RE: [TCML] Newbie - input regulator

["andrew" <andrew@xxxxxxxxxxxxxxxxxxxxx>]

Thanks Jim. 
Ah! That makes sense.
I'will stick to my crude rotary to start with and see how it goes.
Been looking for 2nd hand variacs on trade-me. (our equivalent of
e-bay)without success but I like the idea of the garden wire reactor. Anyone
got a drawing or picture?

In My Feeble Memory,

Richard Quick used to put a RQ gap in series with the RSG to reduce the Gap
energy on the rotary. 

Long Sparks,
Jim Mora

Hey Richard, drop us a greeting!

Thanks Jim
I did not recieve your reply to me in the daily list email but found it in
the website list anyway.
I shall do more research on sources for mmc capaitors.
 
With regard to controlling input current,
you said   
" One of the more unique ideas was using 2 or 3 inch 50.8,76.2mm , plastic
pipe coating the inside with oil for a release agent and stuffing it full of
Florist wire which is already painted green generally (The pipe should be
long enough to have a couple of inches to spare).

The coating and small diameters dramatically reduce Eddie currents, losses,
and heat. Put some kind of puller in the wire, cap one end of the pipe-
stuff it with the wire, stand it on the capped end and fill it with epoxy.
Wrap the pipe with #6 awg or #4 AWG insulated wire and voila'. Some one else
may be able to give you an idea of the number of turns for 4KVA-5KVA control
( I am assuming 240V, are you 50 or 60Hz?)."
 
That sounds like something I could make. Does anyone know the turns etc I
could use or is it just "suck it and see?" Yes we use 240v 50 Hz in New
Zealand, and it is spring here!
 
My other question was,   "2. Some people use a rotary gap and static gap in
series. Why?"
 
 
Cheers
