This cheap airbrush comrpessor works well for my needs but it has no tank so it kicks in all the time and can't really keep pressure when spraying for more than a couple seconds.
To fix this problem and make this tool more flexible I make a 2.4l tank out of scraps and recycled materials. All in all I spent less than 5€ for the "T" connector and the 5 10mm tubing to 1/4inch pipe thread so this was pretty much free to make for me.
Of course there are many other ways to make something like this, as I mentioned you can buy all the connector you need for cheap at home improvement store in any size and shape, I made my own just to play and mess around! The tank as well can be made of other things like an empty fire extinguisher or other kind of pressure safe bottles.
The tank pressurized at 60psi will provide air to airbrush at costant pressure for as long as needed without dropping below 15psi. It can also be filled up and brought outside for a quick spraying if you don't have a dedicated airbrush station and just want to basecoat a model.

Index of operation and materials:
0:30 Tank needs to go before the pressure regulator so it fills up to high pressure (like 4bar or 60psi) therefore storing more air.
0:46 Propane-butane gas torch bottles
1:10 Drill out safety valve
1:40 10mm tubing
1:60 All threads must be sealed with teflon tape
3:30 Spraying time already improved by a lot!
3:50 Going with 4 bottles of 600ml each
4:30 Drill holes on this scrap aluminum round stock to make the 5way connector
5:26 18mm holes tapped with 1/4 pipe thread. Smaller fittings would have worked just as well and are also easier to drill and tap but this is the size I have on hands (got this tap at a flea market, these things are expensive to buy new)
5:50 10mm tubing to 1/4inch male pipe thread
6:05 Cage for bottles made with scrap wood and plywood
6:42 Compressor screwed to plywood base through rubber dampening feet
7:00 Now spraying time is great at 15psi, way more than I will ever need for a single spraying so it stays at the same pressure all the time.

Thanks a lot for watching, I hope you liked the video!
