All Slab Mills Sold out!
We are only offering the accessories listed above.

The hottest trend in interior design these days is live edge slab table tops. And, why not? The natural curves of the trunk give an organic feel. The crazy grain patterns in crotches and burls are eye-catching. Even cracks that would have sent lumber to the burn pile just a few years ago are being controlled and enhanced with butterfly patches and epoxy inlays. However, slabs present some challenges in the shop. Overall width and weird grain changes make the use of a jointer and thickness planer impractical if not impossible. If you just tear into it with a belt sander you will eventually end up with something that is somewhat smooth, but not even close to flat. And who wants a table that isn’t flat?

Woodpeckers Slab Flattening Mill (along with your router) lets you accurately and easily flatten oddly shaped and oversized slabs right in your own shop. Since you’re using a router instead of a planer-style cutterhead, tear-out is minimal…the surface will only need light sanding afterwards.


Woodpeckers Basic Slab Flattening Mill can be mounted to any flat and level work surface in just a few minutes, even a simple sheet of MDF. With this setup, you can easily flatten slabs up to 38" wide by 57" long. The Extended Slab Flattening Mill expands the capacity to 62" by 105" or 38" x 129".

The Extension Kit includes two 72" rails which can be coupled to the base rails for longer pieces or swapped with the cross rails for wider pieces.

While expanded capacity is great, you’ll also appreciate that the whole assembly can be condensed down to work on cutting board and end table sized projects without reaching across a vast stretch of unused space.

The Slab Flattening Mill can handle rough workpieces up to 3-7/16" thick. You can mill thicker pieces, but you have to make and use some riser blocks to add capacity.

Using the Slab Flattening Mill is as easy as sliding your router across the slab and back, moving over a little less than the width of your cutter and repeating until you’re done. It comes with all the hardware you need to mount it to your workbench or a sheet of plywood. You’ll also get 4 Slab Clamping Dogs that keep the workpiece firmly in place.

Extension Kit Includes:
  • Two 72" rails
  • Assembly hardware
  • Does not include plywood or MDF base.
Router Bits

The Slab Flattening Mill can be used with a straight bit, but it really works best with a Spoilboard Surfacing Bit, which will leave a smoother surface and mill a large surface more quickly.

Compatible Routers

The router carriage of the Slab Flattening Mill is pre-drilled for the routers below. If you don't have one of these routers, you can use others, but you'll need to drill mounting holes. The mill works best with routers 2-1/4hp and larger.

  • Porter-Cable 890, 7518, 7519 & 7539
  • Festool 1400 & 2200
  • Triton TRA001 & MOF001
  • Bosch 1617EVS (fixed base only) & MRC23EVSK
  • Milwaukee 5616 & 5625
  • DeWalt 618B3, 621 & 625
  • Makita RF1101

So if you’ve been holding off tackling a live edge slab project because of all the challenges, you just ran out of excuses.

All Woodpecker tools are machined in their shop just outside Cleveland, Ohio.
