How to thread an aluminium rod
I have got some 1 inch aluminium pipes (GI pipes) which I want to thread. I got the threading machine (hand held racheting type) and when I try to thread using that, it goes about 2 threads and after that, its pain - so stiff and even after exerting all my force, the pipe wont thread.
I had read that to thread easier, you should coat the pipe with Wax or threading oil. Is there any other tips or tricks that you have used for threading? Any input is greatly appreciated.
