There's a really simple answer to this issue: Buy an ax and hatchet at a garage or estate sale for a few bucks. Chop down some trees on your property and hack out some beams, poles and siding. Pin it together with help from some neighbors or family and stand back to admire your work. Should only take a few months. Besides saving your gold coins, a lard filled body will be replaced by steel, muscle and a few calluses.
