Instructables
This instructable is to build a 3d pantograph. A pantograph is a device that is used to copy pictures by tracing the original picture and the device draws a copy.  The pantograph can change the copy size to larger or smaller, depending on how it is designed.

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.

Parts needed:
  • 1 - 1"x4" by 10 foot pine board.
  • 1 - 3/16"x36" metal rod
  • 1 - Rotary tool (such as a Dremel).
Remember a 1x4 board is not exactly 1x4 but about 3/4 by 3 3/4. I will refer to the board as a 1x4. for simplicity.
Optional:
Tools needed:
  • Saw
  • Drill
  • Hole saw 1" and 2" or depends on the size of your rotary tool. rotary tool.
  • 3/16 drill bit
  • Hammer
  • Hacksaw
Optional:
  • Wood Clamps
  • Nail Gun or Wood Glue
Difficulty: Easy-Moderate.
Time to build: 5 hours.

Update: Skip the woodglue and countersync all the screws. I made this in about 45 minutes. Works fairly well, Im trying some modifications to control the Size ratio bettter as I would rather have about 3/5th ratio on mine.

I am gonna give this a try sometime this week its def different from the woodgears.ca pantograph but I dont want to spend $12 for their plans and another pain in the ass to use thier printing program and cad. ill repost when I finish and test. thank you.

how do you make a 5" square on a 4" board? makes no sense.

Hi can you tell me if this is the same as Mathias wandel pantograph
Very nice. I like how this is designed for a dremel, and a heck of a lot cheaper than some other ones I seen. One question though, as you have it built, what is the scale ratio? Is it exactly 2:1?

This is 1/4 size. I have been carving wood and glass about 4" square of a pattern made on a 8x11 paper.

Another one I have been working as part of a design refinement is a 1 to 1 ratio.

The Pantograph has been around for a long time. Using a Dremel allows me a lot more flexibility with the medium I am working with than something bigger such as a router.

Now that I have a better glass bit to use, my results are a lot better than what I used in the pictures.
I had to look up what a pantograph was, pretty cool. Great work.
