First I had to prep the wood. Most of this was done with powertools. Cutting a piece of wood from the last cherry plank, planing, resawing it on the table saw, and more planing and thicknessing, They ended up at the 10mm thickness I wanted them to be, It was a squeeze though, the thick tablesaw blade eats up a lot of wood. I really need a bandsaw!
Then I marked out the exact position of all the cutlines. I don't really measure at all, every mark is taken from the other parts, like here, the inside width of the cabinet. This method is much more precise then measuring with a rule.
For the sliding dovetail I first chop a small mortise at the end and mark the sides with a deep knife wall.
And then it's a matter of sawing the sides of the sliding dovetail socket. It';s going to be a half dovetail, so one side is straight, just keep the saw vertical, the other side is at an angle. To give myself an idea about this angle while sawing I set a sliding bevel in front of the board.
The male part is cut likewise. I didn't shoot a picture (sorry), but it is a matter of sawing the baseline and cutting the sloping part with a chisel. Only a little bit of material needs to be removed, so this is quick work.
And here is the result. Not perfect, but not too bad for the first time either.
