Oakie, I have a retainer ring welded at the bottom of the 12" spool above the thumper to hold a copper screen that scrubbers will sit on. Doing a vinegar run as we speak. Never been around a thumper before. It's cool to hear this thing come online.
Thanks Squatch. I'm kinda proud of it. It's just gurgling along right now. Have to get a sacrificial run fermenting to get an idea how it will go in the real world.
Overhead the albatross
Hangs motionless upon the air
And deep beneath the rolling waves
In labyrinths of coral caves
An echo of a distant time
Comes willowing across the sand
And everything is green and submarine
