With this Instructable I will be rebuilding a Stanley #220 Block Plane found buried in a box at a flea market. It has all the parts, just some dirt and surface rust from neglect.
The first step it to assess the piece, see what needs replacing and how square it sits. With this one I am in luck; everything is mostly square and in place. So I take it apart and clean off what rust I can, surface dirt and grease.
Step 2: Goo
I am using Naval Jelly to remove the rust on this tool. I brush it on liberally and let it sit for ten minutes.
Here are some warnings to pay attention to:
- Naval Jelly is a water soluble acid (Phosphoric acid). Yes, it is an acid. This means BSI (Basic Safety Insulation)
- Don't lick it
Note the wire. I use it for holding up the plane body in the water stream for rinsing.
Step 3: Rinse
After ten minutes I rinse with fresh water and review only to find a bit more surface rust. I repeat.
Step 4: Edge Rebuilding
For rebuilding the edge I use water stones. Oil, diamond or sandpaper all work equally well. I also use an edge guide to hold a constant angle across all the grits. (220, 800, 1200, 4000, 8000). Once finished with the edge I repeat the process starting from the 1200 grit stone on the face of the blade. Once the edge and face have a nice polish I finish off on a chunk of leather primed with polishing rouge.
Step 5: Shavings Means Happiness
Once I have cleaned off all the Naval Jelly I rub beeswax on the bare metal and put the plane back together.
