Thanks to everyone who helped with guiding me through my first dip. http://k2forums.com/discussion/9396/dipping-a-stock-vertical
Since then I have had many requests from people to do work for them, including a gun shop. This got me researching and now I have opened a small on the side business, currently I am doing my first job.
I thought I would share some pics my simple cheap setup to help give others ideas.
My tank is made from an IBC container and a 200L chemical drum. I have lined the edge, made dams, overflow and filter with S/S sheet.
The pump is 8s a submersible 15,000L P/H with float switch, plumbed with Pvc through 2 bulkheads into the main tank, then runs through a check valve and upto a pvc spray bar in the centre to equalize yhenjet power. At the outside of spray bar there is 2 ball valves down low to adjust power and increase deep circulation.
