Wow! You've done everything I would have tried but one. Try beer. 

Buy a 30 pack of Coors Light and have it iced down, in a cooler, at your boat, 
and let it be known to the yard mechanics that that is the reward for getting 
your rudder free. I expect at least one mechanic will be over after work and 
others may join to help him get it done for you. If you can get the guys 
interested, the worst that will happen is you will make a lot of friends with 
the yard mechanics. But I think someone will accept the challenge and step up 
and prove himself.

Subject: Stus-List Rudder collar "donut" removal 

I have my boat hauled out now and am trying to drop the rudder. 

The stainless steel donut that holds the rudder up, above the thrust bearing in 
the cockpit, is very much stuck. I removed the two set screws and am attempting 
to unscrew (counterclockwise), with the rudder propped up (enough that that 
delrin bearing under the donut is free spinning). 

This is the donut pictured on Wally's page:

He got it off with just an oil filter wrench + exhaust hose on past occasions, 
and later with that strap wrench. I've already applied far more force than a 
strap wrench with no luck. :( 

I had planned to have the yard (Seaview) help with this, but apparently they 
have plenty of fiberglass guys but not enough mechanical guys, and are 
backlogged on anything mechanical. So if I want this to go faster I can keep 
trying to do it myself. And saving money by not having them bang away at it for 
$105/hour is probably good anyway. Though honestly I would happily do that now 
if they could get it loose. 

I know Frank of S/V Cool Change had a bear of a time with the set screws: 
http://cnc-list.com/pipermail/cnc-list_cnc-list.com/2007-March/009523.html (but 
I guess the donut wasn't a problem?) 

And I know another owner who used a huge pipe wrench with some padding, and 
yard assistance, but ended up damaging it and needing to get a new one. 

Things I've tried: 
- PB Blaster, every day for 4-5 days, around the top, into the set screw holes, 
and around the bottom. 
- Loctite Freeze + Release 
- oil filter wrench with rubber pieces to grip 
- threading a bolt into the set screw holes and hammering on that - quickly 
abandoned this because it started to bend the screws and I realized it would 
strip the set screw holes. 
- C clamps 
- Heat gun (I don't have a torch - however I don't think heat will be very 
successful because the mated parts are both stainless steel) 
- Large hose clamp tightened around my rubber gripper ring and hammering on the 
hose clamp screw. I really thought this was the genius idea that would finally 
work. Nothing budged, even with heavy pounding. But the hose clamp does the 
best job of pressing my rubber gripper onto the donut and had no slippage. 

Is there anything I'm missing? Has anyone else had this hard a time getting the 
donut off, or found anything else that worked? 

The Edson radial drive bolts are also seized, but I have some more things to 
try there still, and as last resort it can be cut off and order a new one 
($500). 

If I can get the rudder out I might also consider changing the stuffing box, 
because that is also seized (looks original and probably hasn't been adjusted 
in 5 years).
