Thanks for the replies. This is what I ended up doing...
I drilled out the holes one size bigger (since I didn't have any other
plexi bits I used a standard with oil like was suggested when cutting with
a saw, worked great, no chips or cracks). I then used clear epoxy (no
carbon) and they seem very strong. I will try winding soon again and see
The copper is still pretty soft so I am not too worried about that (yet).

Copper tubing, when suplied in coils is softened. After being bent a few
times it becomes harder and very dificult to work with. My guess is that
when to were making the coil you had to make severall adjustements to it,
and it hardened the copper. Even your suplier might have hardened it if he
unbented it to measure and then bent it back for you to take home.
To soften copper tubing you heat it with a flame, BE VERY CAREFULL, COPPER
BURNS INFECT VERY EASILY AND THERE'S ALSO THE FIRE RISK.
When the flame becomes green, you cool it with water or a very wet cloth,
be very carefull again!!.
Why dont you try to make the coil on a form a then aply it to your board?
