Re: [TCML] Tesla Coil Magnet Wire

I use a laminates and plastics 10" blade on my table saw for cutting HDPE, would work for any cutting board. I found a one inch thick board of HDPE Plastic I drilled the holes to fit 1/4" copper tubing then cut through them with table saw to make them insulated supports for the primary coil.  Got it from sears, sure you can find same blades at home depot, lowes, harbor freight, etc.  It will have smaller teeth than a regular wood blade.  I have used the Temco brand magnet wire from Amazon/Ebay on both my secondarys.  The original was 26awg on 4" pvc.  The latest being 20awg on a 6" secondary form of pvc.  

I used the same caps in my MMC .15UF 2000VDC.  but I used 16 In a string.  Started with 1 string.  Now I have 4 strings for a total of 64 caps.  Started with 12kv 30ma.  Then 12kv 30ma x 2.  Ended up with 12kv 60ma x 3 for 10ma total.with 64 caps.

Subject: [TCML] Tesla Coil Magnet Wire 

Hi all, I'm gathering supplies for my new small Tesla coil (4" x 20"
winding) and have a few quick questions.

I calculated to use 26AWG wire for this secondary, I've heard it is best to
use 22AWG or larger but I believe that is only for larger coils correct?

I found some affordable wire on Amazon:


This is 26AWG Polyurethane with a Polyamide over-coat. Does anyone have
experience with this manufacturer (TEMCo) or have suggestions on a more
reliable source? I'm willing to pay more for better quality but within
reason of course this is just a small coil.

I'm planning on using 13X0.15uf/2000V capacitors for about 10pf at 26KV
driven by a 12KV/30ma NST. Do you think that is sufficient voltage on the
MMC? I'll be using an adjustable PowerStat 20A power transformer so I can
run at lower voltages at first.

I can add more capacitors (30 total) but then the capacitance drops too low
towards resonance and I don't want to destroy my NST =)

I am still in pre-build stage so any suggestions would be very welcome.

Oh also does anyone know the best way to cut cutting board for supports? I
figured a table saw is inappropriate I do have a small band-saw but I guess
I'd need a different blade for plastics vs wood?

I'm trying to source some thin-walled 4" PVC but no luck so far except
special order for 20' lengths at menards - that won't fit in my car =)

Thanks for any suggestions!
