Still, in-person transactions aren't foolproof, at least when I'm the
fool. Went to a local Ace store and asked for a chuck key to fit a
3/8" Jacobs chuck with a 15/64ths (0.234") pilot. The pilot's right,
fits just fine. but the pinion gear is too big.
 
It's a nice bike ride to return it and I don't think they'll give me
much pushback if i want to exchange it for the right part, but that
was a one star deal too.
 
Thanks for writing!

Is the K number of the key stamped in tiny letters on the chuck?

It's marked SM4G61, with capacity in millimeters and inches. It
also has the spindle thread stamped on it. There's no K number
visible.

 
If you find one with the right gear but too small a pilot you could sleeve
it with hobby store brass tubing, stretched to almost fit and pressed on.

I don't think it'll be a problem to get the right key. I just wasn't
paying enough attention. In fact, "hobby store brass tubing" will be
considerably harder to find, at least around here.

It would have been smarter to take the chuck with me.
