    Paint is ok but I do like a bit of varnish for contrast. In fact, I get a chance do a bit of daydreaming and planning of other projects during varnishing breaks. Varnish, to me, is only a hassle if it is let go too long. I use the best brushes I can afford, good varnish and attitude for the job before it gets too long in the tooth!

    A varnished deck house on the H28 makes a good looking contrast to a well painted hull. My own choice and favorite wood for trim is Honduras Mahogany, Bright Star is African which takes a bit more of a fuss to stain it. but it is durable and gives good service. Plus, it looks great when varnished. We varnish Bright Star once a year which takes roughly a week for two of us to accomplish. Masts are done every two years and take about four days to sand and lay on two coats from a boatswain's chair. Since I grew out of my job, I let my wife Anne enjoy the view from the custom chair I built for her. wear sunglasses in order to see the contrast of the holiday skips and thin spots. Jay

    She looks lovely Jay. Well kept varnish does. On other peoples boats

    Greg, it would be worth giving Rogue Empire a call, in Huonville. They are mostly a furniture and antiques store, but have a back room stacked with slabs of tassie timber. And I think I saw a sign in there saying delivery $60, any amount to anywhere in Australia. Big slabs of Huon which would do a cabin side in one go were about $400. I didn't check the price of celery top, but probably cheaper and a great timber, stable, hard and pretty. As I say worth a phone call.

    Thanks for the comments all, plenty to think about. However I will definitely be giving her a bright finish, that’s been the plan since the very first day I took her on and with Bright Star as the bench mark I know I’ll have my work cut out to come even close to her finish.

    Thanks for the heads up re Rogue Empire Phil, I’ll definitely give them a call and I’ll also price up the celery top for comparison. I had been considering it but a few bits that I looked at on line seemed to be similar in price to the Huon pine. That freight cost, if they’re fair dinkum, sounds worth taking them up on.

    Greg my experience from the architectural side is that strong sunlight will degrade the timber colour radically, and no UV inhibitors or anything similar will prevent this, though they might slow it down a bit. I'm completely with you on the varnish, and, as long as the hull is white, I also like the lighter coloured timber for cabin sides. However, if the hull is darker, I think the lighter timbers for cabin sides look s**t (less than attractive). So I think cabin sides choice of timber needs to be done side by side with topsides colours. And lastly, in our climate, I think you need a cover over all brightwork, even the small stuff. But you're probably on top of all this already.

    Yes John, topsides will be an antique white, which I think I’ve now got reasonably formulated from the Thames skiff build. And agreed re the covers over brightwork, I’ve been keeping a bit of a quiet eye out for an industrial sewing machine so that I can make covers up myself, eventually.

    For Mahogany the trick of not having the color bleach out is to first use filler stain. I mix Interlux red and brown mahogany half and half to get the color of freshly varnished unstained Mahogony before the sun bleaches it. A coat of clear acrylic lacquer sealer goes on first to prevent the stain from muddying the grain pattern. Once it drys, often ten minutes on a hot day, the stain, which has been thinned to the consistency of buttermilk, is applied and wiped off with terry cloth or burlap just as it hazes off. Let it dry overnight and apply the first coat of varnish thinned out with turpentine to get penetration. A full strength hot coat can be put on as soon as it is tacky. If time permits, lay on a third coat when that tacks.
    Double coating can be done up until the sixth coat. I sand beween the next two. Hot coating gives fast build up. Eight coats is the magic number. More than that and you risk turning the job "Varnish Sick" which can result in blisters that result from heat soak and an overly thick skin. Filler stain is made of earth pigments and will not bleach in the sun.

    I've just bought one of these for just that job Greg. A friend has one and says it's capable of sewing 5 layers of canvas.

    I paid $100 for mine so I'd just keep an eye out for one at a price you like. Courier probably although Oz Post would do it. I'll go weigh mine now .

    Interesting: I’ve compared a few prices and, if I’m doing my calculations correctly, I’m seeing plane Huon pine planks (i.e. not advertised as highly figured or anything special) for sale at roughly $12,000.00 m3 from one seller, $15,500.00 from another and even $24,444 from one .

    But Celery top is showing around $5,000 m3

    For canvas work you don't need a industrial walking foot machine. Any old all metal domestic with a 4-5mm zig-zag will do. My favorite would be a Necchi BU like this one: http://www.gumtree.com.au/s-ad/kirri...ine/1133869032 It's nowhere near you but the price can't be beaten. Old Necchis are almost always undervalued because people don't know them. They only heard of Singer, Pfaff and maybe Bernina, never of Necchi, Janome, Toyota, and others.
    If you like to spend money buy this one, it's a sailrite: http://www.gumtree.com.au/s-ad/kawun...ine/1138499933

    For the cabin I would go for the plywood option. It gives you a leakfree substrate you can then veneer with your choice of wood. You probably could do everything out of your mahagony plank, maybe even the interior if you can slice it thin enough and reduce waste. All matching of course.

    I've been looking at sewing machines too, for sail covers and the like. As far as I can tell industrial machines just go really fast. As suggested above, many older home machines will do the job just fine.

    Larks, I had to learn the hard way. As a result of all that effort I try to make things easier for my peers. Have you chosen an engine yet? I am still seeking one for "Bright Star" without having made a final choice. I am leaning towards the Kohler as it is light.

    I’m still waiting on a price for the Kohler/Lombardini Jay, so at the moment I’m leaning most heavily towards the Yanmar 3YM20. It is bigger and heavier than the Kohler but similar weight to the old Volvo 2002b that I took out, is actually coming in reasonably competitive on price and the Qld head office is very close to home.

    The owner of the marine engineering company that I used to manage is in the process of taking over the Kohler distribution so I’m expecting to get a pretty good price out of him.

    Jay, since posting the above I’ve received a revised “boat show” price on the Nanni 3.21 and the price on the Kohler (Lombardini) LDW702 and have gone from getting excited about the Nanni (because of price and inclusions) to getting excited about the Kohler because I can get it at an exceptionally good price compared to normal retail (through my industry contacts).

    So I’m now bouncing between the Nanni and the Kohler, each has different benefits -

    - the Nanni is 3 cylinder so should be smoother running, but the 2 cylinder Lombardini is supposedly more modern technology so possibly as smooth running;
    - there is only 7kg difference in weight
    - the Kohler has a 120amp alt v the Nanni at 70amp, but the Nanni (if I am reading it correctly) has an option for a boiler to be installed using the heat exchanger - (I’m still trying to work that one out - this is the comment in the product blurb: "The latest generation heat exchanger im-proves the temperature regulation, whichquality can particularly be appreciated when aboiler is installed. “)

    We heat water from our Yanmar, works well. Hard to know what mr Kohler is talking about though. You heat from the engine coolant, which should be temperature controlled by a thermostat. And I think you might be talking amps, not hp on the alternators.

    The engine in "Bright Star" was Universal Atomic 5416 twin diesel that produced 16hp and weighed in at 365lbs/165.5kg.
    I have always wished the engine were lighter in weight. It was installed in the 1960's and gave good service but, even though it had a head exchanger, it gave up to a perforated water jacket and was unreparable. We considered the Yanmar but, I still want less weight in the stern. It looks like the Kohler/Lombardi will be the one I will take. It produces 18HP, two more HP than the old engine and it weighs in at 99kg/218lbs which is 147lbs lighter than the old engine. That makes an amazing difference to my thinking!
    Thanks for the reference to the Kohler/Lambardini Diesel Larks!

    I can't remember whether I know what work you are doing in Darwin, but if it's one of those top secret Navy jobs you might want to go back over what you did yesterday
