How to Make a Wooden Sled with a CNC

This is a relatively complex project. We recommend that you tackle it after you've gained some experience with CNC milling.

The sled is made from 17 pieces of plywood, which are glued together. At the end of this tutorial you will find all the technical files you need to build your sled (Fusion360, Gcodes).

 This is the maximum size that fits on a S size Mekanika CNC.
If you feel comfortable with Fusion360, you can modify the project to make is bigger!

The sled is made up of 17 pieces that come from 3 sheets of plywood. So we have 3 Gcodes. 

• Setup 1 : Vertical legs and long seats - 600 x 630 mm stock.
• Setup 2 : All seats and backs of sliders - 530 x 650 mm
• Setup 3 : Bent side of sliders - 560 x 630 mm

We used pine plywood for our sled, but you can use any material you like for this project. Please keep in mind that the project is designed for 18mm thick material and all parts fit together. If you decide to use a different thickness, you'll need to modify the Fusion 360 project by redrawing all the joints.

We used a 6mm 2-flute end mill to mill our parts.

You can also edit the Autodesk Fusion360 project to use a different end mill, for example.

Each setup is made in the same way, we used panels of the sizes detailed earlier, screwed to the spoiler board.

Everything was milled with a 6mm downcut end mill and the spindle should be set to run between 20,000 and 25,000 rpm as the feed rate is 2760 mm/min.
