    Hi Nisa, This is how I bend tubing without denting it. First I plug
    one end of the tubing. Then I drop a string or thread into the tube
    depending on the size of the tube. Then I melt sodium thiosulfate
    (photo fix) crystals and pour it into the tube. Then pull the string
    out. This will remove trapped bubbles. After it re-solidifies, you
    can bend your tube with fingers or pliers. I place one end of the
    tube in a draw plate or bench block with a variety of holes drilled
    in it. Make sure you have a close fit. The tube will bind in the hole
    and allow for little tube waste. The chemical will make a cracking
    sound as you bend the tube but will support the tube from the inside.
    After you are done melt the sodium thiosulfate out of the tube by
    placing it in hot water and your done. I think I found this process
    in Oppi Untracht's Jewelery Concepts and Technology, but I can't say
    for sure. Have fun. 

Best regards, Kevin
