I used a tank I got from a friend who had a good sized unit that had a bad compressor. So I scoffed the tank.
....but before that, I used a 100 lb propane tank , but the problem I had with that was it took a year to get the stink out of it..they use a low LP detector chemical that smells like rotten eggs and it inpregnates the tank.
It did clear up and I did like the tank B/C it was tall and slim, so it takes little floor space..although I hung it between 2 ceiling joice in the Barn. Good fit with 2 straps.
I had to tap a hole for the drain, which was no problem.

I also made one for a constuction friend out of a portable aux air tank and he would use it if they had a few guys on a roof ..it gave them that little extra volume need for more guns..they just plugged it in-line from their portable Emglo unit and then ran a mainfold off the tank...was slick and many of the other guys copied the idea....
