gozaimaas 61 Posted July 27, 2013 Author Share Posted July 27, 2013 A small radius is hooky and agile at slow speeds but requires skidded turns at high speed. Big radius is the opposite. Im playing with big sidecut radii now as im happy skidding turns at slow speed in exchange for laying train track style carves at maximum velocity. Last year i was straightlining that big groomer under the gondola (super east?) that is the type of speed i want to be laying carves at instead of having to skid turn. Its kind of the same reason as to why a dragster is 300" wheel base. Stability at speed, less twitchy etc. Link to post Share on other sites
seemore 66 Posted July 28, 2013 Share Posted July 28, 2013 and it wouldn't really have any effect in the deep stuff? Link to post Share on other sites
gozaimaas 61 Posted July 28, 2013 Author Share Posted July 28, 2013 Nope. Other than a long radius board generally being wider in the middle so therefore more surface area for a given length=floaty float float. Link to post Share on other sites

pdoull 2 Posted July 29, 2013 Share Posted July 29, 2013 Nope. Other than a long radius board generally being wider in the middle so therefore more surface area for a given length=floaty float float. Goz From previous threads I get the feeling you like longer boards for the more surface area/ more float. Do you ever go shorter / wider for the same effect? pros/cons with respect to riding pow? Pretty sure the quest is to tailor boards to get the best riding experience on Hokkaido Powder days. Is the 164 going to be wider? Link to post Share on other sites

Goz From previous threads I get the feeling you like longer boards for the more surface area/ more float. Do you ever go shorter / wider for the same effect? pros/cons with respect to riding pow? Pretty sure the quest is to tailor boards to get the best riding experience on Hokkaido Powder days. Is the 164 going to be wider? Surface area = float but is doesnt = performance on piste. To get a board to carve well (to my liking) it needs to have a longish effective edge and camber sections outside of the bindings, then to make it work in powder it has to have a long gradual upturn profile for the nose, this results in a long board. I didnt choose a length of 180 for the swallowtail board, its just what it had to be and it worked incredibly well. This year I am designing some shorter boards with longer sidecut radii which mean that they will have similar (still less) surface area compared to the 180 but the trade off will be traction and stability due to shorter effective edge but I am hoping to get some high speed stability back with the long radius sidecut. The hammerhead design is a 170 with a square nose to maximise surface area up front. If you look at that design its not a nose cut short, its a nose left really wide, if I trimmed the edges in it would look more like a normal board. In a world where nose float is everything I thought why cut material off? I should make it as big and wide as I can hence the square shape. This board also has 40mm taper from front to back which is pretty extreme. This board has less focus on groomer performance than my others. Im not even sure I will like it, buts its an idea I have and its worth a try. The 164 is pretty sneaky, Its a copy of my 180 birdman shape, 80mm off the effective edge, 20mm off the nose and 60mm off the tail (moon cut) but with big sidecut radius it gains back some of the surface area. Its going to be a split,so im chasing weight with its design, its smaller than i would ever design a solid for myself. I will also be making it thinner and using some carbon to stiffen it up I can throw around a 180 no problems so Im really not worried about going short like 99% of the snowboarding world is, I dont do park, I just like to bomb groomers and ride as fast as I can through the trees. Im pretty oddball lol so this is why I felt I should build my own boards. Link to post Share on other sites

Dunga 1 Posted October 16, 2013 Share Posted October 16, 2013 Firstly, thats a sexy piece of equipment there. What's the base made out of? Do you put p-tex or something like that on the base? Or do you go with the wood base as well. Link to post Share on other sites
gozaimaas 61 Posted October 17, 2013 Author Share Posted October 17, 2013 Cheers dunga. I use isosport 7500 sintered uhmw base material. Its really fast and actually better quality than any of the mass produced boards use. Here is a pic of it pre base grind. I just cleaned up the edges on the linisher and will profile the sidewalls tonight Link to post Share on other sites
