I have about 10 saws that I’ve collected over about 5 months. As well as a few planes, and other tools. I was getting tired of sanding the rust off, and wanted to find a way to do a few things at once.
I had a 12v battery charger in my garage, a few tubs to put water in, and some spare steel for the sacrificial anode.
Where I am, the local stores don’t seem to carry “Washing Soda” so I had to find an alternative to Sodium Bicarbonate. I found a product that was Sodium Bicarbonate and something else, it was basically washing soda but a different product.
I filled my tub with water, pugged in my battery charger, and wha-la! It didn’t work.
Turns out my battery charger has a trip feature, that if there is a loop or a short in the circuit it will cut power.
Well, that doesn’t work! Turns out I had an old battery in my garage from a car I no longer own, so I thought, why not charge the battery while taking the charge out of the battery? So I plugged the battery charger in, connected it to the battery, then using jumper cables connected the battery to the anodes in the tub…
After a few hours the water turns a NASTY black, with some foam on the surface.
I left a #78 rebate plane and a saw blade in there for about 10 hours.
And a Jackson Warranted Superior Saw
After it comes out of the Electrolysis bath, a little bit of steel wool to take off the black residue, and some light sanding brings this to a great finish. At the present, I like to keep my saws with a little bit of the patina on them so as to enjoy the fact they are old, rather than make them look like new.
