In this video we sand back the veneer keys.
You can carve or chisel back the veneer keys, but you have to be very careful not to chip back the veneer. I find sanding the easiest and quickest way to bring it back to flush.
Then we start on the lid.
I use a router table to get a good fit on the lid. I make every lid individually for each box and keep them together for the rest of the process.
You should always rout the end grain first because it will normally chip out the grain. It doesn’t matter if you chip out the end grain because you come back and rout out the long grain.
