This was so easy. A nice piece of cumaru. An old Singer treadle sewing machine base. Two pieces of 6/4 oak to offset to the proper height. Oak affixed to tabletop with dowels at slightly off right angles. Base attached to oak with 2.5 inch hex topped wood screws.
Corners traced from top of cookie tin. Edges rounded with a router. Finish is the usual – sanded to 220 grit, tung oil and limonene.
Now if only the treadle could be connected to a generator to supply power to the desk. Could be a fitness desk. For the moment though, it serves happily.
