This saw plate is remarkably well preserved for its age, but it could benefit from a clean. I gathered the stuff I thought I might need, but all I used was the 3-IN-ONE degreaser foam, the Hammerite Rust Removal Gel, the green scouring pad, kitchen roll, and wet and dry paper (more than you see in the picture below).
I start by spraying the plate with the degreaser. I have found that the rust remover works better on the first application if the surface has been degreased first.
Wait 5 minutes…
Wipe the surface with kitchen roll. Then repeat for the other side.
Apply the Hammerite Rust Removal gel liberally.
After 20 minutes I dip the green scouring pad in water…
…and gently rub along the length of the plate. The black staining and any rust comes off in no time at all.
Then I washed the surface with a paper towel dipped in clean water and repeated the process on the other side of the saw plate.
With the rust and grime removed, it was time to start polishing the plate with wet & dry paper used dry. I went through the grits using long strokes along the plate. The grits used were P120, P180, P240, P320, P400, P600 and finally P800. I used a wooden block with the P120 and P180 grits. The other grits were used without the block. This was the result.
I like a shiny saw plate on my back saws. I use the reflection in the plate to line up my saw cuts so that I know when I’m cutting at 90 degrees and 45 degrees without having to mark the wood.
I might polish this a little bit more, but my arms were aching so I called it a day for the time being.
In Part 3, I turn my attention to the saw handle.
Thanks for watching.
