The more volume, the less it will run while you're working. If you have the cash and the storage space get one of those tall IR floor mount models. Don't get an "oil free" compressor, (such as many of the craftsman models) they are xtremely loud. And certainly don't try to use a pancake compressor or any other carpentry type. You need volume (automotive) Get an oiled sump model with an electric motor, belt driven pump.
Below is a link to a satisfactory "best bang for your buck". Been using mine for six months and very impressed. Know a few others using this model too.
Similar units are available from different vendors such as Lowes, Tractor Supply, etc. The big tank and oiled compressor will easily handle any task in the course of building your plane. I bought the Home Depot version when I started painting my RV-6 and wish I had it for the entire project. It has since painted several automotive and aviation projects.
