Introduction: The Purple Heart Shaped Box

Today I'm going to show you how I made my wife a Purple Heart Shaped Box for Valentine's day.

Step 1: Pick Your Wood.

My first step was to go to my local lumber yard and pick up a big chunk of 28" x 9 1/2" x 7/4 purple heart for a little under $22.00.

Step 2: Cut a Piece to Size

I then cut 7 1/2" off the end by making 2 shallow passes. 1 on each side of the board.

Step 3: Resaw Into 2 Pieces

My table saw isn't very strong so I set my fence to 1 1/8" and ran a shallow cut on one side and then on the opposite side. I raised the blade up a little bit at a time, cut each side, repeated the process, and eventually cut through the whole piece.

This left me with one board at 1 1/8" thick for the base and one at 1/2" thick for the lid.

Step 4: Program the Heart Shape Into Your CNC Software

I have an X-Carve CNC machine so my next step was to design a box using the free Easel software on the Inventables website. They had a heart shape already in the software so I made the lid by nesting 3 hearts on top of each and the base by nesting 4. The lid is on the right and the base is on the left. The center heart of the lid is set to 0.025" to level out the wood. The white part around it is set to 0.125" (1/8") to create the lip. The black outline is set to 1/2" to cut the outline of the heart.

The base on the left is cut similar except that center is cut down to 0.850" for the tray. The other hearts are there to level the lip and cut the outside of the heart.

Step 5: Mount and Cut Your Lid

Next I secured the 1/2" piece of Purple Heart for the lid to the base of the CNC machine and cut it out. The heart on the left was my first try. My wife came out to the shop to ask me a question and I bumped the CNC machine on my way to talk to her and knocked it out of alignment. The second try cut with no problems.

Step 6: Mount and Cut Your Base

I attached the 1 1/8" piece and cut out the base. When I set up the software to cut the first tray I forgot to change the cut settings from Pine to Hardwood and it cut too fast and too deep and snapped the 1/8" bit that I was using. I was able to cut a larger heart shaped tray the next day and salvage that part of the wood.

Step 7: Finish Cut and Shape Your Pieces

Once I had both pieces CNC'ed I finished cutting them out on the band saw and cleaned up the edges on my disc/strip sander.

Step 8: Sand, Sand, Sand....

I spray glued and stapled a sheet of 100 grit sandpaper to some plywood to be able to sand the bottom of the lid and the top of the base flat to each other.

Step 9: Apply Your Finish

Everything that I read on the internet said to not use a water based finish on Purple Heart so I picked up some Tung Oil and applied 2 coats according to the directions on the can.

Step 10: Add Felt to the Base

Once the finish was cured the final step was to trace out and cut some adhesive backed felt paper and apply it to the inside of the base.

Very well done! I wish my lumberyard had Purpleheart that thick.
