Have any of you welding/fabrication types ever tried making a ring.
Seems like slicing off a proper sized piece of pipe and polishing it up real nice would work.
Have you ever taken a beer bottle and just lightly clinked the mouth of it repeatedly against the mouth of another bottle? If you do it just right, it'll snap off cleanly right below the base where the cap goes on. I did this once and then using some wet sandpaper, smoothed the rough edges and made a ring out of it. A girl I knew wore it for quite a while until she dropped it when she was playing around with it and it became little ring shards...
Of course, everyone on here would never do that because they'd rather fill the bottle...
