As you can see, it is a tad rusty, and the sole is covered in what looks like paint.
Once the plane is dismantled I see there are a bunch of parts that need some attention.
video on Woodworkers Guild of America, plus the detailed instructions, Mr. Vondriska does a nice job presenting the process, and has the idea of using a coffee can for the anode. Instructions from Make: Magazine's project's blog by "Stan the Toolfool" and an article from Rick's Woodshop Creations. After reading up on the process I was ready to get started.
Fortunately I have a neighbor who does a lot of car work and was willing to lend me his battery charger (thanks, Jeff), and a neighbor who has laundry soda (thanks Teri). With leftover wire from the electromagnet experiment at the last science birthday party, a 6 gallon bucket, and an old coffee can we had laying around, I had everything I needed.
To make the anode I cut the coffee can in half to make two half cylinders. I drilled 3 holes in each side and re-connected the pieces with wire. I did this to give myself more room for the tools. Since the plan is a No. 5 I had to use the 6 gallon bucket, plus this expanded anode, to make room. That process probably took the longest, as I was using 14ga wire and wearing gloves so I didn't lacerate my hands on sharp can edges. I also put a hole on either half at the top and wired up the leads there.

I first did the blade, half of which was covered in surface rust. I mixed the soda ash in the water, put together all the pieces, and suspended the blade.
As soon as I fired up the charger I started seeing bubbles. I wasn't getting 2 amps of current reading on the charger's ammeter, so I switched it up to the 6 setting.
After a while some sludge accumulated at the top. I left the blade in for a couple hours. I pulled it out a few times to check, it was pretty clear the process was working.
|Sorry about my photography skills. My worktable was now in the shade. The black areas are where the rust was removed.|
