      I believe the only addition to perfecting this further, is adding a couple of drops of varnish in the predrilled screw holes before setting in the screws. Thus further limiting the remote possibility of any water ever entering and damaging the wood through the holes. Just my 2 cents from my late dad and I. This is beautiful meticolous work! And I really appreciate the zen pace!

      I will wax the bronze before it’s in the elements. My experience with protective coatings (X-I-M 900 clear coat I found to be the best) is that they are only good for so long. Then one has to strip the old coat off, polish and re-coat. I think much easier to just re-polish and wax each season.

    • @mattlewandowski73
      @mattlewandowski73 2 ปีที่แล้ว

      With the 3d printers, you can do lost wax, lost PLA, or PLA pattern mold casting. Each method has its advantages and disadvantages. Resin printers have similar options available with even finer detail available, but are limited to smaller pieces. They can however do bulk prints easier... Then there is laser sintering which can process small bulk jobs easily but the printers are not really available at a hobbyist level, though a number of companies are offering print services. Both resin and laser sintering are excellent for smaller hardware pieces that you need a number of. Yes... 3d printing is absolutely the future of metal and ceramic casting.

    You make every task on this boat extremely enjoyable to watch. I’m a hobby woodworker and in the past, when I have had to taper a workpiece, I have always started at the (smaller) end and planed increasingly longer segments from that end to the other (larger) end of the taper. Kind of hard to explain, lol. It seems in the video that you worked from the larger to the smaller end of the taper. Is either way OK, or should I,switch for best results. Can’t wait to see the mast. I’ve watched A to A do theirs and will be standing by for your version. Best regards!

      @@petterandersson7429 hollow would be great for weight, especially for a removable mast for transporting the boat to and from home to water if it won't be left water-side. Also, hollow is great if any electronics like a mast top light or nav-sensor will be in play. Solid would be stronger, but as you said, would be heavier. It would also have its negatives to portability of the vessel. Having to raise and lower the heavier solid mast for transport would definitely be a negative.

    Beautifully done, Bob. Sure would have liked to have seen how you rounded that egg on the fore end of the boom, but, oh well. Everything looked like it fit pretty well. Any more filing on the bronze, or fitting the boom to the bronze, when the time came?
    Did you drill for the screws then soak the screw holes with varnish or some other sealant before mounting the hardware?
    I feel these are important questions for the longevity of the wood.

    Hey Bob, Just out of curiosity, I thought that extra metal that is the gate shaped like a H is for a purpose. I noticed you ground that metal out, I believe it is not just a gate but it is there for reinforcement of your work pieces. If you ground them out won't that weaken the work pieces? Of course I could be wrong but that is my thoughts on the matter, what do you think? what are your thoughts? Nice work! Bob. As always.

    • @TheArtofBoatBuilding
      @TheArtofBoatBuilding  2 ปีที่แล้ว +1

      Hi Fon, the H you're referring to is just a gate for the metal to flow into the part. It doesn't have anything to do with the strength of the part. If you look at the plans it does not show that on the finished part. Adding it was purely Steve and my invention to make gating easier on these small parts.

    I would go for a slightly longer boom. Spars are notorious for being too short and most (all?) rules call for maximum length of leech/luff of sail, not the spar itself. Leave an extra couple of inches will give you some room för a trim adjustment configuration that won't be totally crambed out on the far edge of the boom

      The original design for this boat was done 108 years ago by N.G. Herreshoff, The great yacht designer. In 1985 another yacht designer of note, Joel White, designed the Haven 12 1/2 off of the Herreshoff 12 1/2. Changing only from a full keel boat to a centerboard sailboat.
      I've been following all the critical design elements as designed! Thousands of these boat have been built and sailed with the 11'-11" boom for over one hundred years. I have had the pleasure of sailing both a Herreshoff 12 1/2 and a Haven 12 1/2. With all do respect I must disagree with your suggestion. However, when or if you build a Haven 12 1/2 you can do what you like.
      My boat will follow a long tradition of a very successful boat, and "is nearly universally acclaimed as one of the finest small boats of all time."

    I was wondering if you'd do lost PLA some time. Most of the shapes seem kind of simple & geometric, probably as easy to make the old way as any other, or in lost wax. Still, lost PLA is a really cool way of producing complex, repeatable parts. I think you would be better to make the layer height smaller to reduce the layer lines - the stepping visible in those prints.

    • @TheArtofBoatBuilding
      @TheArtofBoatBuilding  2 ปีที่แล้ว

      Not sure what you mean by (wondering if you'd do lost PLA some time) These part were cast by Lost PLA. Are you asking for a more detailed video on the process? These small part where perfect candidates of the PLA process. Small parts are hard to cast in sand casting and geometric shape are difficult to produce with out an intermediate mold from a part. The layers are an unavoidable part of the 3D printing. However, the PLA is easily sanded smooth before casting.

Most lost PLA castings on TH-cam usually involve complex parts or sculptures where design & repeatability is a requirement. e.g. Robinson Foundry channel does a lot of them. I was wondering here if you chose lost PLA for a reason over wax since the parts looked like they were fairly geometric and could have been done that way.
