After the Veterans parade (I am a vet) I went looking for a compressor. Looked at HomeDepot, Lowe's and ended up at Harbor Freight. It is only 21 gallons but it was in the right price range. Hopefully it will work out and have sufficient volume. I need to build some kind of sound barrier because it is very loud in the hanger. I saw plans for one on someone's web site, but I did not bookmark it. I hate it when I forget to bookmark something. Back to searching other websites. When I get one built I will post the plans here for someone else with the same problem.
