Hello group,

I needed to ask you how to hold down the turns of copper tubing.  I've made
8 supports with slots cut and drilled into them, then I lay down the tubing
into the slots and volla, one primary.  But it doesn't lay flat enough and
it wouldn't take much to jar it out.

Any input would be appreciated,
Thanks,

Shaun Epp
