Why do you have two pieces of metal attached to the positive lead? To my understanding only one is necessary, I have even seen people using stainless steel stock pots and the positive lead is just connected to the top edge of the pot and they just hang the part to be derusted from a wooden dowel or piece of plastic

If de rusting a chain , a chain to hold a gas tank not a bike chain . does the cathode ( neg terminal ) need to make contact with every link in the chain ? Also where the neg terminal makes contact with the part being de rusted , can it just be connected to the rusty part , or do you have to make connect with the base metal on part being cleaned ?

I buy, restore, and sell antique hand tools, often badly rusted. Electrolysis is my "go-to" method for rust removal. Your video is the most complete and accurate I've ever watched. I once took a vise that was rusted into an almost unrecognizable ball of rust, and after three weeks and lots of cleaning of anodes, I pulled out the vise. It was down to bare metal and all the previously rusted-together parts of the vise moved freely. It can take a while, but the setup takes only 30 minutes. I do have just a few comments. 1) The anode (the junk iron piece) is not "sacrificial" because the base metal of the anode is not corroded by the electrolyte; however, it does build up with the iron oxides that are removed from the tool you're restoring. For that reason, cleaning the anode frequently is a big help. Nothing fancy, and I don't even remove the anode from the tank. I just unplug the charger and reach into the rusty water with a wire brush and scrape down the accessible parts of the anode. The bubbles will pick up greatly after doing this. If you're OCD, you can remove the anode and really clean it with wire wheels, etc., but that's overkill. 2) Proximity between the anode and cathode is important. The closer they are to each other, the more effective the process will be--just be sure to not short any part of the anode and cathode together. Multiple anodes, as you have set up, help the process. 3) Similarly, I give a quick wipe down of the tool being restored; I do this by reaching right into the tank with a wire brush. This ensures continued good conductivity through the electrolyte. 4) NEVER use stainless steel anodes. They will add hexavalent chromium to your solution and make it extremely carcinogenic. Watch the movie _Erin Brockovich_, in which she is fighting exposure of workers to that deadly chemical. 5) I can't recall the exact chemistry involved, but I've read that the zinc that coats galvanized steel can also produce toxic chemicals in your electrolyte. 6) As noted in this excellent video, the process is line of sight, so it would not work very well at all on, for example, rust on the inside of a steel pipe. However, when I've had hollow spots on a tool that I really want to clean, I will run a piece of steel connected to the anode all the way into (or through) the hollow, being VERY careful not to ground the anode and the cathode. It requires careful placement, but I've seen it done to clean out the rusty insides of the cylinders on a car engine block, so it can be done and it works. 7) As noted in this very complete video, yes, hydrogen and oxygen are produced in tiny bubbles. RUclips videos make much of this as a great danger, which it is NOT. Unless you are deliberately enclosing your entire apparatus in an airtight container and then set a match to it, yes, it would explode, but left out in the shop those bubbles of hydrogen and oxygen just dissipate almost immediately into the atmosphere. 8) I've seen videos of people using vinegar, salt, and even muriatic acid as an electrolyte. These are corrosive to the base metal on your part, which means they'll remove the rust then keep right on eating the "healthy" portion of you're part. Those chemicals are more expensive than cheap washing soda, and they leave you with several gallons of electrolyte that may be toxic and should not be dumped in your yard or down your drain. 9) Evaporust works very well, I'm told, but it's about fifty times as expensive as washing soda, does no better than electrolysis, and, again, you're left with a toxic mess to dispose of. 10) Finally, I go slow, with no more than 2-4 amps and about 15V of DC power. You can use the battery charger if you like, but I have an innate distrust of rushing delicate processes that depend on various chemicals and metals reacting with each other.

How much is it sir?

Here's a myth that Terry doesnt discuss. If you are using 12 guage wires you need flat iron or rebar. Totally false. If you use any anode larger than the charge wire (in this case 12 guage) it is a total waste of resources. You would get the same results with a 12 gauge annode. Try it if you dont believe it.

Very good teaching video you all did a great job

Great explanation and instruction on how to set up. I would use the washing soda for this job like I use washing powder in the washing machine and use enough only to do the job or the powder will spend more time fighting against itself than doing the job it should and as you say it is only wasting powder. I use a small amount of washing powder in my machine about 1/3 cup of washing powder and it also helps the lasting of the washing machine

Great program! How does a person dispose of the waste water? Can I pour it on the ground?

Hello, Terry good afternoon from Auckland, New Zealand ...would like to come over and use ya electrolysis but I'm at the bottom of the earth just south of Australia!

What do you coat the finished piece to protect from rust?

Can you take a 12-volt battery and then put a charger behind it and then use it for the electrolysis

Do you realize how much money this will save instead of using a rust remover like like citrus

Great content !

Is there something to remove the black soot thats on the surface after electrolysis treatment? I have it in areas that are hard to reach.

Audio way beyond bad

Can I use circular saw blades for sacrificial anode?

This is all well and good but you DO NOT WANT TO GET WASHING SODA ON YOUR HANDS. its ph is very high and will slowly burn your skin. its simply not good for you. I recommend wearing gloves at the very least. If you get some on you. rinse hands thoroughly in the sink with clean water for at least 5 minutes. It turns your skin into soap basically and is not good for your skin at all. its only safe in very low concentrations (0.1% to 0.2% solution) Don't get the dry powder on your skin either. Baking soda is fine though and only takes a little longer. Very safe compared to washing soda. Just use a little more baking soda to get a more saturated solution. it'll work fine and wont burn your skin.

Noiosissimo...prolisso....

What the heck is japanning

it seems that everybody use objects that are easy how about bolts how would you clean bolts i have a bucket of bolts i would like to clean

I had a saw setter that only set every other tooth down flipped saw over to get other teeth , was slower than Foley Belsaw but did job well . Forgot its name been 45 years

I wonder if I could ask you a question if you're not too busy. I've been trying this electrolysis and it seems to be working great . But I do have one concern. It's hard to get good clean steel around here where I live. So I've been using tin cans Like coffee cans tomato cans but they all have a coating on the inside. When I'm using the tin cans the liquid solution of washing soda and water stays very clean but there is a lot of bubbling action. No rust scum floating on the top of the solution it all goes to the tin cans and builds up there . I cut the tin cans into and hang them in the solution Length wise. My question to you is using tin cans with a coating on the inside is this throwing off any harmful fumes ? The part comes out clean and the tin cans have quite a build-up of rust build up but the solution is very clean. Thanks

Don't those other People in that Room have any Respect for You?! For that matter You must really have low Self-Esteem. Those People all owe You an Apology

Per the comments on hydrogen buildup, yah they put dire warnings on jumping auto systems, but those "heroes" who are saving your life from an explosion have never done the math. Hydrogen gas quickly disperses in the amounts given off from lead batts.Terry keeps it real.

Sir i need foley bandsaw machine how much we buy this bandsaw machine

🪔🔥❤️😂😀👍

Great info, Thanks

wr r u from sir .iam from india

best sir u r great

Very informative. Thank you!

I see some use salt and vinegar, Is that better?

Will the process damage a wood handle?

What happens if you touch the water while it’s on?

Watch at 1.75x speed. Good videos….

Great video! Thank you for sharing! Do you think I can use a dead battery as a bridge to electrolysis from a charger?

the problem with this is hydrogen embrittelment my favourite method is 10% molasses solution for a couple weeks

Can electrolysis be used to remove "millscale" before welding?

Not to put too find a point on it, but a sacrificial anode is a metal that is of a higher electro activity that is used to protect a metal of a lower activity. For example there is a magnesium anode in your aluminum hot water tank to save the aluminum by providing a higher reactive metal. In a purely grammatical sense the angles “sacrifice “ themselves in that they are plated with the iron ions which are released by the electric current breaking down the Fe2O3 which releases the oxygen and then the electric charge attaches it to the angle iron. Electrons flow from the negative electrode to the positive electrode and carry the iron ions with them.

Hello Terry, first at all i would like to thank you! i´ve been searching as crazy the proportions and nobody tells this! best regards from Mexico, Paco.

Kind of put off with the face nappies in the back ground in a science video.? as we know they don't work.

Wonderful demonstration, Sir.

MASK??????????

I have a question. Can you use pool salt as the electrolyte? I'm trying to derust the inside of a small tank off a generator with electrolysis but it has a baffle so I can't get directly into the end compartment. I only have access through the filler at one end. Hoping it will clean the whole tank out

Very good teacher.

I am so happy to see this video to show people what the guild is all about 😊The toy group are amazing and wonderful people,the time and dedication to the children is a blessing. Thank you all for your hard work and the love that goes with each toy ! I am proud to be a member of the Alabama Woodworkers Guild 🥰

Go counter clock wise when doing inlay cuts

May I know Sir, where I can get this retoother with exactly type.

Nice video - not rushed. I especially like how you mistakenly decreased the angle for the second trial and left it in the video. We all make those kinds of mistakes and it's nice to see an expert share in my pain! One suggestion - it's not really necessary to drill the hole and feed the blade for those trial cuts. Trial cuts don't need to be internal. You could just make some rounded teardrop cutouts from the edge and check the angle that way. Might save some time and the added effort of threading the blade. Great job on the demo and thanks!

Memories.Am still interested in buying some Foley Belsaw equipment.i worked for years in a company ,doing tool sharpening .wouldnt mind getting the Foley Belsaw contact
