Its a Simonds Hand saw. It looks like they stopped producing saws in 1926, so I just know its probably older than that. It was in pretty good shape, so it didn’t take a lot of restoration.
I didn’t do a great job documenting the processes but it went like this:
For the blade -
1. remove handle
2. soak in evapo-rust
3. hose off evapo-rust
4. wet sand with 600 grit and wd-40
5. Cover etch with painters tape to protect from wire brush
6. wire brush with fine wire wheel
7. a little more wet sanding with 600 grit and wd-40 to soften edge where tape was
8. Wipe down and oil.
1. sand. I started with 120 grit, ended with 500. Note the idea wasn’t to get rid of all patinia, just clean it up a bit
2. BLO. 2 coats so far. I’ll add a couple more.
Wire brush and hit with the felt wheel.
