The easy way out is to have the core CNC routed, if you know of someone that got the knowhow and the machine. First you need a drawning in a cad version the cutting machine can read. The nice thing is that you know that both sides are completly alike. The spreadsheet can be used for such a drawning or for hand building as well. tell me if you want a copy by email.<BR/><BR/>I don't know if Ian has not provided you drawing of the daggerboard yet, but in my planbook there is a full how-to-do-it plan using normal foam and hi den. foam in the middle.<BR/><BR/>My site was started because i saw yours and other F22 builders using this blog form instead of a home page. This is very easy and it looks good too.<BR/><BR/>ThanksMartinFhttps://www.blogger.com/profile/17996305240765826651noreply@blogger.comtag:blogger.com,1999:blog-37035807.post-3353288993900413402007-02-27T08:52:00.000-05:002007-02-27T08:52:00.000-05:00Hello Martin,I was planning to use the profiles su...Hello Martin,<BR/>I was planning to use the profiles supplied with the plans. My thoughts now are more oriented towards the question, how to build a light but durable daggerboard. Your blog site is impressive. I'll be adding your site to mine as a link soon.<BR/>CheersAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-37035807.post-49134847447476860752007-02-26T16:56:00.000-05:002007-02-26T16:56:00.000-05:00Hi Grant I done some foils in my time and i got a ...Hi Grant <BR/><BR/>I done some foils in my time and i got a exel spreadsheet for calculating Naca profiles for naca 4 digit (ex. 0010), 64 series and 65 series. The two last is for higher constant speeds and is not so foregiving as the 4 digit. But I have done a 505 dinghy High aspect centerboard in naca 64 doing well. If interested please email me.
