1 PASSIONATE ABOUT CNC Project Tutorial For more FREE projects visit - Compatible with Current Version of: and The Chubby Box Designed for Vectric by Michael Tyler Sample Carved with: ShopBot Buddy PRSalpha BT48 The Chubby Box features precision pockets to fit lengths of dowels that form the convex sides of the box. The files were created with the Vectric VCarve Pro software which made laying out a project like this very easy to do. The box lid features a design created using the Fluting Toolpath and a V-Bit, as well as chamfered edges using a Profile On toolpath using the same bit. The project sample has a twotone stained finish, but you could use contrasting woods to achieve a two-toned appearance instead of using stain, if you wish. Main items you will need: 1) The Project Files (included): Chubby_Box_Layout.crv 2) Boards with the following dimensions: Chubby Box: 0.75 " x 7 " x 24 " Box Bottom*: 0.5 " x 4 " x 7.5 " * (cut bottom panel with your table saw) 3) Eighteen 7.5 " l engths of " (7/16 ") diameter dowels. Three 4 foot dowels will be enough to cut the lengths. 1" diameter round wooden ball knob (for lid handle) 4) Wood glue, clamps, sandpaper, wood stain and/or paint and clear finish 5) A Dremel-type rotary tool with assorted sanding wheels and bits to sand small details and speed up preparation for finishing. The finished project is about 8.5 " Wide x 7 " Deep x 4.5 " Tall CNC Bits used for the Sample: 90 V-Bit 0.25 " Down-Cut End Mill (EM) Designed by Michael Tyler - May 2017 VCP-85

2 STEP 1 - Open and Review the Project Files Start your VCarve or Aspire software and open the project file(s). (fig. 1) Chubby Box Your board will look something like this. (fig. 2b) fig. 2b Chubby_Box_Layout.crv STEP 3 - Separate Part(s) from Material and Sand Separate the parts from the board with a utility knife or hobby saw. Sand off the tabs, fuzzies and any undesirable toolmarks. (fig. 3a, 3b) fig. 1 Chubby_Box_Layout.crv Carefully review all the toolpaths and make any necessary changes to suit your particular bits and machine. The toolpaths are currently set with feeds, speeds and pass depths that were used in creating the original sample. Please don t use them directly until you review them for your own setup. Separate parts from the board fig. 3a You can edit the tools and change the settings to your own preferences and requirements. It is very important to recalculate all toolpaths after making any edits/changes. Once you have recalculated for your own machine and bits, reset the preview, then preview all toolpaths again to visually verify the project outcome on-screen. STEP 2 - Run the Project When you are satisfied with your settings, save the toolpaths to the appropriate Post Processor for your machine. Place your material on your machine bed and proceed to run the file. (fig. 2a) STEP 4 - Cut Box Bottom Panel and Dowels Use your table saw to cut the box bottom from 0.5 " stock. The dimensions are 0.5 " x 4 " x 7.5 " (fig. 4a) Cut the box bottom using your table saw Sand off tabs, fuzzies and toolmarks fig. 3b Page 2 fig. 2a fig. 4a (cont.)

3 STEP 4 - Cut Box Bottom Panel and Dowels (cont.) Cut " l engths from the " diameter dowels. I used my band saw with a stop block to assure each dowel was exactly the same 7.5 " length. (fig.4b) Chubby Box STEP 6 - Assembly Apply a thin layer of glue into the pockets and insert the dowels and bottom as you did during the test fit. Clamp until dry. Drill a hole in the lid center about 0. 5 " deep. Insert and glue a small dowel into the lid and knob. (fig. 6a, 6b) Cut 18 dowels to a length of 7.5 " Glue the box parts together fig. 4b fig. 6a STEP 5 - Test Fit and Apply Stain for Two-Tone Look Dry fit the dowels and bottom into the pockets of both ends. Make any adjustments (sanding), if necessary. I didn t need to, but dowel diameters can vary, so it s best to do a test fit to be sure everything goes together well. (fig. 5a) Test-fit the parts to confirm everything goes together well fig. 5a Glue the knob to the lid fig. 6b STEP 7 - Apply Final Finish Apply the finish of your choice. Since I stained the parts before assembly, all I had to do was apply several light coats of Krylon Acrylic Clear overall. (fig. 7) Take everything apart and apply stain if you would like to do a two-tone finish like the sample. I stained both end panels and the wooden lid knob. When the stain was dry, I applied a couple very light coats of clear Krylon spray. I did not stain inside the dowel nor the bottom pockets. (fig. 5b) Applied Krylon Acrylic Clear Spray Page 3 I applied Rust-Oleum Golden Mahogany stain to the ends and the lid knob. Then applied a couple light coats of Krylon Clear. fig. 5b In Conclusion Apply self-stick cork underneath the box to protect surfaces. I hope you enjoyed making your Chubby Box! Happy Carving!
