Some years ago I found, perhaps at a garage sale, a small (2 ft. long, 2 ft. high) workbench. It has been useful, but it was really beat up:
Looking closer at the top:
It really had to be replaced.
So I took some plywood and cut it to shape. Two slices of nice Baltic Birch and one of cheap stuff for the middle of the sandwich. I glued them together:
That is a 55 lb. anvil. In addition to its usual functions, it is quite useful as a weight for clamping.
I then sanded the edges of the pieces:
I drilled a row of dog-holes, then screwed it to the legs:
I then stained and finished the top:
I suppose I will screw the vise back onto the new top. It is covered with paint and looks terrible, but works perfectly.
