Hi from Vancouver

[Scott__M]

Hi,

I'm new to the forum and am hoping someone might be able to lend a hand...

I have a couple of ooold Crouse Hinds explosion proof lights that I am trying to refurbish...problem is they are seized up pretty tight.

I have tried all the "basics" on getting them apart...I have:

-applied penetrating oil (not WD-40)
-tapped with a hammer
-used a torch to heat up the outer parts
-waved a dead chicken over a picture of Bea Arthur

I'm now looking for tips on freeing up stuck cast aluminum. I have done a lot of reading and it seems that two pieces of aluminum will essentially bond together due to the formation of aluminum oxide...

I have read that ammonia can dissolve aluminum oxide so my next attempt will be to soak the parts in ammonia and hope for the best.

If anyone has any other ideas...I'm open to hearing them.

Thanks in advance for anything you can send my way.

Scott

Welcome to the GJ. Ask that again in General Discussion.

Welcome from downunder Scott, cast aluminium can be tough to deal with, I have not had a lot of experience with it but I am sure there will be some here that can help.
