Steering Bracket questioon

Hi all
The attached image is of the bracket at the top of the rudder in the lazarette. Obvioulsy needs some attention - either replace or clean and paint. Have cleaned and applied some rust kill as a temp measure.
Would this be a part I could purchase or better/easier to get one fabricated?
Also I see how tto remove it but want to ensure I dont drop the rudder out the bottom!! It looks like the rudder is held in by the bracket around it just underneath this bracket.
Is this a job I should attempt in water or wait until it is hauled out for antifoul?

You might try some POR-15 to paint it first. They make a line of products to clean and treat the metal then paint it.

Comodave - yes i brushed and sanded it back to a reasonable finish and applied some Rist Guard Rust Convertor, will take down the top coat next time. But still feel it should be replaced if it is critical

From the photo I thought it was just surface rust, does it go deeper? If it is just surface rust I donít see a problem with just refinishing it. However if the rust is deeper then I would replace it. If you are going to replace it then I would probably do it on the hard.

Yeah some of the rust was quite deep at a couple of mm.

Simon,

To answer your question, the rudder post is held vertically ie what stops it dropping down by the circular "donut" under the top of the bracket. The top horizontal arm is for the steering.

Looking at the bracket, it looks to be a rectangular box section - the bottom long side is what the "donut rotates on, the top long side - not sure.

Sooo, undo the donut and down drops the rudder so its an out of water clean up and repair/replace

I think the bracket would come off without touching the donut. Bit would have to remove the steering gear clamp above so I think decision made it is an out if water repair.
Now just need to find one.

What is the bracket doing? I had a bracket like that, but there was no completed box section at the bottom with the donut. There were 4 bolts securing each of 4 "feet" to a wooden base. As far as I could see it did nothing and had no function,not being attached to anything. Yours may be different.
I had mine looked at by 2 people, one an ex Halvorsen shipwright who thought it was for a type of steering my boat did not have(? hydraulic, mine was chain/cable).
My fittings were badly rusted, I cut the fittings(one around each rudder stock) so I could remove it from around the stocks without disturbing anything and undid the 4 bolts. The boat continued to steer and operate normally for the next 2+ years with the brackets removed.
Just have a good look and make sure the bracket is actually doing something.

I think the rusted bracket was where the original bearing was. Or maybe it had 2 bearings in the past. The bearing is what keeps the rudder shaft from dropping and 2 would be insurance.

BruceK and Lepke - as far as I can tell nothing. Hadnt thought that it might be superflious. It is bolted to a wooden frame below and as far as I can tell nothing else

No idea what the bracket is for. Early Willards used a different type of hydraulic steering ram (Wagner T-Ram) that encircled the shaft vs attach to a rudder arm. But shaft was keyed, not squared; and probably just a north American thing since the steering systems were PNW based (the larger T-Ram systems are still built). My best guess is this bracket was some sort of spacer.

To answer the original OP question, brackets like these were fabricated one-off pieces even when the boat was originally built. There would be no source for a replacement even if this boat were 6-months old. Getting replacement parts from builders is usually extremely difficult and expensive even for current model boats. Bears no resemblance to dealer networks in automotive industry.

Clean it and paint it.


Nobody going to say anything about the empty bonding connection?

I actually noted the bonding connection. Didn't say much as it wasn't part of the exam question.

Im redoing my bonding system as we speak. Had teeny solid core wires - probably #12 or so. Going with #8 tinned/stranded.

Do you mean the earth strap, as far as I remember it is in good shape, have you spotted a problem?

It appears in the photo that there is a missing bonding wire on the left side in the photo.

I have been redoing my bonding system. I did the port side last winter when I had that engine out. This winter is the starboard side since the starboard engine is coming out this winter. It is amazing how many connections there are in the system.

See what you mean but I believe it is a black wire bent back, but will definitley recheck. Thanks for the headsup

It is identical to my IG. The top is welded to 2 pieces of angle iron if I remember correctly. Any machine shop could fabricate the piece. Quadrant would obviously have to come off for replacement. Upper bearing would not be touched. Mine are lightly rusted. I took a wire brush to them once but haven't touched them otherwise. Lazarette is my damp dungeon where anything that doesn't have a reserved place gets tossed and forgotten.

(IG's used flat cu strip for bonding, not wires.)

That square piece of metal bolted to wood by 4 bolts and surrounding the shaft, looks like what my IG36 had around each shaft. What is it doing? One theory was a retainer preventing excess movement in the event of rudder strike. I can`t see if there is something functional relating to the shaft located underneath the metal plate, so it might be doing something.
