Electrolytic Rust Removal aka Magic
No. It must be dc supply. Ac will pull rust off both rebar and the tool being cleaned
I dont know why this instructable says baking soda isnt acceptable. I've removed rust off several parts using baking soda no problems. I used 2 tbsp per gallon of purified water, and repurposed a laptop charger to provide 19 volts dc at 3.42 amps. Electrodes were 0.090" steel sheets placed around the part. Exposed copper in the solution didnt cause problems, and took about 17 hours to complete. The part was covered with orange gunk that washed right off. The part needed immediate oil as the solution completely degreased it.
Can i use 16 volts ac supply
Have you tried adding weight to the light end?Or try moving the pick points closer to the centroid.
Bicycle Hoist or "How to get the wife's bike out of my way"
spread baking soda (powdery and clumps) onto a cookie sheet inta a faily thin layer and bake it in the oven for about and hour and a half at 400 degrees.....stir/redistribute every half hour. that easy.... basically the heat allows the hydrogen molecule to combine with ambient oxygen and escape as steam (water vapor), its carbonate ion is released and evaporates as well and the soduim double pairs for a stronger pair to the carbonate beside it.the result is washing soda (grainy like salt)
We do not have washing soda locally, what is the alternate?
I'm going about it both ways I have 3 cast iron pans I found not bad rust but I tried the lye method and it sucked so I have one in vinegar and one electrolysis
Have you tried TC-11 instead of T-9? see test TC-11v.s. T-9, wd-40 , triflow http://www.tc-11.biz/karma/wp-content/uploads/TC-11-versus-WD-40-Tri-Flow-Boeshield-T-9-July-2006-Test-Program1.pdf
My local Walmart does not carry it, I have yet to find a store in our small city that does. I can buy it from our local pool supply company dirt cheap but I have to buy a 50 lb sac. I opted for the "make Baking soda into washing soda" Sodium bicorbonaet to sodium carbonate method. Works fine.
You can use some automatic (smart) chargers, as you said, they might not start because they have a battery/charge detection, but you can kick start them by connecting a 1.5v battery to its leads for 1-2 seconds with some wire. After that charger kicks in and remains on. You can also reconnect without battery later on, I am guessing that solution/metal ions hold a residual charge if it ran for a little while. Just in case someone runs into the same problem.
Great article and very well design setup!Instead of a car charger you could use an old PC Power supply. You can use the 12v rails.They offer plenty of amperage plus OVP and OCP even if they are cheap.Thats what i will be using anyway!Cheers!
