I've used their N scale code 55 #6 - works like a charm! Best operating switches on the layout.
I recently purchased their N Scale code 55 crossover. I haven't had a chance to make one yet, but I'm dying to give it a try. For the price, this is the jig to purchase. You can make a regular turnout (left or right), a single crossover (left or right) or a double crossover all from the same jig.
