Going into the day job early evening today, so I had a few minutes to rub together in the shop and the tool box lid needed some love. I had time to cut rebates or at least the X-grain ones. The Panel is Cherry, ended up about15mm thick and needing a 9mm thick tongue set back 10mm. While I have the LV rabbet plane, for a single panel like this a wood rebate plane works just as well and is less monkey motion.
I use marking gauges to make two marks, one for the set back and the other for the depth. For a long rebate like this one I will chisel a "V" groove. Then it is just a matter of riding the groove until you have a shoulder, as my clients would say "A sheet of cake".
First photo is of setting up:
About half way through:
Testing the fit:
Two more rebates, draw bore the rails and stiles and the lid is finished.
