## Article: Building the J Class Endeavour Model (1:80 Scale)
# Building the J Class Endeavour 1934: A Beginner’s Guide (1:80 Scale)
This guide walks you through building a 1:80 scale wooden model of the 1934 J Class Endeavour using the plank-on-bulkhead (POB) method. Designed for beginners, it uses the provided vector plans and common tools like a hobby knife, sandpaper, and glue. The process is broken into clear steps to create a display-worthy model.
## Step 1: Prepare Materials and Workspace
Gather materials listed (basswood, plywood, brass, etc.) and set up a clean, well-lit workspace. Print the vector plans on A4 paper, ensuring the scale is 1:80 (480mm length). Cut out bulkhead and keel templates.
## Step 2: Construct the Hull Framework
Trace and cut 10 bulkheads and the keel from 4mm plywood using a hobby knife. Sand edges smooth. Glue bulkheads perpendicular to the keel at 20mm intervals, using clamps to hold until dry (4–6 hours). Check alignment with a ruler.
## Step 3: Plank the Hull
Cut 1mm basswood sheets into 5mm-wide strips. Glue strips to bulkheads, starting at the keel and working upward. Bend planks gently with warm water if needed. Sand the hull smooth after planking.
## Step 4: Add Deck and Fittings
Cut mahogany strips for deck planking and glue to the plywood deck base. Sand and varnish. Add brass fittings (e.g., cleats) using a pin vise to drill holes. Paint the hull white with brown accents.
## Step 5: Rigging and Sails
Sew cotton cloth into sails using the plan’s dimensions. Attach to masts (mahogany dowels) with cotton thread for rigging. Secure masts to the deck at marked positions. Varnish for durability.
## Tips for Success
- Work slowly to avoid mistakes.
- Test-fit parts before gluing.
- Use online forums like Model Ship World for troubleshooting.
Your Endeavour model will showcase the yacht’s elegance. Enjoy the process and share your build online!
