[PSUBS-MAILIST] glueing aluminum

[hank pronk via Personal_Submersibles]

 Alan,I will research it and I like to test also.  I actually just overhauled my LED light bar for Gamma and removed the original rubber seals and wire penetrator.  I put it back together with a urethane windshield adhesive, that stuff is amazing and cheap.  the light bar had an annoying little vegetable oil drip that landed on the dome and then while towing the drips would go down the side of the sub.  Glue has come a long way.Hank

 Hank,they glue steel laminations together in electric motor stacks so I don't see why aluminium shouldn't glue together successfully.   Depending of course how you are gluing it. If you are laminatingsheets together they should be pretty strong.When I was searching for a pvc glue for sealing my penetrator wiresI tested a number of glues people suggested, but the glue that was used commercially on pvc boats won hands down. Worth researchingwell.Alan

 Alec,My research so far shows that aerospace parts are glued also.  I am sure the Lotus folks are pretty closed lipped about how they do it.  I will do some testing, just checking with the group to save some time and headache.What are you using for a ballast an now?  or is it a surprise.Hank

 Lotus Cars famously have done that, introducing bonded aluminum chassis with the Elise and continuing it on subsequent models. The reason is that welding weakens the material, so if it were welded they would need to increase the amount of material and it would eat up the weight savings. Problem is, I don't know the specifics of the glue they use nor the process. 
Best,Alec

Hi All,I have an idea that requires glueing aluminum plates together.  Has anyone tried this?  any success?Hank
