Introduction: CNC Bottle Opener
I made these bottle openers for the members of my Movember team. They were a thank you gift for growing their mustaches to rise awareness for men's health issues. They would make great gifts for anyone or just make one for yourself.
Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.
Step 1: Gather You Materials - Get Your Tools
Materials - 1/8" x 2" x 6-1/4" Aluminum bar stock
2 - 1/8" x 7/8" x 3-1/2" wood of your choice. If you use a laser or CNC to cut the handles start with a larger piece
2 - 3/16" Chicago screws
Tools - This is what I used. It is definately NOT the only way to make them. Since I had access to a CNC mill and a laser cutter I used them. The project could be made without either. Saws and sanders would work just fine. Since I was making multiples and I wanted them all to be the same, I used the CNC.
Techno CNC Mill
Epilog Zing laser engraver/cutter
Drill Press and Bits
Dremel with sanding drum
Step 2: Drill Holes
I decided to drill holes in the blank in order to hold it down. I did this so I would not have to worry about removing tabs later in the project. If you have a better hold down system (vacuum table) use that.
1. Mark the center-line
2. Layout hole locations
3. Center-punch marks
4. Drill holes - I drilled 9/64" holes so there would be no movement when the blank was screwed down and then redrilled them to the proper size for the Chicago screws at the end
Step 3: Mount Blank
I used 2 screws to hold the blank down. I found using a fence along one edge prevented the workpiece from racking during the cutting process
Step 4: Mill the Part
I used MasterCAM to to create the G-Code
Set up your mill
Run your program
I used dish soap as a lubricant to prevent the aluminum from melting and ruining your bit and project
I've attached a .pdf for those that don't have a CNC machine. You can print it out, transfer it to your stock and cut it out with a jewelers saw
Step 5: Bevel the Edge of the Opener
Use a Dremel with a sanding drum (or a file) to bevel the edge of the opener. This is necessary to get under the lid and lift it.
Step 6: Make the Handles
Use 1/8" wood
I used the laser cutter because I wanted to engrave the handles also. They could be cut in a CNC or made by hand.
