Playing with Holes, Translucency and Internal Lighting

Am interested in getting past just Reflected Light bouncing off the
OUTSIDE of a turning by looking into adding a light source to the INSIDE
of a piece.

Been  playing with little battery powered LEDs inside turned pieces -
using holes to let light out - and translucent material (white PVC pipe)
to allow light through.  Have found a variety of small, inexpensive,
battery powered LEDs and have done two Proof Of Concept pieces that
demonstrate TRANSMITTED LIGHT and TRANSLUCENCY Lighting.

So far, so good - and - as the guy on Laugh In would say - "Verrrry
Interrrrestinggggg.".

Your chuck is taking up too much room, IMO..
My guess is you're losing about 1 1/2 or 2" in the difference between the chuck
and a small drive spur or such..

OTOH, it this helps, I used to turn 18" hair pins on my mini, by running the
stock through the spindle and through the chuck (talon), and extending the end
to the tail stock..
Turn 2/3  of the piece and reverse..
I found that if I put a layer of blue masking tape over the sections that were
in the chucks "inner jaws", the didn't get marred at all..  YMWV

You need something like a dentist's drill that could make small holes
from the inside, and not go all the way through.  Then the spots would
just glow.

I think glowing magic wands would be a big hit with the kids.  They'll
need to be voice activated with the right spells though of course ;)

Drilling partial holes from the inside to produce glowing spots - great
idea.  Have a foredom handpiece that's about the diameter of a Sharpi
pen and some ball end bone burs.  Will have to try that.

Have a TeknaTools live center with a 3/8" diameter through hole.  Hadn't
thought of extending a turning through it.  But, assuming I'm not
starting with 3/8" diameter blanks, I'd still have to hold a blank in
order to turn the tail stock end down to 3/8" or less.  Guess I could
start with a larger square blank extended through the back of the chuck
and pick up an additional 1" or so of length capacity.  But beyond that
I don't see how to to use the hole through the tail stock end live
center.  Care to explain>

charlie - maybe I missed something - but in answer to your question - when
I'm turning a lamp and I want to drill the hole through the center for the
power cord, I run the drill through the center of my live center

I was asking for clarification of a method "mac" wrote about

"OTOH, it this helps, I used to turn 18" hair pins on my mini, by
running the
