    ๐Ÿ“ Sail Servo, power switch type
    26 days ago by Joe727 ( Midshipman)
    Flag
    View All
    The location of the sail servo was determined by mocking up all sail sheeting and through deck opening locations. Servo is a Futaba S3802, I have used this Servo type on many boats including my US1Meter racing yacht and some sailing fishing trawlers. Very powerful.

    The servo arm is scratch built out of carbon fiber sheet and I use fishing pole eyelets in the openings for smooth sliding of the sheets.

    While wood glue is drying on the servo mount blocks, I am prepping the power switch. See photo for Dubro switch type that I use on all of my boats. You must buy a small slide switch to mount on this. I modify these by threading a longer metal rod to replace the short one in the kit. This enables me to mount these through the boats deck and keep it above the deck somewhat to keep water sloshing on the deck from getting in the boat.

    Examples of the end result are shown in two photos, one from my brooklyn tug and one from my rescue pusher tug.
    More to come.

    ๐Ÿ“ Wheelhouse, Masts, Booms, fittings
    1 month ago by Joe727 ( Midshipman)
    Flag
    View All
    The Wheelhouse was designed to cover the rudder servo. Just mocked up right now, built with basswood, more detail will be added. Hole in roof is for the Mizzen Sail sheeting. Made two sheeting tubes out of brass which I am about to locate and epoxy through the decking.

    Masts are made from birch and are hand tapered with a small wood plane. All booms are made from discarded carbon fiber arrow shafts. I have been using these for years on all of my boats including my 1 meter racing yachts. Fittings are made from bits of wood and brass. I use hand tools to cut and form the brass and wood items.

    I spent two years on a work assignment on Grand Cayman Island and I built a Falmouth Gaff rigged cutter to occupy my spare time. All I had was some hand tools I brought with me, I learned to stay away from power tools and got back to the way I learned from my father and grandfather in the 50's. Now, I first try to build most things with hand tools only, it's very satisfying. More to come, thanks for the interest.

    Joe, I don't know if, or how much you have studied the type of barge that you are building, but there is an excellent book on the subject, 'The Big Barges' by Harvey Benham and Roger Finch. The one you are building 'Pearl' of Ipswich is mentioned and photographed in the book as she was the last of the Ipswich boomies and ended her days as the 'Pearl Wood' at Hoo after spending some years as a powder hulk anchored off Gravesend.

    Cheers, Nerys

    Nerys,
    The two books that I used for my research are Sailing Barges by Frank Carr and Barges by John Leather. Both have photos and drawings of the Pearl and the history as you mentioned. I chose the Pearl because there were enough drawings that I could build her from scratch. As mentioned earlier, I am building a RC boat so primarily the hull and sail types will be close to the original. The deck layout will be more to accommodate the RC aspects of the boat.

    As to the sails, I will use the general sail plan however, I first determine the Center of Lateral Resistance of the hull during water float tests, then I design the sails to the correct Center of Effort. Then I cross my finger and hope for the best during sea trials.

    Working on the sail servo, arm design and sheeting now, more photos to come once I get through this effort.

    ๐Ÿ“ Deck & Hatches
    1 month ago by Joe727 ( Midshipman)
    Flag
    View All
    Sub-Deck installed and I will have to decide on planking later. Hatches framed out, hatch covers made from basswood side and very thin plywood roofs. Used neo magnets to secure covers in place, these are very strong magnet!

    Slot through hull, barely visible, is for the keel. Modifying an old US1Meter keel and lead bulb as needed for sailing at the pond.
    Bowsprit bits shown and opening through bow for sprit which will be retractable for transport and storage.

    Working on masts and booms to accommodate gaff rigging, etc. Wheelhouse and rudder being designed now.

    My focus is on making a RC Sailing boat, so I am not replicating fine details of the original barge, but making everything workable. My background previously has been on racing boats, like the US1Meter class. More to come shortly, working on this full time (retired), started again last night. Thank you for your support.

    Your progress is very impressive, I can see you having her sailing in a week or two from what you say. Lovely shape bow on her. You seem to be doing everything right at very high speed and I think your decision to make her principally a sailing model rather than to precise detail is a good one.

    Pleased to hear that you have resumed work on your ketch rigged barge.You were getting on so well with her when we last saw photos of the framework. Really looking forward to seeing the completed model as these 'big' barges are somewhat overlooked by most model barge builders.

    All the best, Nerys

    Hi Joe, My planning wasn't too good either. I used balsa strip to make it easier, filled in with filled and lined the interior with fine glass matt and resin. As I often become became in the lake I sail on in S.France I installed an on-board motor. I used part of a fiberglass fishing pole for the last and did away with the rigging to save time at the lake. It sails very well. Ra

    ๐Ÿ“ Auxiliary motor, rudder servo, bowsprit bitts
    1 year ago by Joe727 ( Midshipman)
    Flag
    View All
    Back to posting again....I decided to added an auxiliary motor since I had several laying around and it will come in handy when I am tweaking the sailing setup in case I get stuck in the middle of the pond. Made a stuffing tube just like I did on my rescue tug build. Made a shaft from some 3/16" steel rod, threaded it and polished it up, works great.

    Photo of the aft section shows continued hull framing and upside down mount of the rudder servo. I will enclose the servo with the small pilot house as is typical on the barge. This will make maintenance and adjustment access easy.

    Yes, the build is wandering away from the true "Pearl" which I used the hull plans from. it will maintain the same sail plan, but I will modify some items for ease of RC use.

    Bowsprit will be retractable, bitts are shown in progress. The bowsprit will be made from a carbon fiber "arrow shaft". Mast will be wood and I am shaping out of maple that I have.

    Staring to plank the hull as well. More to come shortly,
    Joe

    ๐Ÿ“ Rudder location, blocking, fabrication
    1 year ago by Joe727 ( Midshipman)
    Flag
    View All
    Looking at the proper rudder location, I added some 1/4 triangular hardwood blocking to both sides of the centerboard. Needed blocking to drill through. Was able to pickup the work board and all fit under my drill press to keep the hole plumb. Rudder post will be a 1/4 brass rod with brass tube as a bushing. See photo, brass tube in hull.

    Next, I built a rudder substructure assembly which will be covered later with a wood or styrene full size rudder to fit the era. Took some very thin brass and formed it around the post, some brass plate and soldered as seen in photos. Brass heats up and solders well using my soldering station.

    ๐Ÿ“ Simple Building board
    1 year ago by Joe727 ( Midshipman)
    Flag
    View All
    Hello, Photos attached show my quick inexpensive building board. All I needed was a lightweight, movable board that I could clamp to.
    I had a scrap of tempered hardboard about 35" x 16, so I cut two strips from it at about 2" wide from it and used them as legs to keep the thin top flat and straight. Then took some scrap wood pieces as a method to glue and secure. Result was a little table that I could clamp to. Hope this makes sense, but point is work with what you have, I considered a trip to the lumber company for wood, glad I didn't.

Photos show my makeshift board with clamps everywhere. Joe

    Steve,
    You are quite right, I intend to flip it over, build some jigs, when it's time to do the hull "planking". My methods are to experiment along the way on a Build, try different ideas along the way. Decided that I first wanted to build a very straight, rigid keel with stern and bow ribs first. That's why the build board is just a lightweight flat straight surface, I figure out how to clamp it best as I go. Your interest and comments are appreciated, it made me think more about the planking, thanks! Joe
