Re: Pipe Bending ?
Yeah sand is ok. Try to get the sand as fine as possible. Sand with clay in it seems to pack a little better. You can use a kitchen sifter to sift the sand or screen.
Also if you anneal (heat dull red hot and let cool) the copper first it makes it easier to bend.
Another method is to fill the copper pipe with molten solder and then let is cool hard then bend. Then heat back up and the solder will flow out. Not recommended for water cooler though as solder will remain on the walls of the pipe.
