Thanks for the advice on the impact sockets - I ordered one off of amazon with 1 day prime shipping! Should be here tomorrow. I do have a dremel and I'll probably try to hack some of the material off until the socket gets here. Even if I can get it with the breaker bar, I'm pretty excited to get an air compressor. It will make a nice addition to a house that I'm in the process of buying. In case anyone is wondering what I went with:
Husky 30 Gal. 175 psi High Performance Quiet Portable Electric Air Compressor-C303H - The Home Depot
Husky 1/2 in. 800 ft. lbs. Impact Wrench-H4480 - The Home Depot
