i have a 20 year old Craftsman Air compressor and I fear it is time to replace it. I am building a farm house table and bench for a coworker and came time to sand. I did the bulk of it with a 3x21 HF belt sander but for the finish sanding I am trying to use an orbital air sander but the compressor can’ seem to keep up. It is a 6hp 30 gallon model I bought new in 1999. It has seen minimal use in the 20yrs I’ve had it. I pulled the bottom plug and blew the tank out, made no change. I guess I will buy an electric orbital sander. Any suggestions on what I could do to improve the compressor, I was hoping to use it to paint Willard soon but I fear it won’t handle it since it cannot keep up with the sander.
