OK, so not really, at least not recently, but we do have to make 9 large ice cream cones - double scoop no less - for a couple of chocolate makers that also serve home made ice cream. This one is the size and engineering mock up. The "hand made waffle cones" will be laid up on the flat plastic, let to set up till stiff but flexible and then wrapped just like a real one. The ice cream scoop is actually one of the large Easter eggs - the green way to make displays - re-use Easter for Summer - eggs do go into ice cream, right?
We are slowly making fairing progress on the i550. Poor Dan spent another 4 hours on that dreaded long board today alone.
The bow is really "there". The small imperfections still present will hopefully somewhat go away with the glass and then the glass will need that little bit of fairing anyway.
The foam cores for the rudders came in. That are a lot smaller than what you would normally see for an i550 rudder core because they are inboard twin rudders. Flying Foam gets a nod for the high quality of the parts they provide. I did pay the extra to get the precision cut 3/4" dia. shaft hole placed while he was cutting the cores. It requires a rectangular hole at the end and a thin cut line down the length of the shaft, but as there will be carbon and epoxy over the entire things, those do not hurt anything. Besides, I am going to cut the cores into sections soon anyway.
The other thing those flat table "molds" will be used for is making some nice carbon fiber sheet material to cut into the foil sections. Those sections will be glued in between the cut up core so that the entire rudder is bonded to the shaft and the both outer skins. It makes the foam nothing but a material that helps produce the shape but not really needed for structure, though they will add a bit of stiffness.
