Forefinger is feeling better, thanks!
Here's the pair as they first came out of the electrolytic bath this morning. The one on the bottom in both pictures is the original one, so it has now had both ends done.
Here they are after rinsing and light once over with the broom and wire brush. More shiny areas are still showing up.
This is what is left of the brownie pan. I see why they recommend using rebar.
I put both back into the solution. This time I'm using a brake disc from a Jeep I used to have instead of the brownie pan. (I knew old Jeep parts could be worth something someday.) Another thing I'm going to do is keep the charger amperage on 50 instead of switching down to 10 and 2. This should speed up the process.
I'm not yet satisfied with the results. I did some more searching on the forum for electrolysis and obtained some more links in another thread. Rust removal by electrolysis Rust removal by electrolysis on a trailer frame
I originally used baking soda, two one pound boxes. One internet thread said this works because the baking soda (sodium bicarbonate) is chemically changed to sodium carbonate during the process. Baking soda can be altered to become sodium Carbonate by baking in it in the oven at 300 or so degrees for an hour. The alternative is to buy Arm& Hammer washing soda or Laundry Soda or Sodium carbonate at a pool supply place. I'm going to pick some up today, drain the tank and refill with fresh water and soda. The waste water is non-toxic and the high iron content is beneficial to certain plants. So I will be watering any of those that I might have in the yard.
I hope the changes give me faster results. By all accounts that I've read, it should work fine.

My chemical reaction isn't anywhere near as dramatic as what I have seen in the forum links.
. I can be 
ing on something else while electrolysis is working on rust. You are correct about blasting being messy. Those media particles seem to find their way into places you don't want them and show up later on when you don't want them to. Blasting is also tough on the compressor unless you have a high volume, 100% duty one. Media is expensive (even at the outlet at our coal fired electric plant in town) and the blasting removes good metal along with the bad which weakens the metal, especially if you are doing sheet metal. You have to wear a hood with a shield that fogs up and should wear a respirator with proper clothing to avoid injury, black lung and COPD. It can be tough on your boots as well. It also doesn't work well on the inside of tubing, frames and other parts with blind areas.
