[QUOTE="tensixniner, post: 628816, member: 699"] Damn, this thread turned hilarious fast. I'll do my best to answer the post made in response to my previous one. I'd use chemicals to degrease as much as possible. You can play with the AC balance however you like, it's only going to help remove the aluminum oxide on the surface and won't do anything beneficial in removing the greasy dirt. A file, sandpaper, burr ... etc can also be used to help remove the oxide layer minimizing the use of AC balance. Brass isn't used to braze aluminum, it just doesn't stick very well. There are other filler metals that can be used which are more appropriate. For example, 4047 can be used as a brazing filler. As far as a filler metal for welding it, there are also many choices. I'm sure one could be found which is suitable for this application. With a suitable filler and welding procedure the weld and the untouched casting would have similar strength charactericts, assuming the part wasn't originaly heat treated. A big part of doing this repair with welding or brazing is the skill/experience of the weldor performing the work. Also, the equipment and supplies they have available. In summary ... The method of repair is the customers discretion. My personal preference would be TIG over MIG but I am also not against trying a quality epoxy first. JB Weld probably wouldn't be my first choice.
