Mike, the aluminum was purchased at Alreco Aluminum Surplus, Henderson, CO 80640.
Hope that helps you. Photos coming soon. |

Trying to get these photos to show with clicking on them..:confused:
I was presented with a sheet of 5052 in the .080. A bit stiff but we will get it done.;) First we made the basic pan with a depth if 1.5 inches. I was very careful setting the box break as to not get too tight on the bend and we also drilled the corners before bending. Attachment 47925 |
5052 should be a good choice. From your pics I think 80 thou should be ok. It's used in marine applications because of it's corrosion resistance. It typically comes with some temper but it's easy to anneal by heating to 650F. I usually anneal with torch, the heat is uneven so I get a little ripple in the sheet but if you are forming it the ripples won't matter. On extreme shapes I will anneal more than once. The work hardening will add to the yield strength so I usually try to do some shaping after the last annealing to increase the yield strength.
Definitely get 5356 filler. It yields a strong, ductile weld that will hold up to subsequent shaping and planishing. Commonly available 4043 makes brittle welds with 5052 and in my experience makes a slightly visible weld line after polishing. |

After making the pan we went about creating the other pieces. The bottle holding brackets. Then the mounting tabs.
I thought cutting those slots might be a bit easier in the mill.:D Attachment 47945 Attachment 47946 Attachment 47947 Attachment 47948 Attachment 47949 Attachment 47950 |

We might as well finish this post. Sorry for the delay but I became a new grandfather since my last post.
I need to mention that the Aluminum that was purchased was 5052 in 080. Plenty stiff for this project so no beads or flairs were needed.. After all of the pieces were fabricated it was then check for lay out. Cutouts for fan locations and clearance. Then installed Nutserts and welded the project to life!:rolleyes: Then added a makers mark.:D All went as planed and my friend was very pleased.
