Coming soon. Full "How To" info and pics of The Rust Buster!
OK here is "the unit"
Here's what it looks like in the hole when it's eating rust
This thing is killer!
How it works....See the four pieces of bed frame angle iron hanging into the plastic barrel(Barrel MUST be plastic so it can't conduct electricity!!!)? They are welded to a ring that just fits inside the barrel about 6" off the bottom
You'll also notice at the top just outside the top...there is a piece of wire that runs around and is connected to the angle iron. Shine it up first and run bolts into holes...bare a strip of the copper wire, wrap it around and bolt it down tight.
Bare and twist the ends of the wire together.
You've now created the Positive electrode. The part that hangs into the solution will disappear over time so don't bother makin it too pretty.
Next pour about 12 to 15 gallons of clean water in the barrel. Lay a 2X4 or 2X2 across the top.
Take your part you want to derust...grind a clean spot on it near a hole or whatever. Clamp or bolt a sanded or wire brushed piece of steel coathanger or tie wire to the piece. Hang it into the water so it is covered and roughly in the middle of the diameter of the barrel. DON'T let it touch the electrode steel inside!!!! This will short out your power supply.
Now scoop in two heaping table spoons of Arm and Hammer Washing Soda for every gallon of water. You may as well throw in a couple of handfulls of extra...but not much more.
The strength of the solution dictates the current draw. Too much washing soda and the amp draw may be too high.
Next...Take a battery charger...6-12 volt is best but straight 12V will work. Make sure is sitting in a safe place and won't catch anything on fire if there is a problem.
**** Do this outside...The process produces hydrogen gas that can explode****
Put the negative cable on the wire that is hanging down into the solution with the part tied onto it.
Next hook the positive cable onto the wire that circles the outer electrode end. The ends that you twisted together is best.
Plug in your charger...turn it on and watch the amp draw. Best seems to be around 4 amp draw for a 24 hour bath.
If the draw is too low you can add more washing soda till the amperage rises to where you want it. If the amp draw is too high...add water or move the part away from the electrode.
When it starts to fizz you'll know you have good connections. It will soon look like it does in the pics.
24 hours in the tank seems to be a good target time.
After it's done...put on rubber gloves...yes...this shit is corrosive and will burn your skin. I know !
Wash the parts off in a container of clean water. Use a ScotchBrite pad or a BBQ brass brush...I like that the best.
Oh yes...all the usual...don't let your charger get wet...keep kids and critters from drinking the solution...don't let the kids throw their sister in the vat etc.
The first pic is a set of Ford spring plates that where really badly rusted. I was actually going to chuck them...glad I never.
Next is a couple of plates...one badly rusted and the other is rusted and greasy. You should knock off the bigger chuncks of grease so it won't oil down your solution.
Note..the more rust a part has the blacker it comes out. Scrubbing under water with the brass brush works well.
Part should be painted or oiled as it may rust fairly quickly.
Any questions...feel free to ask!
