I also have one of these, Code 100 and the converter to do Code 83 rail.
I have hand laid several hundred feet of Code 100 NS on Clover House wood ties, and I found it a big improvement over driving individual spikes.
I recommend it highly to any one considering hand laid trrack work.
I have a Kadee twin rail spiker for both code 100 and 70 rail along with 6 boxes of spikes (6x 4,000 each) i am no longer interested in keeping. If anyone is interested, PM me off line for more details.
Have Fun.... Bob.
