Pirate Pad Lock
Dale C. Mathis designs a functioning pirate pad lock.
Dale Mathis returns to make an actual functioning pad lock.
Materials and Tools:
2' x 4' sheet of 1/4" and 1/8" sheet of Masonite
5/16" and 1/8" dowels
2 small rubber bands
drill or drill press
5/16" drill bit
1/8" drill bit
temporary spray adhesive
black and silver spray paint
Note: The material for the pad lock was a two-part liquid plastic poured into a pre-made mold. Dale Mathis provided the following directions for making the pad lock project out of Masonite.
Consider the shape that would best fit the lock such as round, square, heart shaped etc.
1. Draw the pad lock shape on a sheet of paper and cut it out. Keep the drawing within 4" x 4".
2. Spray temporary adhesive on the back side of the drawing and place it on the 1/8 inch piece of 4" x 4" Masonite.
3. Wearing safety glasses, cut out another piece of 4" x 4" 1/8" and 1/4 inch Masonite.
4. You will have three pieces of Masonite:
- one 1/4 inch piece
- two 1/8 inch pieces
- one with the drawing glued to it
5. Spray temporary spray adhesive on each piece of Masonite. Sandwich the 1/4 inch Masonite between the two pieces of 1/8 Masonite with the drawing facing up.
6. Following the drawing, cut out the Masonite with a scroll saw. Tip: Draw desired pad lock design and glue it to your wood and scroll cut it out.
7. Drill a hole in the upper right corner with the 1/8 inch drill for the latch attachment.
8. Measure from the bottom center of the pad lock up 1 inch and drill a 5/16-inch hole for the key to the pad lock through all three pieces of Masonite.
9. After drilling, separate the bottom piece of the 1/8 inch Masonite.
10. Draw the teeth in for the key to the pad lock on the bottom of the 5/16 inch hole and cut it out with a scroll saw.
11. Separate the 1/8 inch and 1/4 inch pieces of Masonite.
12. You should have three different pieces of pre cut Masonite.
13. From another piece of Masonite make the latch to lock the pad lock. Measure from the center of the 1/8 inch hole on the right of the piece and to the left side of the piece and draw the latch. After drawing the latch, cut it out with your scroll saw.
14. Drill a 1/8 inch hole in the right corner to attach the latch and also don't forget to cut a notch in the left side of the latch.
15. Now focus on the center piece of 1/4 inch Masonite to make the inner parts of the pad lock. Most of it will be cut away with the scroll saw to have free movement of the trigger to lock the pad lock and for the key to fit against it.
16. Draw a trigger and side structures to support both the top and bottom 1/8 inch pieces.
17. Cut out what’s not needed with the scroll saw. Drill a 1/8 inch hole in the center of the trigger to give it the swinging ability to trigger the latch. Notch it so you have a place to attach the rubber band to create tension on the trigger.
18. Glue the both the bottom 1/8 inch pieces with all the center 1/4 inch pieces of Masonite.
19. Use the 1/8 inch dowels to make tension attachments for the rubber bands to hold.
20. Screw the top piece of the pad lock to the bottom of the pad lock, sandwiching the latch and trigger in between. Use 5/16 inch dowel to make the key. Spray paint the lock black and the key silver.
