That is way too much trouble and is not required.  I think whoever said "no
metal screws" was probably referring to the secondary and even then it's OK
if you take precautions.  I use steel bolts and screws all over the place
with no problems at all (and I'm getting 6 ft arcs out of my NST coil).

If you have metal sticking through your secondary then you need baffles
inside the tube.  If you use them on the primary supports like 99% of
everyone else, then you just take reasonable measures (decent spacing) to
make sure the arc is happier going through the primary than through your
bolt/screw.

odd topic, hmm?

here we go..

I read and have held firm to the "do not use metal screws in tesla coil
construction".  If any of you have built boats or have looked into that,
you know what this is about.  For those of ya'll who dont, a treenail is
the 1600-1700's answer to the nail.  Its basically a piece of dowel with
slits  sawn into the wood about a 1/2 inch long, both ends.  you would then
drill a hole in which ever pieces of wood you were going to join, and then
place wedges into both of the slots.  with the wedges still in, you would
lower the dowel into the hole and hit it into place with a mallet..
When the wedges were hit, the ends of the dowel would expand, acting like
the treads of a screw...

Get any of that??

good.

So, could they be used to hold together the base/table for the primary??

Why not screws, btw, and what are YOU useing??

second section..

has anyone ever known/heard of NST's retaining charge after their unplugged?

Thanks
Erik
