I did a lot of pausing and zooming on Paul’s videos to see if I could work out how he did it…
I put rebates in the front edge and sides of the lid, and also all the way around the drawers. I then (with varying degrees of success at first) ripped some thin stock and put a bullnose on one edge… (ended up producing the thin pieces using a plough plane … the ‘waste’ if you like, became the bit that was needed if you plough from the face and then the edge and meet in the middle)..
Then I glued and panel pinned it on and mitred at the corners. Filled the holes with some matching wax filler after setting the nail heads and planing the beading flush with the adjacent edge.
… On the last episode of the tool chest series / the episode on finishing with shellac… Paul is seen in the opening of the video filling some holes… This was also a clue to his method.
Did the same thing but without the rebates / glue for the book matched lid panels.
Hope that helps .. Probably could have explained better.
