I left you with this
All the pattern pieces neatly laid out. Now to get them glued down to make a board. The first thing I did was make a black and white outline print of the design. Taped it to my cutting mat and taped some clear library film (sticky side up) over the print. This allows me to build up a fixed pattern which can be glued to a board in one go. Here’s a couple of shots of the progress
outer and some of the next ring (Yew) pieces stuck down to the film from the original layout
inverting the pieces as I went. This is fine for all the pieces. The only thing is the central, Ebony, piece should be four quadrants, not one whole circle. Simple to correct. I drilled a hole in a piece of MDF to accommodate the circular die, tightly. A smaller hole drilled on the rear to allow for the finished item to be released from this jig. With this in place I set the table saw to saw through the middle of the circle (2 mm wide blade) almost all the way through.
and here’s the result
Its a simple matter to use a screwdriver blade to rotate the die by 90° for the second cut
With that done you just saw through the jig again.
Then push the piece out using the hole on the reverse of the jig giving this.
These four quadrants are kept together like this for easier placing in the pattern, again inverted.
After gluing this completed pattern to the 3 mm Birch ply base board (using a veneer press) this is the result.
This is the resin and dye I’ll be using for the ‘grout’
Now the trepidation sets in. This is a pretty little board and I’d hate to ruin it because I hadn’t got the grouting technique off pat. I will be experimenting with the technique. So I’ve dug out the box containing some of the spare pattern pieces from ‘Octagons Don’t Tessellate’ and ‘Are We Having Fun Yet’
I’ll be making some test patterns, some possible examples are
Again I’ll be gluing these to 3 mm Birch ply (I won’t bore you with that bit) and in the next blog I’ll be experimenting with the ‘grout’.
Be seeing you.
