After a lot of measuring, drawing, thinking and picking out pieces of wood the test build of a first full pad has finally started!
Access to an original pad meant it was easiest to just copy all the sizes from here. The tiles being the most important to get right.
Tomorrow the rest of the parts will arrive and it is possible to try and get this one pad working and pretty looking. When the pad is complete and everything fits and works the newly compiled knowledge can be applied to the making of the second pad.
