Intermediate Wood Handle Ob Bottle Opener

Software:

Chilipeppr

Machine Time:

~1 hour 15 minutes

Bit or Laser Size:

Maple and Black Walnut

This bottle opener was made using curly maple and black walnut which was laminated together using gorilla wood glue, clamped and allowed to dry. To ensure that the blank was of even thickness I surfaced a section of my spoiler board and proceeded to "Plane" the stock on both sides. If you don't own a surface planer using your router/mill for small projects is a good alternative. Over all machine time was about an hour and 15 minutes, but could have been considerable faster with a spindle that allowed for greater than 12000rpm. The circle around the logo was machined using a 1/8" 90° carbide v-bit. For the logo I used a 1/8" two flute upcut endmill for clearing the majority of the pocket, and cleaned up the details with a 1/16" two flute ballnose endmills. The parimiter was cut using a 1/4" Mortising router bit. I had to use such a large diameter for the profile cut because the thickness of my material exceeded the effective cutting length of my other tooling.



The design and tool paths were generated in vectric aspire (it was a pricy investment in the begining, but it's user friendly interface and ease of use makes it a very effective tool for people just getting into cad/cam). I will be sharing the Dxf files in this project shortly after I clean them up a bit. I found a few mistakes durring the machining process.

A belt sander and palm sander were used to finish the bottle opener with sand paper grits of 80, 100,150,250,500,1000 being used in that order. The final product is smooth to the touch and offers a high luster finish after I buffed it with a bees wax/mineral oil paste and 0000 steel wool
