This playing card box was made from a floor joist salvaged from a 150 year old house that was in the process of being renovated. While working on this project, another TechShop member identified this piece as Spruce, and from the small amount of discoloration caused by Spalting, it was most likely cut from a tree that was dead for some time.
That means this project may actually be the second time this piece of wood was reclaimed!
Tools (available at TechShop):
ShopBot with 1/4" spiral bit
CAD software (Autodesk Inventor)
Table router with 3/4" round over bit
Step 1: CAD Design
Prior to creating the CAD design, the lumber was run through the planer (sorry no photos) just enough to remove the rough sawn sides. Afterwards, the thickness was measured, and fed into the CAD design.
The final design was read into the VCarve software to program the cutter paths and output the tool path file for the next step.
Step 2: CNC carve the shape
The two halves were cut on the ShopBot using a 1/4" spiral bit. This made the machine time a little longer than using a larger diameter router bit, but it allowed us to make deep cuts, and complete the job with a single bit.
