RF,
YEs, there is another way of doing it without a Dremel, but it is basically the old file and sandpaper thing. A dremel makes it much easier.

As for the tail wheel, I wouldn't recommend a hard install into the rudder. Unless you tailwheel hinge and rudder hing are perfectly aligned, this could cause binding. A simple method of attaching it, while allowing it to move slightly is to put a piece of fuel tubing over the tiller and then strapping it to the rudder with a piece of thin sheet metal (like a piece of a Coke can).
