How to fasten galvanized pipes? Answered
Hi there, I have a lot of galvanized conduit of various diameters that I found in a dumpster. I would very much like to know how to fasten one pipe to another so I can make stuff with it.
Welding: I've read on instructables and elsewhere that you will become quite ill if you weld galvanized materials due to the evolved zinc fumes. Are respirators an option?
Lap Joints: I thought of trying to make a lap joint by cutting out matching "half rings" from the pipes, overlaying them, and then bolting them through. I'm stuck as to how to make that cut though. I could do it in wood, it seems like metal would be trickier. Any thoughts?
I'm being forced to move the pipe in a week or so; any off-the-cuff ideas would be fantastic, thanks!
