I want to shap a double V on my 6'5'' egg? http://fluid.kajakworld.at/fluidworld3/surfboard/41.jpg Want to ride a thruster setup...is there a general rule where to put the fins? which angle to the stringer and how much do you tilt the sidefins? I've almost finished shaping my first board...my floodlight broke down when I was going to clean up the rails...but it's already 3:05 at night...will have to wait till monday when I can buy a new bulb. [frown] Any shaping advice is appreciated btw [smile]) it's now 2.34'' thick and does look a little different... cheers Marcus http://fluid.kajakworld.at/fluidworld3/surfboard/surfboard.htm

Is osama hiding in your shaping room?? looks like a dungeon!!!haha
Hey What exactly IS a double V? Most boards are just a V off the tail, starting just behind the wide point. I'd assume a double V is a quad panel.
I have an old LocalMotion that is shaped this way...maybe it's called a double concave? It's two...one between each side fin and the center fin. What does it do? I want it cause one of my other boards has it and I like that board most...but maybe it's something else about the baord anyways. http://fluid.kajakworld.at/fluidworld3/surfboard/surfboard.htm
nice photos! http://fluid.kajakworld.at/fluidworld3/surfboard/22.jpg http://fluid.kajakworld.at/fluidworld3/surfboard/22.jpg
Marcus, Its looking really nice!
Hey OK, double concave. I didn't shape many in my day, but did a couple of deep single concaves. You might mark with a pencil (lightly), the exact spot you want maximum depth. Then mark the shallow concave area, then the least. Take a planer and do one shallow, 1/16th (but depending how deep you want) cut. Take two passes with a surfform length wise up the center. Take one each pass on either side of that pass. Take one or two passes on the outside of the planer cut. Now you've got the grooved pattern located in the app. spot, app. depth. Sanding now, you can feather in at 45 degrees, in a cross pattern. Some guys like sanding the inverted curve, with paper backed with softwood in a curve. But you gotta make that. Use new paper, always dump it out before it gets worn. Your sanding block has soft, relieved corners, right?
Thank you. I had to shape the deck down 1 cm (its 6cm now)cause it looked too thick...maybe I am just to fixed on the look of shortboards. It still needs a lot of shaping...some curves don't belnd in so well now. It's my first board but I won't stop until I am satisfied with the board. Next time I know that I can hotwire the blank to a closer toleranze...thinner and don't need two blocks of XPS but one will do if I place the halves good over each other... But still...what about the V? Which bottom design should I use? cheers Marcus http://fluid.kajakworld.at/fluidworld3/surfboard/surfboard.htm
thank you. Where do you place fins? does it depent on the overal lenght or the position of the back foot? which angles? Is it ok to just copy fin setup from a 6.6' shortboard that rides well? I always wonder if shapers calculate the fin placement? http://fluid.kajakworld.at/fluidworld3/surfboard/surfboard.htm
Hey Oops, now we're changing the bottom design? You can shape it however you want, but you probably should decide soon. Er......aren't your rails already shaped to a curved, almost final finish? The bottom shape might have to stay as is, depending on how much of the outline you have already shaped. For instance, adding V in the tail requires you to lift the tail rails up about 1/4", and if the rails are already curved and finish shaped, it won't happen without messing up your template. Fastest bottom shape is undoubtedly a flat nose to slightly accelerating V going right off the tail.
oops..then it will have to stay flat. don't know...it's so hard to decide with so much design options... I guess I will have to start a second board next week...right. Don't mind...I have lots of friends that are into surfing. Fins: I will just copy what my thruster features. thank you. http://fluid.kajakworld.at/fluidworld3/surfboard/surfboard.htm
