What im looking to do is set up a small fill station in my basement. What i imagine is a large tank ( something the size of maybe two SCUBA tanks ) attached to maybe a "Shoe Box" compressor. My question is, will this work? The reason i want to do this obviously is for quick fills rather than waiting for the Shoe Box compressor to fill one 68 tank in 3 to 4 hrs. So the Shoe Box would keep the PSI of the larger tank maintained over time while i fill smaller ones off it.

Any feedback would be helpful.
