Are there measurements for making a rocker template? Are they measuremnts for natural rocker or do you make your own. I need help…Im trying to make a rocker template but have no idea what the measurements are. Also, does a Clark Foam blank come with markings indicating were the nose and tail rocker begin? Please help me out!!! Thanks Klein

Please help me out!!!>>> Thanks Klein You’ve wandered into one of the more difficult and closely held design areas. I won’t give give up any design formulas, but tell me what kind of board you want to make, some dimensions, what kind of waves you’re going after, and how you want to ride it. How much turning V are you planning? How thick do you want the finished foil. I can give you some matrix dimensions which you can hand plot onto roll paper, or directly onto your template material.

Thanks Noodle for the help, however I dont know if what I want to make is posible. First of all if you have been into the Resources page-Materials and tools section and gone to Australia Shapers they have a hand routing machine on there. I am wondering if the template they use for the rocker is pretty much universal. Do you just move the board foward and backward to put more or less rocker in the board. I am tooling around with the idea to try and build one but have no idea how to design the side templates. Any advice would be much appreciated. Thanks Klein
Klein, as far as I know, there would be a number of rocker templates for different blanks. Probably any time you wanted to change a rocker, or blank, it could require a new template.
In reference to the shaping jig you saw on the Australian website. The rocker templetes are all individually made and you have a different templete for eachbd. and each different blank you use, some are interchangable of course bu8t it will always be with a lot of tweaking and adjusting of the measuring scales (which is a job in & of itself). The outer templetes are made in pairs, one for each side and they are hand made & must be percise,(not a fun way to start your day especially if they are for a bd over 8’). I have used this type of machine and to be honest unless someone else is doing the work (to your spects) I don’tknow if it’s worth it, I can do it much faster with a planer and still be quite consistant with the measurements. As to the original question how is rocker done? There are lots of ways but the simplest is to come up with a length say 9’ & start at the center being 0’weigh it down (thin metal bar or 1/4" by 2" wood) and bend it up to the desired nose rocker(say 5") then measure back each 12" and add or deleate your curve —do the tail the same way, stablize the set up, put a piece of masonite next to it, trace it out, carefully cut it out and you have a rocker templete —place on your blank and compare to see where you need to remove foam-----you are now designing surfboards—good luck the ride is on!

Please help me out!!!>>> Thanks Klein I am making rocker temps. almost daily, I use thin paneling, cut into about 8" strips. With the help of a section on 8" aluminum angle to support it vertically, position it evenly up from nose and tail. For the initial rough out,take a pencil and elevate it on a block to pantograph the curve of the bottom. Saw this one out and redo the procedure with the temp. nearly even with the boards bottom. As it gets more accurate, just the pencil laying flat will come close enough to the true bottom conture. I do the same for the deck if I am doing a reproduction of the boards profile (this way I can make a magic board that won’t ride anything like the original) this is jokingly said as I have never reproduced a board that rode identical to the original. At least you have the rocker for a return to the original concept.
