Intro: How to Build a Model Wooden Dinghy
This instructable serves as a guide to build a scale model of the wooden dinghy designed by Bob Darr, of Spaulding Boatworks in Sausalito, CA. Though the size is smaller, this process includes the same processes to build the full size dory.
Step 1: Materials
marine grade plywood
5 minute epoxy
Step 2: Making the Stem
Start with a solid piece of wood, 4 & 1/4 x 1/2 x 9/16 inches in diameter
Draw center line down the middle
Cut bevel lines on top and bottom. Top: 24 degrees, Bottom: 19 degrees
Connect bevel cuts with hand plane
Step 3: Make Bottom Side Planks
Cut two pieces of thin marine grade plywood, 2 x 40 inches in dimension.
Mark bow and transom bevels. Bow: 24 degrees, Transom: 22 degrees
Leave excess on transom side
Cut ONLY bow bevel
Mark stations at intervals of 12 & 1/16, 12 & 3/16, 9 & 5/8 from each other, starting at the bow.
Step 4: Make Transom Cleats
Make two transom cleats
Solid wood, 1/4 inch by 1/4 inch by 2 &1/8 inches
Bevel one side at 16 degrees
Glue in on transom bevel lines, inside of transom
Step 5: Make Transom
Use Marine grade plywood
Draw with following dimensions and cut with bandsaw or pullsaw
Step 6: Begin Forming Boat
Glue bottom planks to stem
Position boat molds so they line up with stations
Clamp molds to planks along stations, making sure everything is along center line.
Slide transom between bottom planks so it lays on transom cleats
Glue transom on
Step 7: Insert Thwarts
Place 3 evenly spaced thwarts (2 inches wide) in the boat
Cut notches in bottom plank
Cut to length
Step 8: Add Top Planks
Find top plank 1 & 13/16 x 40 inches
measure 3/16 inch overlap between top and bottom planks, mark difference
Use hand plane to cut gain and bevel on planks, so Bow is flush, stations are angled, and transom is straight and overlapped
Glue planks on, and tighten with wooden clamps
Step 9: Thwarts and Bottom
Glue in thwarts once top planks are on
Plane bottom till perfectly flat
Rough cut the bottom ply
Glue on and fasten with weights
cut oarlocks and glue on in front of front two thwarts
Create false stem.
make sure it is flush to original stem
add any artistic flair
enjoy your final product!
