I created this excercise in 2014 to:
click to view movie
cutting and backing parts onto bristol paper
paper form
packing the paper prototype form in clay
- I used 2x lamination so the parts stay together better until they're encased in clay
hours later... symmetry checked and edges smoothed - hull's form is complete
building the balsa parts from the vector plans
closeup showing how to pin wood
- always dry fit the pieces before gluing
- ensure it lays flat
curved spine
- the spine is constructed from 6 pieces which are later sanded to a smooth round curve
- ensure the ends are cut and sanded nicely before gluing to ensure the spine is as strong as possible
removing a part
sanding
- flat side, round corner
making the wood skeleton
mast is held firmly between ribs 4 & 5
wood and clay forms
vacuform testing the heating time with Petg plastic on various materials with different textures
- air pockets cause puffing
- metal causes loss of detail because the plastic seens to cool quickly before sucking into the details
- some plastics melt when the heated Petg contacts them
another coat of clay to make it perfect
done
darn it
fixed with plaster
vacuformed hull
new balsa skeleton
all parts
- the magnets on the hull, keel, skeleton, and rudder aid in assembly and hold the boat together
sailboat assembled
- sail is light-weight and adjustable
- sail+mast+boom are removable
- adjustable rudder that stays where you angle it
- balsa skeleton and keel are held firmly to hull with magnets
... the inspiration
