I was starting to wind my primary (3/16" copper tubing with 3/16" between
turns). I made 4 plexi supports and drilled 3/16" holes to wind the
primary in. I mounted them with silicone onto my TC table I made.
I waited over a day for the silicone to dry. I had my girlfriend come
over to help, we got almost half way and all the silicone supports ripped
off, GRR!!! It was getting very hard to rotate through as well.
I don't know what to do now.
I know a lot of you say to drill the holes half way into the supports so
the tubing will "snap" in but it is too late for that. I have a chop saw
but it has a standard DeWalt blade (for wood) in it. Even if I went slow
I would be scared that it would crack, chip, or shatter. Any suggestions
Silicone glue is not a glue at all. Just a sealant. Use proper acrylic
glue, or better, screws (some may argue that metal screws are now
something that you want close to the primary coil, but there is no
There is no technical reason to use copper tubing for a primary coil
of a low-power Tesla coil. Any wire stiff enough to keep the shape will
work, with losses that you will see only with instruments.
Apply some oil to the blade when cutting acrylic, and it will cut like
