    Some things is best hid, but the real reason I'm adding a layer of veneer is to make up the thickness of the two pieces. Grown knees are a fine thing if you have a couple of suitable candidates, but you usually need quite a pile available to choose from. Laminating up a piece allows the same species to be used as the toe rails.

    The final decision about the location of the chocks and cleats can be put off for quite some time yet, which is not to say we won't be seeing them placed in various locations just as soon as the current work allows. The sheet horse is constantly in the way but I keep moving it back onto the marks because I like how it looks.

    The knees are still in a rough condition and I expect to be slimming them down as soon as the joints are fitted. I might be reducing the inside radius if I think they look to heavy once fitted. The outside edge needs to be planed to follow the curve of the toe rail smoothly.

    Thanks, Gary, you know I just love this kinda stuff.


    Here's another view of much the same thing. As can be seen there's a piece of wood clamped on to serve as a stop during fitting. The sock is filled with white parting dust that I usually use for metal casting, but is being used here like a chalk bag. You dust the deck, rub the piece in place and the dust shows up the high spots underneath. There's at least a half inch overhanging the transom that needs trimming once I work up the courage and can't think of any possible situation where I wisht I hadn't.

    That's the transom toe rail poking into the scene with the approximate correct overlap on the knee. The next step will be to cut the scarf on the end of the arm of the knee.

    The sheet horse needs shifting back onto its circle.

    Here's the inboard end of the quarter knee, scarfed to receive the ends of the transom toe rail.

    It’s daylight savings time here tomorrow so we need to set our clocks. It was nice of Jim to build a reminder into his rail.

    That's not a phillips bit in the drill, it's a countersink. The screws are driven by hand.

    The brass was screwed down without the holes having been countersunk. I didn't want to weaken the strips by countersinking and risk having one bend during handling. The plan was to install the strips into 5200 and then withdraw the screws one at a time once the goop had set up, countersink, and replace the screws. The heads get filed to the contour of the half-oval rub strip for a smooth finish.

    Jeez, I figured you were tough, but you drive screws with your hands?

    That rub rail looks snazz-eee.

    Jake, it's a damn shame, and all we can do is muddle along as best we can, and if we have to make it ourselves well we're just gonna you and me.

    Cold winter, Paul, nahhh, this is Long Island. Couple of days colder'n the rest but I remember worse. The greenhouse is like a sauna bath after lunch most days, sometimes hafta take off the hat.

    Fitting a scarf. The piece on the right is the toe rail crossing the transom. The scarf on the end has been cut to its final dimension. The piece on the left is the portside quarter knee. It's end has been roughly cut to size so the two ends can be superimposed, then scribed, and trimmed to fit.

    There's going to be four quarter inch machine bolts in each foot of the traveler, going through the deck and blocking beneath. I'm comfortable with it.




    Here's a little more on the toerail, if you haven't had enough already. The joints are fitted and the parts shaved down closer to the final size. The next thing to do is to drill the holes for the screws.

    There's one of those cleats I made, put there just to see how it looks.

    The cleat looks NICE, Yo. Really. I know we're on to other things, but it looks "right".

    I'd keep the cleats far enough aft, so if the main sheet drops on the deck in some off wind maneuver it won't foul on the cleat coming about.

    Thanks all for the kind comments. Navy, I would like to place the cleats far enough aft that a line can be sprung across the transom clear of the cockpit coaming. As you correctly point out sheet fouling becomes a problem, especially during a jibe. I'm kicking around an idea for a pair of slippers of some sort that can be put over the cleat to prevent fouling. It's probably too much trouble to be of practical use but a cleat could be made non-fouling with a couple of shaped pieces of wood held together with a rubber strip. The actual installation of the device could be designed to be accomplished quite easily.


    Here's the first time the clamps have been removed and an unobstructed view obtained. Until now it has been impossible to fair the tops of the pieces into each other. The inner and outer edges may now be taken down to their final dimension. The fun part, it's called.

    Herreshoff used pad eyes on the stern of boats to eliminate the problem of snagging the sheet.

    You mean padeyes instead of a horse...of course?

    Padeyes would not prevent the problem. When the main is out running downwind if there is a lull in the wind the sheets go slack and can drop onto the deck. Light winds and a chop will create the same problem. The boom can be rigged with a vang and it eliminates the issue. Well of the boom rizing and falling and moving all about anyway. If all that line is out when the boat is tacked it's likely to catch on something.

    Too bad they don't make bronze pull-up cleats. Non-traditional, to be sure. But would solve your problem.

    Looking on as ever, with interest.

    Can I recommend a light line lashing rather than rubber strip, passed through holes in the wood sabots passing between the two legs of the cleat? You can snug them up as tight as you like.

    No, pad eyes instead of cleats. In the catboat, with long boom and short broad stern, you have to watch the corners of the transom too.

    I can see why a pad eye won't snag so easily, but a pain in the but for securing a mooring line. Unless you tap the hole and screw in a cross bar when you need to moor.

    That's a good suggestion, Nick, a few quick turns and there you go.

    Thanks for the suggestion, Thad, I'll have to give it some thought. I do have this pair on hand which might be suitable. They will require sufficient commitment to drill two large holes in the deck, after which going back will take some doing. While they would be far superior in the fouling department I think they might leave something to be desired when acting as cleats. They'd be usable, but inconvenient.

    You'll have a cleat nearby for the sheet. One could argue that the padeyes are just the device to lead the mooring line to that cleat.

    If you are considering portable screw in eyes, why not portable screw in cleats?
    Something after this but with a screw thread instead of the flange.

    Should not take you long to turn out a pattern for casting.
