    My stainless tube and aluminum ears had corrosion-welded. Tried for two days to separate them, no dice.

    I cut the ears off, then made a King Starboard overlay which bolted onto the remaining YS metal.

    Well, I finally got back to the boat to see what is what and I found out something interesting! The four screws turned out to be two perpendicular adjustment rods for the compass compensation. Thankfully, I figured this out before drilling them out! I had noticed that there is a sprung "pin" on the binnacle and had not figured out what it was - until.... I decided to just see if I could lift out the compass unit and noticed the pin move. I pulled the pin and the compass unit came right out, revealing the two compensation rods and four bolts that secure the binnacle to the pedestal. From there it was plain sailing. One mystery remains: I would expect the compensation rods to have a moving magnet or two associated with them that would adjust the field, but I could not spot anything. Has anyone seen a set up like this before and can you tell me how this works, or what my set up is missing??

    Thank you!

    Danforth Constellation Compass

    I have the same compass and case. Its a Danforth Constellation Express compass. Your little trick about pulling that spring-held pin in the case was just what I needed to remove the compass from the binnacle. Mine had a 2" bubble in the dome. I've talked to 2 compass shops--the going price to rebuild one is $250-$280. I refilled the dome myself with the appropriate fluid, but both shops said the leak is likely to re-occur. For $250, I thought home-repair was worth a try.

    They explained to me how the compensation rods work. At each end of each rod, there is a small magnet mounted perpendicularly through the rod (the magnets are "inside" the brass end-plates, visible in your photo). The "neutral" position of the magnet is parallel to the horizon. The compensation bars are only meant to be turned up to 90 degrees forward or back. As the magnet is rotated towards vertical, it has a larger effect on the compass. Obviously, one rod is used for N-S corrections, and the other for E-W.

    Both shops said this is a top-notch compass, and that a similar replacement would run about $600.

    I think I'll re-fit mine with an LED lamp when I reassemble it.

    Thumbs up

    A bit more compass trivia in a blog entry:

    My 2014 experience in a narrow channel handling big rough seas, proved that the card is more readable and comprehendable than the slower-changing heading info on the GPS screen, and mentally it seems to have a faster "acquisition time" for the human eye/brain interface.
    Of course, that might be due to me having a lot to think about at the time... and having an "interface" that has slowed with age...


    Thanks also for the information about the adjustment rods; I kind of wondered just how they work.

    A bubble in the fluid is caused by a leaky diaphragm. It's quite easy to replace the diaphragm and refill with fluid .
