A Cool Method For Bending Tubing
« on: March 10, 2007, 05:50:36 PM »
I saw this on the Discovery Channel today. They were showing a guy building custom Trombones. When it came time to bend the thin wall brass tubing, he fills the tubes with water, plugs the ends and freezes them. When he bends the tubing filled with ice it doesn't crimp!

HOW COOL IS THAT !  (Pun intended) H^^

I wonder how he keeps the expanding ice from splitting the thin tube?

The caps were simple plastic caps that slipped over the ends. I imagine the caps are pushed out rather than the tubing splitting.

The brass should be tempered before bending.  Heat it red hot and quench it in water.  Then fill it with water and freeze it.  Should bend like spaghetti.

Copper tubing is much better to use for fuel lines in tanks though.  It doesn't corrode and split.
