Started this project in early Jan when i saw them by degoose.
Made this drawing immediately to see if I could figure the angles.
60 degrees () to make 6 sided figure was the clue. 360/6 = 60. Took me awhile and drawing the box in bottom right of this drawing.
Next hurdle was how much wood of each type (color)? In The drawing top middle, shows board 1.6” thick. Cut on 60 with all sides equal to hypotenuse. in this cause sine 60 = 1.6/x or x= 1.85”. all sides need to be 1.85” in length. set saw at 60 cut end off at 60 and move fence 1.85” + kerf(K).
Also need length of boards to decide how much of 7” cherry, 7” wide walnut and 7” maple.
From drawing I counted 32 octagon pieces. I can get 3 cuts from 7” so I need 12 pieces from each board. 12 pieces times 3 is 36. I have 4 left over. I may need them. 12 pieces from each board and each piece is 1.25 ” thick for final board plus K. 12×1.25+K= 15+K = 15+12/8ths = 16.5 inches long. I treat this as minimum length and cut more.
I cut and planed a piece of cherry, maple and walnut 17” x 7” x 1.6”. And then cut them at 60*. I use a block of wood to set fence then spacers and feller gauge to move fence closer for next cut. Should have show the set up. It is exact to get the fence moved accurately.
All that is left is gluing up sets:
cutting 32 pieces off:
and gluing and sanding and finishing.
Gluing up was a learning. Thought I could simple stack them in square corner and glue whole board at once. THAT DID NOT work.
Ended up gluing up a row at a time with pretty good success. Wish I had taken more time and fit each piece, but by the time I ended the gaps were getting bigger. I don’t know if it was accumulating error or last stack was off from glue up.
At any rate here is sanded result:
I’ll be back
