Don't have the thread about your rudder shaft.
Did see this company (Palm Beach) that says
"Seaworthy will restore corroded shafts on both rudders and propeller
shafts which are pitted and causing the seals to leak. Many times,
corroded and pitted shafts can be fixed and give years of good service
after our restoration."

Don't know what process they use, but might be worth calling.

Here's his response, and my followup - he's checking with local shops which
MIGHT have a big enough lathe...

Hi, Randy, and thanks for the response and call.

I measured; the largest dimension c/l is about 34".

I'll wait for your followup; thanks again.

Hi Skip,
I did see the pictures. Oxygen deprivation is the cause. Some of the
larger
prop shops can turn rudders depending on the center line to the fartherest
point of the rudder blade. They need a large bed on the lathe. If they
can't
swing it to weld and turn down, we use a product called Belzona which is a
very hard type epoxy which can be machined. The trick is the area for
repair
needs to be sand blasted so the epoxy will stick to the metal. Then we
heat
the area to draw out any salt residue and clean using acetone and apply
Belzona trying to sand it in place before it hardens up. by the way, we
are
located at Seminole Yacht Center just north of the PGA bridge in Palm
Beach
Gardens.
Regards,
Randy Downs

Ah, well...

The largest prop shop in the WPB-MIA area has only an 18" lathe, and mine
is 34" o/c.

Back to plan A, and to Harbor Freight to pick up a cheapie sandblaster for
final cleanup...

Thanks for trying.

I was thinking there might be enough demand to do this type work
on-site. There's quite a bit of portable machining being done.
Probably mostly high-cost for bigger stuff though.
Though I'm not a machinist, it seems a portable grinder on rotating
collars isn't a difficult machine to design.
Pits would be welded up, then the grinder clamped on either side of
the work area and rotated to bring the welding down to the OD.
Anyway, you should do well with your approach.
Mind your packing selection, cutting and stuffing.
I did plenty of packing work in the Navy, but it was all pump/turbine
shafts, and valves, and no pitted shafts or valve stems.
So I can only suggest one more thing.
Good luck!

There is a method - "Stationary Journal Machining"

Looks like it can be done-

Thanks, Wally,

Update...

I'm in the middle of searching and contacting, but mobile machining appears
to be fairly common for some industries.

I'm hopeful of finding one nearby so I can drive it there, or not have weeks
and hundreds of bux tied up on shipping.

The main problem I think I'll find is that this is a tiny job compared to
what the companies who do this sort of thing normally tackle, and not worth
their messing with...

Thanks for thinking outside my box, which I didn't do very well!
