Bummer. Looks like you need to find someone to make a collet or a new drive washer for it, as well as the prop washer too. There ought to be some machinists or hobbyists with the tools around that can make those parts for you there someplace. Unfortuantely I can't have you come on over on a weekend, so I can check it out and maybe make something, as we have too much distance between us.
