Default Best Machining Proceedure/Method???

Dear All:

I've got a part I need to machine (repeatedly) and was wondering if
anyone might make a suggestion for an effective and inexpensive
method. A photo of the cut that needs to be made can be found he

You can see the collar on the upper right part has been cut ~90°.
I've been thinking of using a 5C collect in one of those cheap spin
indexers you can get at ENCO for ~$30. The collar is less than .250"
thick by ~ 1" wide, material is silicon bronze. I'm a little
concerned about controlling the part as I spin it by hand since the
spin of the indexer is direct without gears and can (I think) move
freely front to back while spinning). A photo of the spin indexer can
be seen here;

The only other solution the I can think of, for a professional looking
finish at least, would be to use a $$$ super spacer or to buy a chuck
to mount on my rotary table with the 3MT center (which has it's own
problems of set up time and PITA factor).

Thanks,

John
