Rust on a Plane Sole
Tom MacGregor, Vermont
>Snagged two type 10 Stanley bench planes at a yard sale for $10.00, a #3 & a #4. Tons of gunk & some pitting but looked restorable to user grade. The 3 turned out to have a cracked cheek so I upgraded the levercap & wood on a user type 11. Used electrolysis on the #4 body and lapped out almost all the sole pits, a few dots here & there and a very small patch at the tail remain. Let it sit for 24 hours and the rust comes back in the pits. I've done this before without having small dings & pinpoints rust right back up, any thoughts on this one? The shop humidity is @ about 60%.
