Reset the wedge firmly, tapping it tight with a few gentle mallet strokes while holding the iron tight to the frog. If the blade isnât set square to the sole of the plane, a tap or two to one side or other on the portion of the iron that protrudes above the wedge should align it. Then set the depth as described above.

Citric Acid. An acid solution weakens the bonds that formed between the copper and oxygen atoms to create the copper oxide. Citric acid, contained in lemon juice, is a weak acid that will break those bonds.The experiment can be repeated with other acids, such as vinegar.ait five minutes, then remove the penny from the lemon juice. The penny will get cleaner the longer it sits in the solution. Wipe it with a white paper towel. Any remaining dirty coating, which is actually copper oxide, will rub off as an orange stain on the paper towel, leaving the penny clean and shiny.
