Hi,

heard of a method of shaping foils by constructing a jig for a router.
Anyone done this or have a link for some pics?


I've used a table-saw with a dado-blade and a NACA foil template for setting
the blade angle and height. I use multiple longitudinal passes, stopping
short of the end of the stock to leave the top squared off for easier
attachment to the rest of the rudder assembly. a Here's what the template
looks like:

And here's a comparison of using that method vs a router:

And the last rudder blade I built using the method:
