I've used an 8' long pipe, put the nut onto the axel when you bend it so you don't bugger up the threads. To get more toe out is easier then toe in, cause you can tie onto the tail wheel area and use a cable come along to pull on the end of the pipe. It does take quite a bit of power to bend the gear. Most will say that 0 to 1/8" toe out is best. JImChuk
