im sure dimensions on these boards would have been discussed before but I can’t seem to find anything.
Im trying to do a template for the hypto at 5’8 x 20 x 2 1/2 but need the 12" nose and tail and rocker measurements. Also how far forward is the wide point bought on these? Always wanted one and super keen on starting my #2 :D
There are so many pics and dim-tables online. Load a rocker shot and an outline shot in boardcad or akushaper or whatever software you like and start copying. Never was copying easier than today. I’m not saying that you have a perfect copy of your desired board, but you can get pretty close by backyard standards.
Jordain, On a 5’-6" HK the wide point is 3-1/2" forward. At 1’ from the nose the rocker is 15/16" center and 1" rail. The 1’ from the tail is 13/16" center, and 15/16" rail. The center measurement is with the rocker stick on the center line. The rail measurement is with the rocker stick shimmed to be equal to the rails. The rail measurement gives you the rocker of the blank before you put in the center concave. I have a Excel file with all the dims of the 5-6 if you are interested.
Wingnut, I will try to put up a picture. In the meantime imagine that you are starting to shape a blank. You are just going with the rocker that is in the blank. At this point the bottom is flat, no vee, no single. The rail rocker is now the same as the center rocker in my terminology. When you start shaping in concave you are lowering the center of the blank with respect to the rails. The concave creates a rocker in the center that is different than what you had in the blank before the concave. To measure the rocker you need for the blank to have to start the shape you must temporarily fill in the places with concave to be level with the rest of the blank. Then you balance the rocker stick on top of the shims and make your measurments. It’s like if you look at the profile on a shaping program on the computer the center rocker will dip below the rails equal to the depth of the concave. Remember you only have to worry about doing this if you are trying to measure an existing shape with concave.
Hey Dave_D … mate, I understand the concept and, ah well, practical aspect that the rocker at stringer is different to that at the rail …
What I am struggling to picture, understand is how you measured the rocker at the rail … you used “shims”? I’m guessing you “packed up” either the rail (i.e. for where there is vee) or the stringer (i.e. for where there is concave) and then measured the amount of “packing” ???
I’m looking for more detailed dimensions of the hypto krypto for inspiring my first foam shape. Would anyone have it, as the excel file mentioned earlyer? Would even buy me oneto checkout how it’s features, but can’t find it here in Brazil.
