Highpower,
Are you referring to the ratchet itself, or the arm that acts as both a collar and to hold the handle? I'm a bit confused because of your references to "diameter" and "casting".
If its the arm I'd go with a weldament out of 1018 cold rolled or hot rolled. Machine as necessary.
If its the ratchet it would depend on what if any heat treating equipment is available. I'd probably go with 1018 also, but case harden the teeth and keep the core relatively soft to reduce the chance of breaking the teeth.
