Watched some videos so thought I’d give it a try. Took about 7 egg shells ,cleaned ,then on the bbq about an hour at 350. Ground them up got about 1/3 of a cup. I’ve added 2/3 cup of white vinegar. Bubbling away.
some say 5 parts vinegar to egg shells. Will add maybe another 1/3. So I’ll be 3:1. I’ll let it sit for a week sealed and see what I get.The mag part is just Epson salts so that should be easy enough.

Forgive me @myke - I haven't watched the videos. How do you know the process actually creates calcium and how do you measure the final product for use?
 
From my notes; I've made this with great success

Code: 
DIY CAL MAG    
Per Gallon    
12.8 tbsp/190mL Cup apple cyder vinegar    
3.5 tbsp Oyster or Egg shell, flowered    
2.4 tsp epsom salt    
Let set for 7 days or until bubbles stop then strain into water. Use 2-5mL a gallon
 
Well egg shells are 90% calcium or there about.once steeped from the videos one tablespoon to one gallon. I can’t remember the ppm. But was something like calcium 120 and Mg at 240 ppm.

So your about 4/1 with vinegar.
 
I save all my eggshells and put them in my garden. I use calcium nitrate and magnesium sulfate for calcium and magnesium for my cannabis plants.

You can do what you did with the eggshells and I have myself in the past. But now I don't have the time to spend making something that I can buy several years worth for under $20

If I understand it right a tablespoon of this makes a gallon of Ca.Cost will be around umm almost nothing.
Pretty happy if this works.

You need to cover it with a paper towel; So that the gasses made during the process can escape. Not sure if it matters either way, but that's how I was told.
