epoxy too old? Maybe. Not sure when I purchased it, but it doesn't appear to show any signs of degradation. Resin is black, hardener is cream. and when mixed they turn grey, which is what is supposed to happen.
Any thoughts? Any suggestions on different products? Replacement carb is around $130 so it's advantageous to repair if possible. Doubly so as it belongs to forum member Barb (OutoftheWoodwork) and I don't want to annoy her.
