Re: Pipe scraps




Robert,
Experienced indeed!  Such efficiency.  52" with 900 watts!  Way!
Awsome!  What are the specs on your micas (series, parallel, individual 
value?)
I heard that you use really big chokes on your neon to protect it.  How is 
it
holding up?  How long have you run it?  What brand of neon do you have.
Is it new or used.  Primary, flat spiral or dish or?

I used two 5kv photocopier transformers with a grounded center arrangement
which use about 2400 watts (using the 20 ampere breaker test).  I don't
know the number of turns but it has 5 lbs of #18 heavy formvar magnet
wire on it with .065uF polyproplene capacitor with a rotary gap.  I think
that the dent may be a detriment.
Barry

|Barry,
|
|Sounds excellent!..._but_ how much input power did you use?
|I have a single 15 kV -at- 60 mA neon
|powered coil, multi-section static gap,  0.008 mfd cap (made with a bank of 
30
|mica's), secondary 24" wound length of #26 on 4.25 inch dia, 3/16" thick
|'salvaged' PVC sewer pipe from a construction site.  I luckily found
|some lengths without bulldozer marks.  I did not prep the tube with
|any coatings before winding.  Several coats of varathane after,  I can get 
52
|inchers to a large flat surface grounded metal target.

|You're talking to an experienced scrounger here! : )
