    Default Need help finding a skeg-mount gudgeon

    Hi,

    I am building a 13' Sharpie and am trying to source the rudder hardware. The upper gudgeon/pintle are conventional transom-mount and I have that hardware in hand, 5/16" pin. Stainless.

    Because the transom is so narrow, however, the designer has specified that the lower gudgeon should mount on the skeg, which on this boat is 1/2" thick. I have searched and called several suppliers and can't find such a part.

    Any ideas? I could try to bend the sides of a conventional gudgeon, but I don't think it will want to fold up neatly and if it does, may be metal-fatigued when done. Same with heating and bending. I'm not sure I would trust the part to be 100% strong afterwards.

    I could have a part made, of course, but that seems like an expensive option. Any help would be much appreciated.

    thanks,

    John

    I've used a pair of the vertical gudgeons on a double-ender, which is what you're probably looking to use when mounting rudder hardware on a skeg. You could probably order one horizontal (transom) and one vertical (skeg).

    I bought them here:

    Nice stuff. I bought a pair of the vertical gudgeons unbored and drilled them out myself.

    I took the advice here years ago and bought a pintle that fit the skeg, did a sex-change operation (silicon bronze is easy to cut and drill) and it came out very well. The hardware from Duck Trap is wonderful but sometimes need a bit o' fettling.

    Look at Duckworks
    This vertical gudgeon worked for me, and they are heavy duty. Nice.

    With a table saw, drill press,grinder and file you can machine some Al bronze (Aluminum or free machining brass is easier) bar stock you can knock out a set in a few hours. Drill, cut, then grind.

    These are Al 2519-T87. Pins are decapitated SS 3/8-16 bolts. Not for salt water but no corrosion after 8 years in fresh.

    It is very easy -- just get a silicon bronze strap pintle that has plenty of metal around the base of the pintle, cut pintle off and drill a hole through the rest of the base.


    Or buy one from Duck Trap and drill the hole, as I did with this piece on the skeg of my Cosine Wherry.

    Thanks for all the great ideas. I think I may have found a solution. I bought a stainless door hinge and with a little tweaking and one weld I think it will make a good gudgeon.

    Those are good fittings, I've used them on a double ender with a narrow stern stem, drilled the bolt holes about double the bolt diameter and depth about 8 x the bolt diameter and filled the hole with thickened epoxy, covered the end with masking tape, put the bolts, studs really, through the fittings to provide the correct location then pushed the bolts in through a slit in the tape. Note, I used very long bolts to get the length of thread I wanted, cut the unthreaded part off and set it up so I had the nuts on the outside . Boats three years old now, has had more than its share of abuse, and there are no signs of anything coming loose.

    Optimist stainless rudder pintles fit 15mm stock for under 10. You could do something with the pin if you wanted a gudgeon.

    Must sell 'em in the USA.
