Shaun,

One way which works well for me is to drill holes somewhat bigger than your
tubing in your supports.  Then saw through the tops of the holes along the
length of the support.  You will end up with partial holes which look like
Cs with the open side up.  The trick is to cut through the holes so that the
copper tubing requires some pressure to snap into each hole.  Supports made
out of white plastic breadboard or other non-brittle material have enough
"give" to them that they won't break when you force the tubing into the
holes.  The tubing will stay put with no additional restraining methods
required, and it looks good.
