Hi,
From: Jeffrey Williams [EMAIL PROTECTED]
Subject: High temperature wire - also small LEDs
Someone on this forum had a source for small quantities of very small 
diameter high-temperature wire, suitable to wiring headlights and 
running through the smokebox.  Discussion was maybe 6-9 months ago.
I have some 0.05 (1.3mm) PTFE 7 core wire in Red or Grey.
You would be welcome to a length of each, please contact me directly if 
interested and I will post to you.

# Continuous Use Temperature: PTFE - 500 deg F, FEP - 399 deg F
# Melt Temperature: PTFE - Does not melt, softens at 625 deg F, FEP - 
500 deg F

Also, does anyone have a source for white LEDs smaller than the common 
3mm diameter?
White LEDs are available down to 0603 surface mount packages.
Digikey http://www.digikey.com/ have some smallish ones, see :
http://dkc3.digikey.com/PDF/T042/1338.pdf
... bottom of page. Or
http://dkc3.digikey.com/PDF/T042/1360.pdf
Note the LEDs are under L, not Optoelectronics.
You can also cut down the normal LED plastic packages as long as the 
metal bit inside with the bond wire is not disturbed. To finish off the 
light emitting end you can stick on a thin piece of transparent plastic 
with superglue and it will be clear again. (The superglue should be the 
non-vapor type.)

Best wishes,
Susan.

Anyone have this reference handy?

I don't remember that discussion but try magnet wire.  It's thin and is 
coated with a hard shellac.  Use the wire as one conductor and the frame 
as the other.  You can also pass the magnet wire down a hollow tube that 
might be used as a hand hold or dummy plumbing.

I have been using ordinary magnet wire on my C-16 and K-27. Have had no 
problems so far.
