I managed 5 mins in the workshop and after 3 hours...
More of a test and familiarisation exercise on the use of the Kapex than a serious project. I initially tried using stop blocks to cut to length but this was not accurate enough for some reason so I taped the pieces together and cut them all at the same time. No fettling required joints are as tight as a gnats rear end.
I have used surface splines before on a square trivet years ago so did the same here. Lignum vitae used for the splines. Scrap pine for the rest.
No finish it will go straight in the kitchen.
When I get time a will make a nesting set of 3.
