Doug, I have not tried that particular brazing job, but I think it would be much better than just about any other method so far mentioned. However, that rotor housing is a large mass of aluminum to get up to temperature brazing temperature, so it would probably take a high BTU torch and perhaps a larger propane tank (like for the BBQ grill) rather than the smaller bottles. I would certainly try it on a junk housing first. But, seeing what they did in the H2000 video with that stuff, I would say it's certainly worth a try.

Hi Ed;

One old trick is to pre-heat and weld/braze with oxy-acetylene right on the BBQ. Don't let your wife catch you...and serve someone else the first burger :)
