![]() ![]() The software is made for both Mac and PC and provides a 3D environment to design surfboards. It is really easy to use and lots of fun. The AKU shaping software is the software that was developed to use with the AKU machine (but you can use it without buying the machine too). The AKU is a machine used to ‘machine shape’ a surfboard blank. AKU Shaping Machine AKU Surfboard Shaping Software Thanks again everyone for the input, it's all good.The AKU shaping software is a fun tool to use to throw together some surfboard shaping ideas. My thought is that this will allow some experimentation on fin design while keeping things fairly simple to build and change. Currently I'm planning a single fin in a 10" box. Sheathing will be a single layer of 4 oz S glass set in epoxy. I like the idea that this wood is getting a second lease on life, for something more dignified than landscape timbers or firewood. The wood for the planks was salvaged from some old redwood water tanks, and is tight grained, clear heartwood. Rails will be hollow bead and cove, per the Grain method. I gotta learn to walk before I can run, and if this build goes well, then there's plenty of lumber on the woodpile for the next one.Ĭonstruction will be with 6mm Okoume ply fishbone, planked with 1/4" redwood. This board will not be the ultimate high performance surfboard, but more of a small wave assault vehicle. All this complicated by a nice swell arriving yesterday.Īmbrose, I am on the same wavelength with you on float, glide and SUP as surfcraft, fitness machine and peak to peak transportation. Final coats of varnish go on the paddle this week, so the board building will start in earnest soon. Thanks for the input all, keep it coming. If I were to squeeze a bit of volume out, where should it come from? Make the board a 1/4" thinner over all? I gained some volume by making the deck pretty flat (suggested by many for paddling comfort) but perhaps it should only be flat in the sweet spot, and be more domed fore and aft. Dimensions and shape come from boards I've seen and ridden, and from folks that know a lot more than I do about board design, especially stand up boards. I've been pondering the volume a bit, keeping in mind that there needs to be reserve buoyancy to keep the deck above water. I definitely have the glide in mind for this first board. As far as intended use, I'm thinking Cowells-38th-Privates kind of thing, a peak here and there, and move on to the next spot. ![]() Some years ago when my wife and I were on Kauai, a nice guy named Ambrose loaned us some nice single fin boards. I would love to take you up on the offer to try some different boards, but there is a big ocean between where you are and where I am so I don't think I'll be able to any time soon. though looking back some of the answers are PMs not the thread, but none the less still some good info there. There is some good design info in the "SUP design basics" thread. If you still have excess volume thin it out a little. If it is mainly for surfing I'd cut it down to 10'6". ~170# + 30# for board = ~200# -> (google conversion: 200 lbs to kg) 90.7 KG = 91 liters.įigure in maybe 30-40% reserve and your looking at between 118-127 Liters. I would agree, looks like way more reserve volume than you would need. Agreeable that the math is rough, but still, that's an awful lot of float. somehow I don't think you want that much. If the board itself is 30 pounds that leaves 290 pounds of float. 3.785 liters to a gallon so heck say 4 liters per gallon, you've got about 40-odd gallons (volume) of buoyancy, and if a gallon is about 8 pounds that's 320 pounds of buoyancy. My metric conversions are a little sketchy but let's see. ![]() Quote: 173 liters sounds really corky to me.
