Cleaning the Brass Nuts and Finishing Up the Blade
Looking at the brass nuts that hold the handle to the saw, I could see there was both a bit of corrosion and tarnish. Kind of hard to see in this picture, but you get the idea. So it's a trip to the grinder that has a buffing wheel charged with tripoli.
The result is a nicely polished nut. I use a rag to hold the nut in a pair of pliers, so the pliers don't damage the nut. Be careful, as the wheel can grab the nut and send it flying if you're not careful.
It's the next day, and time to get the saw out of the electrolysis bath. Here, you can see what's happened to the cookie tin used as a sacrificial anode, as well as the rust in the container that I used. There's a pretty thick layer of it on the bottom (hard to see just how much, but a pretty substantial amount for just one saw) in the picture.
My battery charger is a 10 amp car battery charger. I would really love to have one with a little more torque - its tough to get a large area like a saw, a few more amps wouldn't hurt here.
Here you can see the results in the next stage, where I apply some paste wax to the saw as a rust preventative. The wax will come off fairly quickly on the exposed parts of the saw, but will remain under the handle for years.
The end result isn't going to fool anyone into thinking it's a new blade, but should still work quite well.
