After very long time, yesterday I returned back to my workshop for making my two new puzzle design. This puzzle has six pieces. The aim of this puzzle is making a 7×7 square. Puzzle pieces are here,
Making this puzzle is easy. Because all parts has only two different width. You can set your table saw two time and cut 2a and 3a wooden strips. After you can cut all parts from this two strips. I cut all pieces with my hand miter saw. Puzzle pieces are small and cutting them with power tools is dangerous if you haven’t special fixtures. I made this two puzzle (with big wafers) in 4 hours. Material thickness isn’t critical. I used 8 mm thick wood. For my puzzles each square dimension is 15 mm. Choosing thickness approximately as half of square dimension make looks better this puzzle. I used mahogany. Looks like chocolate. I like making saw traces on puzzle pieces. I make nearly saw traces to all my puzzle pieces. I make saw traces with my hand miter saw. I set cutting depth to 1 mm. You can make also with a small hand saw. Making saw traces take time. But puzzle pieces with saw traces looks nice. I make also chamfer to all edges with a sanding block. For this puzzle you can make also saw traces only upper side of each piece.
I prefer mostly oil finish. A lot of people prefer varnish or lacquer. You can find comparisons for different finish methods on woodworker web sites. An easy to solve puzzle but in same time very easy to make.
