Ryan,

Yes, it's a good design, and mine is actually very similar.
I bought mine from a friend, and it has about 300 turns of 12awg
wire.  There are about 6 taps for various inductances, or I can
pull out the core which was originally a mix of threaded rods and
steel welding rods.  The 6 tap wires go to a selector switch. 
I eventually replaced the core with the "I"s from old NSTs, which
increased the total inductance.  

Cheers,
John
