How do you replace Bigsby arm?

[Mojoe01]

I have a Bigsby B700, and got a Chet Atkins arm for it. The only problem: I have no idea how to take the original arm off. Has anybody done this? I can find plenty of resources that tell me the arm can go on any Bigsby, but I can't find anything that actually says how you take them off. Thanks guys!

Remove the strings,lay the arm back,remove the spring,undo the nut and remove the arm.
Re-assembly is the reverse.
