[Heathkit] Nichrome wire

[Robert & Linda McGraw (K4TAX)]

There is a very good article at www.somis.org/Oct88qst.html.  As a source 
for Nichrome wire, a heating element from an electric clothes dryers is a 
good one.  Check with your local appliance service organizations.  An 
"independent" servicer might just have an old junker that you could extract 
a element for little to nothing.  Also might look at "2nd hand" stores for 
some type of eclectic heater that could be had for a few $$ just to obtain 
the heating element.

Based on anode currents in modern legal limit amps, you'll want heating 
element material that is typical of 120 volt or 230 volt elements in the 
1500 to 4500 watt range.  The wattage rating of these appliances have 
nothing to do with the "power rating" but just the fact the wire size is 
larger.  As to the "ohms per given length" topic, I haven't seen any issues 
raised here.  The turns vs. length vs. diameter relating to inductance of 
the coil is the key factor.

Rich Measures, G3SEK or GM3SEK has some very good information on the topic. 
Check out his websites.
