Great job Forrest! 27 years ago i built a 22' tall x 24'' OD secondary Tesla Coil that had 1 1/4'' copper primary coil operating at 75 kw input! I got 34' long arcs to the ground with an 80' diameter safe zone around the coil! I had much fun but many in my neighborhood could not watch TV ha ha

Hi very impressive you put lost work making those coils. what is the voltage rating of those capacitors ??? how you discharge your capacitors ??? what is a safety spark gap ??? how you make one ??? once the vacuum sucks the Ozone what you do with it ??? some people complains about frying their cameras, phones and any other electronic devices how you protect your electronic devices ??? what size wire are you using ??? how you make a coil tuner ??? Thanks.

Hi - that's a nice looking build, you will need to avoid strikes to the woodwork unless you like the smell of charcoal! Output looks nice too. That static SG with a small cap (small for a pig that is) will never properly cope with the output from the pig so I look forward to seeing similar or even better results when you get that 15/120 NST replaced! I guess that most TC builders will do some of the four stages in the opposite direction to you, so did you learn anything special doing things your way around (electronics first)? Keep up the good work. Thumbs up.

would love to those beautiful coils in person do you go to any meets or show's. im buliding my first. and would love to get a parts list on your terry filter.

Have you ever tried a bifiller coil for the primary? I'm curious about how it would effect the circuit

Quench the spark, with magnets (and nitrogen gas also works)

Hey Bud. Very impressive, both from a performance as well as an aesthetic viewpoint. I do have one question. What type of ballasting did you employ for the input to your pole pig to replace your dead 15/120 cold cathode/NST?

Hi Dave, Been a while and hope you are well. Green monster still going? The pole pig I am using is current limited just like Ed Wingates......using the primaries of two small Lincoln arc welders in series while shorting out the secondaries. By switching to different current settings on the welders one can limit the current really quite well. My big RSGTC is run with this on 60 amp tap setting and I am using around 80 amp peak thru it. On my small SGTC I use the same welder setup on tap 20 amp and the TC works just fine. Hope this helps. I am planning on taking my big DRSSTC to roger smiths teslathon on aug.19 in Chillicothe ohio.Bud

Spark gap ozone? The 6 foot streamer makes a lot too right?

Hi, im building a tesla coil and need the spark gap to fire at 40khz to get the primary to resonate at natural frequency 24.6mhz. Is there a way i can measure the bps/frequency accurately without damage to the device?

You are asking for 40,000 brakes per second.....not possible! The primary collapsing field will ring and resonate with the secondary at 40khz. Even if we ring the primary once per second. What we try and do is ring the primary as quickly as possible. If you are using AC line current it will be 60hz. If you are using DC and a rotary spark gap then you can go as fast as you want within reason. The faster you ring it the longer the streamers will get.. Hope this helps

Are you still reading the comments mate - What could I build next - Bi-polar Tesla coil, 3 coil Tesla magnifier coil, Sync rotary spark gap coil, non sync rotary spark gap coil, super series non sync rotary spark gap, all of the above but use a high voltage DC driver, Different power supplies, NST`s, MOT`s, Pole pig, PT`s - and on and on - have fun.
