Red-hot with just a 15/120 NST?  With my 15/60 NST and 5/32" tungsten
rod, I can touch any part of the propeller-gap electrodes immediately
following a 1-3 minute run.  The stationary electrodes do tend to get
hotter due to less airflow, but definitely not approaching
incandescence.  

I don't mean to nit-pick, but 1/4" rod is a bit pricey and unnecessary,
IMO.
