I completed an upholstery course about 10 years ago and have done about 3 projects for myself. I have bought 3 electric staplers but none of them has enough power. I would be interested in buying an air compressor so that I can buy a stapler to go with it. But I don't know anything about compressors. How strong should it be for personal upholstery projects? What's the difference beteween electric compressors and oil driven compressors? Anybody know anything about compressors?
