Buying an air compressor for your woodworking shop can be a fairly expensive investment when you consider piping, regulators, hoses, water traps, wiring and electricians. You will want to buy a compressor that is capable of the tasks you will be using it for but no more than that. Purchasing the wrong air compressor can be a very expensive mistake. My motivation in writing this has been to give you the knowledge you will need to select the right one.
