So this actually gets back to car related stuff. So I've got an OLD compressor. Sits on wheels and the tank is probably 18-22 in diameter and 30-36 wide. So, I am thinking it's 5-8 gallons. I've been wanting a bigger one. If 20 gallons is really insufficient for just some die grinding, what's a decent size that you can probably get a HF that will do some grinding, maybe some painting? What does everyone else have?
I have a 33 gallon and experienced the same thing Mike does. Die grinders, cut off wheels and angle grinders only run a few seconds before compressor comes on. I think you need to get to about a 60 gallon tank with appropriate compressor before you can do a lot of that stuff without continuous running.
