It’s been slim pickings buying antique tools the past few months. So much so, I had to close my eBay store and just list things when I had a few tools to sell.
Scrounging around my shelves in my workshop, I found an old miter saw I bought at one time but completely forgot about. It was in pretty rough shape when I bought it but the price was right. Being out of inventory, I figured it would be a good time to clean it up
If you know me, you know I like dipping old rusty tools imto a ctric acid bath for a few hours. The process works great on old cast iron plane beds but when I try it on saw blades, it turns the steel really dark.
I heard about guys who scrunch up a piece of aluminum foil and use mag wheel polish to buff out the rust using nothing but elbow grease. I have tried this method on previous saws and have enjoyed the outcome so much that I no longer dip my saw blades in citric acid.
I started with a piece of aluminum foil but the blade was so tarnished and rusty, that I decided to use a scotch brite pad instead. It took a lot of elbow grease, but I was happy with the outcome after a few days of scrubbing.
You can see the etching was saved using the mag + aluminum polish. Sometimes when you use sandpaper to remove rust on saw blades, you lose the etching as well. You can also see the oxidation on the blade from all the rust.
When I bought the saw, I thought it was a Disston but it turned out to be a Simonds saw for a Millers Falls Langdon Mitre Box. Turned out to be a nice find.
The handle was already in nice shape. All I had to do was remove the old cracked lacquer finish with paint removal gel and buff it with steel wool. Then I applied a few coats of shellac to it.
The saw cleaned up nicely and is ready to be put back to use. Just needs a quick sharpening.

All I find on my shelves is dust and a few dead bugs.

I used to have three full metal shelves (the kind you buy at Costco) full of antique tools. Now they just store mailing boxes, and junk from around the house.
