Surf board style balance board and roller sections.

the main board is very self explanatory but the 120mm circles need to be glued togeter to form the long roller. I have added a 5mm hole so the user can use a bit of rod or something similar to aid the alignment of the individual circles.

Tabs will need to be added to each piece to ensure nothing becomes loose during cutting. 

5mm compression cutter and 60 degree Vee bit for engraves and profiles. 5mm dowel drill for holes to align the circles.
