Re: [APD] What do you make siphons out of?

["S. Hieber" <shieber at yahoo_com>]

You can sometimes buy rigid tubing from lfss and on-line
fss. While most carry the small diameter for use with
airlie tubing, some carry the larger diameters. The trick
then is to heat and bend it without causing a crimp. The
easiest way if you have the parts is to insert a close coil
spring that's jsut a little smaller than the inside
diameter of the tubing. Heat the tubing and bend around a
post carefully, hold in position until it cools. You have
to be carefull to not get the tubing too hot -- jsut enoung
so that it can be bent without stress fractures. The spring
should keep the tubing from crimping. 

The spring needs to be one that bends easily. Hardest part
of this is finding the spring.
