So you did this in the water using a jack under the quadrant?

Does McMaster have these in the right size or was this just to show what
they are?

Hi Joe,

It needs replacing! I did mine a couple o' years ago. 

The source was my local bearing shop, a stainless steel beauty for less
than $40.
It's called a two piece clamp-on shaft collar (pay the extra for
stainless steel):

Measure carefully... it is not a common industrial shaft size. 

I used a small bottle jack (no real pressure)  under the hub of the
quadrant to support the rudder and hacksaw'd the collar off. I didn't
want a bunch of grinding dust to deal with. Use a high quality blade
<insert Starrett ad>. Surprising how well it went. There was a plastic
material bearing piece between the collar & shaft  log that I left in
place (eventually renewed after I dropped the rudder during a re-fit).

        Cheers, Russ
        35 mk-1

Underneath my quadrant is what seems to be a steel/iron collar about an
inch tall that has a few setscrews in it. This thing has been rusting
away now for decades and may need replacing soon.
1 - What is it?
2 - How does it come off? Can it be done in the water?
3 - Where do I get another one?
4 - Does it have to be metal? Maybe I can get one made of HDPE. I got my
upper rudder bearing made out of that last year and it works great.
