This pantograph will let you carve or engrave a picture into a medium such as glass, metal, or wood. You can also trace a carving and reproduce it. It uses a rotary tool such as a Dremel to carve. Think of it as an old fashioned 3d printer.
This pantograph can cost between $15-$50, depending on what kind of rotary tool you buy.
- 1 - 1"x4" by 10 foot pine board.
- 1 - 3/16"x36" metal rod
- 1 - Rotary tool (such as a Dremel).
- Router Speed control. If your rotary tool is not variable speed and it spins to fast, you will want to consider this. You can buy one for about $20 here. http://www.harborfreight.com/router-speed-control-43060.html.
- Hole saw 1" and 2" or depends on the size of your rotary tool. rotary tool.
- 3/16 drill bit
- Wood Clamps
- Nail Gun or Wood Glue
Time to build: 5 hours.
Step 1: Cutting the Wood and Metal Rod
Take one of your 1"x24" boards and cut in half to make two 12" long boards.
Cut one 1"X24" board down to 18"
I rounded the corners, which makes it look nice but it is not needed.
Cut 2 24" boards from the 1x4. On each one, mark the middle of the board and draw a square 5" in the middle. Cut down to 1 inch wide on either side of the 5" square, as shown in the illustration. Save the cutout parts as you will use them later.
Cut from the 1x4 several pieces.
4 -7" Pieces
1 - 17" Piece
3 - 2" pieces
Using a hacksaw or rotary tool, Cut the metal rod into
- 4 - 7" pieces
- 1 - 9" piece
Step 2: Drilling Holes
Drill in the end of each wood a hole 1/2" from the end
On the 18" and 24" board, pair them together and drill the holes 1/2 " from the end and 11 1/2 " from the end.
Step 3: Drilling Holes for Tool
Depending on the size of the rotary tool, on the top board drill a 2" hole in the middle, 1" in from the long side. It will cut through the side of the board and needs to go all the way through.
Later you may need to size these with a knife (or the rotary tool) to make the rotary tool fit.
Step 4: Assembling the Boards
Assemble the 12" and 18" sections the same way.
The open area at each end is necessary so the pantograph can move around when assembled.
Step 5: Making the Pantograph Pivot
Cut one of the remaining pieces from the 9.5" by 3 pieces into
- 2 - 6" piece
- 2 - 2.5" pieces
- 2 - 1" pieces
- Build a U out of 1 6" piece and 2 2.5" pieces. Nail or glue them together.
- Drill a hole 1/2" from the edge in the middle of the U on both end pieces.
- Drill 1 hole through the bottom of the board all the way through on one end piece.
- Drill a hole in the end of the two 1" pieces
Place one 1" piece on each side of the U where you drilled the hole. Connect the three pieces together by hammering a 7" rod through the hole. The fit should be tight.
Using some screws connect the 1" piece to the final board. This would be one of the scrap boards (9.5"x3") left from when you cut around the 5" square. The end where the rod is sticking through needs to hang over the board so it can move around.
Step 6: Assembling the Tool Board
Place the final 2 7" boards horizontally on the sides of the cutout.
Step 7: Assembling the Pantograph
Use a hammer to push a 7" rod into each remaining piece. The fit should be tight, but the pieces should be able to move around.
Once all connected, it will look like this.
Step 8: Building the Tracing Stylus
In the section that has a 18" top and 24" bottom, drill a small hole in the end of the long arm and screw in a 3" screw. Place the pointed wood into the end of the screw.
Using a three inch screw will allow you to change the height of the rotary tool for cutting/ tracing different types of material.
Step 9: Placing the Roatary Tool
Step 10: Setting Up the Pantograph for Use
Move the pantograph around to get a feel of where you want to place your pattern and your material you will be cutting.
Tape your pattern on to the board where you will be working.
Taking some scrap wood and screws, lock down what you are carving so it is positioned under the engraving bit.
My Folding Garage Counter was perfect to work on for this project.
Step 11: Start Engraving
Here are some first pieces I cut.
