I am using some aluminum 2024T6 and 6061 left over from a homebuilt full scale build. I used JB Weld to "glue" the parts together. I have read a lot about using this high temp epoxy and glowing results. We shall see. Other, and I am sure better option is to weld. Without the equipment and skill this would be expensive though. I have not tried the high temperature aluminum solder. Might be an option.
