Has anyone had any good or bad experiences using Fusor Metal Adhesives? I'm considering using it to bond my outer longs on and the long clamshells on. Then using structural rivets to prevent the unzippering effect of the bonded surfaces.
Pros I've read 1. Metal adhesives shear strength is greater than spot welds or the sheet metal being bonded. 2. Provides corrossion protection on surfaces being bonded (bonded surface) 3. No warping of metals, unlike welding. Cons I've read 1. Bonded surfaces can unzip, which is why a spot weld or rivets ar needed along bonded seam. 2. Don't let it get into areas that you don't want bonded or filled. Any thoughts are appreciated. |

Pretty piss poor metal properties for those rivets.
Prolly pop rivets so that the operator can easily exert enough force with a hand tool to pop them. For contrast, I'm now working on a product made from 17-7PH stainless with a yield strength of 220,000 psi. It's about as tough as it gets. A lot of the military structural fasteners are in the 130,000 shear range... Have you ever looked at an airplane? those are solid shank rivets with one formed head and one peened over head. Note they are on a 2 inch or so spacing to get enough cross sectional area to hold on a skin panel. The number of rivets and the patterns change to an even closer spacing for structural work. If yer rivets are hollow (pop rivet style), the hole really weakens them. For stress calculations, subtract the hole from the available shank to find out the area in shear..... |
