I am looking at building a swirl filter out of a 55 gallon drum. It will be outside of my fish room due to space limitations and i would like to keep the smell outside.
I have seen swirlfilters made out of drums on the internet but think they would be hard to clean due to the flat bottom. So my thoughts are to put a cone bottom on one.
I have access to 125# steam pressure. that i could use to heat the drum up and reshape it, but i can see this method getting away from me and ruining the barrel. So this is where i would like your help.
How can i cone the bottom of a 55 gallon drum, make it completely leakproof, and not spend a ton of cash?
I got it from FDS in Botkins Ohio.
