Have Ingersoll Rand inline sanders. Several types of Hutchins sanders, and a couple electric angle grinders. Tried many different sanders over the years electric and air but IMHO the Hutchins are by far the best. Well worth the money. Last for years with proper care. Air chisel with several modified bits work great for removing stubborn transom wood. Also have crowbars and wood wedges on hand.
