Electrolytic Rust Removal aka Magic

Step 8: Samples

Here are a few samples:

The chisel was very rusted – normal rust removal would have required much original steel grinding to remove the deep pits that a wire brush would not have touched. Check out the stamp that was revealed after cleaning.

The entire project was started because I bought this sweet plane that was totally rusted. I only paid a few bucks, but knew that a used non-rusted one was worth quite a chunk of change. After the tank proces it took about an hour of going over it with the light wire brush wheel on the dremel to shine it up – but it would have been impossible without the electrolysis first.

Hello, I'm currently doing this in the back yard, loosely based on your instructable. What I'm noticing is, with tools with uneven rust coverage, that the areas with the least rust seem to attract most of the electrolysis, leaving the most heavily rusted areas untouched. Have you noticed this? Is there a way to counteract it?

Great job! That stamp is interesting... it looks like it says "nsted, CONN, USA". I live in Winsted, CONN, USA... humm....

Thanks! I also wondered abut that stamp. Tthe plane was made in New Haven.... Ive been buying these tools in CT so im guessing many of the old timers bought local stuff...

is it an old Sargent plane from Sargents in new Haven? lol Im from Hamden Ct. and Sargents (in the 1980s) was a good customer of ours, t that time they just made locks.

Well done, the plane looks very nice after refinishing. Yet an other example of trash to treasure. I've got a lot of old "rust-balls" sitting around my shop. Maybe a little time under water is just what they need.
Thanks for the info.

Just for reference, I successfully, used my old granite polishing pads to polish the table top of my cabinet saw. This resulted in a near mirror like finish, which is even better than the original factory finish.

These pads work on angle grinders.  Preferably, the grinder would be a variable speed model.

The [diamond] grit range is 50 to 3000 grit (plus buff grades). I used the 400, 800, 1500 and 3000 grit pads, just as you would move to progressively finer grades of sand paper, when sanding wood and such.

You can extend the life of the pads using oil to lubricate and cool. Normally, you'd use water, but water and woodworking equipment just doesn't seem to go together well.

Do you think that this will also remove paint?

yes, it almost certainly will - depending on the type of length of time under the treatment.

An outstanding bit of procedure!!! I'm anxious to try it.
