Copying complex objects in wood

[Matthias], eminent woodworker he is, designed and built an awesome machine to make copies of just about any object imaginable. With a few scrap 2x4s, and a few bolts, screws, and skateboard bearings, you too can copy anything into a solid block of wood.

The theory of operations for [Matthias]‘ copy carver is mounting a router and ‘follower’ to the same piece of wood. Put that on an XY table with a rotation axis, and just about any object can be copied in wood or plastic. It’s not too dissimilar to a Dulplicarver, a routing machine meant to copy everything from gun stocks to guitar and violin bodies.

So far, [Matthias] has copied a rotary phone and a sadly non-functional wrench.  It’s the perfect follow-up for [Matthias]‘ 3 axis pantograph router that can copy and enlarge any random flat object you can throw at it.

A 3D Pantograph


It seems that there is no end to ingenious woodworking tools, such as this 3-D Router Pantograph from []. The pantograph, a design using linkages to trace and scale drawings, may have been invented in the 1600s, but if we were honest, most of us haven’t heard of this device. This particular pantograph is able to trace letters or other stencils in three dimensions by pivoting about an additional axis.

If you’re wondering where to get these stencils, they’ve got you covered with an online stencil generation tool. However, if you want to make even more detailed stencils, we might recommend using a free drafting tool such as Draftsight (here’s a review), or Sketchup.

[Woodgears] gives a good explanation of how it’s made in the video after the break. You can also buy plans for it if you want templates to use to cut everything. [Read more...]
