Beer Caddy
Advanced level

Introduction

This project is a relatively complex one. We recommend you to tackle this one after you’ve gained some decent experience with CNC milling.

As the parts are relatively wide and thin for this project, a good clamping is very important!  We recommend using at least 1 clamp (or screw) every 10 cm to reduce the vibrations and enhance the quality of your surface finish.

The caddy is made out of 5 pieces of solid wood.

Tip:

If you feel comfortable with Fusion360, you can modify the project to host more bottles or even engrave a logo on the sides.

Material

The caddy is made out of 5 pieces but 2 are identical. We thus have 4 Gcodes. 

  • Vertical holder needs a 150 x 310 x 20 mm stock. You need this piece twice for this project.

  • Middle holder needs a 150 x 270 x 20 mm stock.

  • Bottom holder needs a 150 x 270 x 20 mm stock.

  • Handle needs a 270 x 40 x 20 mm stock.

We used beech wood for our stand, but you can use any material you want for this project. Please keep in mind that the project is made for 20 mm thick material and that all the parts fit into each other using mortises and tenons. If you decide to use another thickness of material, you’ll have to modify the fusion 360 project by redrawing all the mortises.


Trick:

Oversize your stock (+20mm at each side) to be able to secure it properly to the spoiler board. Securing it firmly to your spoiler board will not only avoid your piece to fly around, but will also reduce the amount of vibration during milling and by means improve the surface finish. Go check our “Feeds and Speeds explained” article to learn more about the influence of parameters on your milling results.



End mill

We used a 6mm 3-flutes flat end mill for milling our pieces. You can buy those directly on our webshop.

Milling

Vertical Holder

This piece is made out of 3 operations and has to be milled twice to make this project: 

  • With the 6 mm end mill, we mill the mortises for the handle. The spindle should run between 20 000 and 25 000 rpm as the feedrate is 2400 mm/min  with 2 mm passes.

  • Next we mill the other mortises (used for joining the middle and bottom holder). The spindle should run between 20 000 and 25 000 rpm as the feedrate is 2400 mm/min with 2 mm passes.

  • To free the piece we make a contour operation leaving a 0.3 mm axial stock-to-leave you will have to cut using a chisel or a sharp knife. The spindle should run between 20 000 and 25 000 rpm as the feedrate is 2400 mm/min  with 3 mm passes.

Middle Holder

This piece is made out of 2 operations: 

  • To make the inside holes we use a contour operation leaving a 0.3 mm axial stock-to-leave you will have to cut using a chisel or a sharp knife. The spindle should run between 20 000 and 25 000 rpm as the feedrate is 2400 mm/min with 2 mm passes.

Tip:

When making a large hole into a piece you could also use a pocket operation. As the pocket operation will remove all the material inside the hole, this is slow and will unnecessarily use your mill. Making a 2D contour with an axial stock-to-leave is a fast, yet safe way to achieve the same result.


  • To free the piece we make a contour operation leaving a 0.3 mm axial stock-to-leave you will have to cut using a chisel or a sharp knife. The spindle should run between 20 000 and 25 000 rpm as the feedrate is 2400 mm/min with 2 mm passes.

Bottom holder

This piece is made out of 2 operations: 

  • We start by milling the pocket for the bottles.the spindle should run between 20 000 and 25 000 rpm as the feedrate is 2400 mm/min with 2 mm passes.

  • To free the piece we make a contour operation leaving a 0.3 mm axial stock-to-leave you will have to cut using a chisel or a sharp knife. The spindle should run between 20 000 and 25 000 rpm as the feedrate is 2400 mm/min with 2 mm passes.

Handle

The handle is made out of 1 simple contour operation leaving a 0.3 mm axial stock-to-leave you will have to cut with a chisel or a sharp knife. The spindle should run between 20 000 and 25 000 rpm as the feedrate is 2400 mm/min  with 2 mm passes.
