For the demonstration, you will face a piece of aluminum stock, drill a hole in the center, ream the hole, and deburr all of the edges. Reference the video below to see what this should look like.

This video contains specific information for using the Mills in the Maker Hub as well as a basic overview of what will be expected in your live demonstration. {{#evu:https://www.youtube.com/watch?v=IJjXAxYH9TA}}{{#evu:https://www.youtube.com/watch?v=0190xVaZPNw}}'''Note''' that the tool changing system has been upgraded since this video was produced. To insert a cutting tool using the new system, push the collet upwards into the spindle with one hand and then push  the quill handle against the end of travel with the other to compress the spring in the tool change mechanism.  Make sure the quill lock is unlocked when installing or removing tooling. Pushing up on the quill handle will allow the the tool to slide up into the collet and the tool will lock in place once the handle is lowered. A decent amount of force is required to compress the spring so don't be afraid to push hard. Make sure to push the quill feed handle towards the machine to prevent the handle from disengaging. To release the tool, hold it in one hand while pushing up on the quill handle and then pull it out once the spring is compressed.  Never make contact with the cutter while inserting or removing tooling from the spindle.
