Ok, at
@rmorris_14 suggestion of lots of horrible pictures, I decided to go ahead and make another Aragocrete Rack for up to 3 Bowers or 3 of my Blastos or whatever I decide - maybe Favia or something? Ok, enough delay - pictures and instructions!
I started with a piece of egg crate lighting diffuser and cut a piece big enough to hold what I want:
Then, using a heat gun I heated the egg crate at the points I wanted to bend and bent the legs at a 90⁰ angle (don't over heat the egg crate or it will warp, don't under heat it or it will crack while bending):
Next, I added a base of moist aragonite sand (not soaking wet, not dry - just enough to stick together) to the curing container so that it will touch the base of the rack, placed the rack in the sand and filled in around the edges for where I want the Aragocrete to be and add the dowels:
Next I clean the old, dry Aragocrete out of the mixing bucket (set aside for later projects!), added about a cup each of Portland cement and aragonite sand and mixed well:
After mixing well I add water a little at a time - you want the consistency to be chunky but stuck together good - not enough water and it'll be crumbly, too much and you'll have pudding with no texture on the rack. I then add some water softener salt (smaller pieces make smaller "craters", bigger pieces bigger "craters") and mix thoroughly, then coat the exposed egg crate:
Now, the work is basically done so I remove the dowels and cover the rack with moist aragonite sand fully at least an inch over the top, replace the lid on the curing container, and wait 24-48 hours for it to dry enough to handle (this picture is VERY important):
Usually, after 24 hours I'll go ahead and pull the finished project out to air dry for a couple of days before putting it in a bucket of water to start the leaching process.
Even if this was TLDR, at least it had some pretty (ugly) pictures!
