Welcome back Herr Langford What secret bits did you smuggle back for the Sirocco?
The following extract from your construction pages (tail feathers): The tapered spars were created on the tablesaw with the same tapering fixture that the newletter printed a few years back. Simply put, it's a straight piece of 1x6 to which the spar is clamped using wooden clamps, at the desired angle. The angle on the blade was also gradually altered during tapering, so that the spars required no sanding to match the airfoil profile. This took an awful lot of thinking (mostly in mirror-mode) and ate up a lot of time, but was worth it in the long run. ++++++++++++++++++++++ Can you say a bit more here Mark. Any time spent getting this right will save gobs of time shaping and sanding the spars later (empennage as well as the wing spars), particularly with the AS sections. I am not convinced that what I am visualizing is right, i.e. - cutting a few inches; shutting down; changing blade angle; starting the saw; cutting a few more inches etc. You mention "required no sanding", so obviously no steps?? Would be nice if there was a way to progressively change the blade angle between the known angles during the cut. Take care Steve J
