You might want to try the method I used. I cut short pieces of 3/4"
dia. acyrlic tubing to use as hold downs, then bonded them into place
with Methylene Chloride adhesive. I fed the copper tubing through each
piece and then glued it into place on the plexiglas strips mounted on
the coil form. You can see how I did it on Chips webpage under new coil
pictures. The process was rather tedious but it worked out well, and is
very sturdy.
