In the instructions, the before illustration is very thin compared to the after drawing on the right.
There is a slight taper sanded into the outside edges to better fit the "Q" side pieces coming up.
After sanding in the angle,
Here's the "Y" piece, lightly glued into the slot in the "X" piece.Glue lightly, you may want to have it held like a glue "hinge" so it can be moved slightly for a better fit of the "Q" side pieces.
On a dry fit, no glue yet -
You can see the gaps in the "Q" side pieces.
Mirror the other side.
On the right is the other side. You'll have to do some dry fits to figure out which angles are sanded into which sides. The instruction drawings are confusing.
The geometry of the joints of these pieces does get a bit complicated. The bevel for the long edge of the Q parts is pretty straightforward, as the majority of the base section. The tricky bit is the pointy end that intersects with the *inside* of a "V" joint means the bevel angles are reverse of the rest of the base.
ReplyDeleteHi Naoto,
DeleteYou explained it better than I could!
One thing that I bet will probably confuse some folks is the curved edge on the base of the fin where they connect with the cylindrical airframe. Although shape of the fins consist of flat planes -- they intersect the body tube at various angles, so the shape of the intersection may not be straightforward.
ReplyDeleteHi Naoto,
DeleteThose curved root edges might throw off a new builder. They do make sense when set on the body tube.
