Homemade Spring Offset kit

Has anyone ever made there own or seen it done before? I want to do a offset shackle and hanger to gain 3/4 or 1 inch or so of tire room but really dont wanna pay 200 bucks or more for the kits. The shackle itself seem easy just bend them in a precise location the same amount on both sides. The hanger I'm not sure about?
I dont want to do the relocation. I dont want to cut on my frame nor do I need that wide of a tire. I just a little over a half an inch. Thanks for any help.
