A 110 volt compressor isn't going to cut it. Better make some provision to get 220V in the shop. I have a 7.5 horse twin stage compressor with an extra 80 gallon air tank in addition to the 80 gallon tank on the compressor and working by myself I can tax it quite hard.... Just study the CFM requirements of the tools you have now, then look ahead to the air tools you want to have and get a compressor a size bigger then your future needs dictate.
As for a grown man having to ask permission to get a bigger compressor------You're kidding, right???? Please tell me you are JFK:HMMM: :HMMM: :HMMM:
