The Crafted Elements Router Sled (Wood Slab Flattening Mill) is perfect for small wood shops and garage woodworking warriors that have limited space. If you don't have the space or money to buy a large CNC machine ($10K+) or industrial planer ($70K+) then a router based slab levelling jig is a great solution.
Our router sled is built with industrial grade 20mm components commonly used in CNC machines, large 3D printers and industrial automation. We precision cut and machine 1/2" thick acrylic components for the cross rail brackets and router mount to create a durable, cost effective solution that is going to save you time, money and boost shop efficiency.
Save shop space with the easy to attach and detach linear rails. Once the initial assembly is completed, the router carriage (sub-assembly) and rails can be setup and ready to go on your existing flat and straight workbench within 2 minutes.
The Crafted Elements Router Sled jig comes with everything you need except the router, slab flattening bit, plywood rail risers and workbench. Use any compatible full sized router with a range of commonly available spoil board (slab flattening) bits. The router base plate features pre-drilled holes for most commonly used routers, making assembly that much quicker. We also offer a blank "drill it yourself" base plate if you have a router that isn't in our compatibility list.
The router sled is available in lengths of 4', 6', 8' (2 sets of 4' rails) and 10' (4'+6' rails) with cross bar widths of 40", 48" or 60". An optional dust collection shroud and 2.5" boot is available to help catch some of the dust created by slab milling. We also have a smaller, 36x32" router sled kit designed just for trim routers.
The size of the Crafted Elements router sled represents the approximate footprint of the sled components when assembled and reflects the workbench area required to mount it. The slab flattening area for each size router sled when using a 2.5" diameter slab flattening bit (like the SpeTool CA-IP-D1/2)* is as follows:
| Router Sled Size | Maximum Slab Flattening Area* |
| 48x40" | 39.5x30.25" |
| 72x40" | 63.5x30.25" |
| 96x40" | 87.5x30.25" |
| 120x40" | 111.5x30.25" |
| 144x40" | 135.5x30.25" |
| 48x48" |
39.5x38.25" |
| 72x48" | 63.5x38.25" |
| 96x48" | 87.5x38.25" |
| 120x48" | 111.5x38.25" |
| 144x48" | 135.5x38.25" |
| 48x60" | 39.5x50.25" |
| 72x60" | 63.5x50.25" |
| 96x60" | 87.5x50.25" |
| 120x60" | 111.5x50.25" |
| 144x60" | 135.5x50.25" |
8' (96") long router sleds include two sets of 4' (48") linear rails. 10' (120") long router sleds include a set of 4' (48") and 6' (72") linear rails.
The maximum slab thickness is determined by the number of risers (if any) used to mount the side rails, the length of your router bit, and whether or not you are using a 1/2" collect extension. See the assembly and instructions video below for a full explanation.
Have a small shop or work area and are doing projects bigger than what a 12" planer could handle, but don't need one of our full sized sleds? Our 36x32" trim router sled is something you should check out.
