What to do with old saw blades

[Scimonetti]

I accumulated around 15 old circular saw blades for 5" to 10" over the last few months.
Some have vibration reliefs, some don't and some are plain steel but all of them are unsafe to use. The carbide tips are chipped, falling off or the whole blade pitted.
I already started to make a shop clock from an old 24 tooth one, primed, sanded and painted. I also have plans to try to make a few different knives out of the old hardened steel.

Other than that, any ideas? Make scrapers? More clocks?

 

[G_P]

I've heard of people making knives out of them.

 

[jakemac]

Donate them to someone who paints and let them use them as krafty kanvases.

 

[mdbeck1]

Drop them in the scrap metal bucket for the next trip.

 

[paulsomlo]

I use one for the sacrificial part of electrolysis cleaning. They have lots of surface area and a convenient hole that I can hang them from.

Polish or paint in theme of your favorite brand (SnapOn, Craftsman, Ford, Chevy, Mopar, or whatever) . . . and make into a CLOCK.

Innerds of clocks are cheap and round saw blade is perfect for clock.

 

[NY_treeguy]

Use the carbon steel blades for blades. Plane blades, spokeshaves, marking knives, etc. Soft enough to work but hard enough to take an edge.

They're consumable tooling. Throw them out.

Save them for cutting shingles at the ridge vent when re roofing.

Beyond that I save them, never know when I might need one for something else. Maybe resharpen?

 

[rockinacummins]

I had about 100 of those when I cleaned out my grandfathers shop. Hauled them across the scales.

I wanted to have a couple painted but nobody was interested.

 

[NUTTSGT]

Drop them in the scrap metal bucket for the next trip.

I've already done that with a couple of blades.

 

[Shadowdog500]

Mine go into the recycling bucket and are replaced with new.

I had an old shopsmith on permanent loan for a while that used a unique blade that shopsmith wanted a fortune to replace.. I hand sharpened the blade with a file and was suprised how well the re sharpened blade worked.

Those blades would all make *really* nice locking washers for really big bolt heads on like oil rig platforms and such! You don't even have to remove the teeth as they are the *locking washer* feature! - Paul

 

[pendragon1998]

I might stick a few under my bench for the next time I come across one of those 'trade in an old blade and get a new sample blade' promos the blade manufacturers occasionally run.

Using them for target for a .22 or a pellet rifle

 

[alwaysFlOoReD]

Play frisbee with your not so favorite neighbor.

 

[geologist]

You could slot them and weld them into an X pattern, then build a stem, paint them up, and have some neat looking metal flowers.

 

[sometoyotaguy]

Working on a Craftsman one today! 24t makes it easy to divide the hours. I have access to a laser cutter and engraver so I'll probably stencil the numbers and cut some vinyl logos? Not really sure yet but am hitting up a flea market looking for old clocks today.

Any craft store has clock movements along with the hands.

 

[Gotcha640]

Use them as a hammering surface for small parts on a wooden work bench

 

[UroWerks]

Turn them into clocks and sell them on eBay maybe even make em personalized

 

[Jure]

a knife

 

[alfazer]

Look good on the end of a spike sticking out from the wheels of a car. Like some kind of Roman chariot or mad max weapon. Or maybe a sundial.

 

[toolmiser]

Probably not worth the effort, but I read on a homebuilding site that the carbides are worth a lot more than the rest. Don't know how to remove them though.

 

[pauls_workshop]

They would also make really nice coasters for a giant size coffee mug!

I like the portable anvil idea. If you don't have a real anvil, these would do in a pinch to pound on. - Paul

I've got a stack for that same purpose. I missed the last ones at Lowe's

 

[MaineGuide]

I take any that I find, and hang them on the outside of my barn/shop. The focal point in the shop is the Unisaw, so I think it's a fitting theme.

 

[pauls_workshop]

Forget just outside the barn/shop, heck, hang them off strings all around the outside of your house and property. Put a few hanging from like a wooden engine stand too in the yard. No people will bother you again! It would be like people used to do when they would leave skulls in various places to indicate you were crossing their boundaries. All your existing friends would still come by because they know you are mostly alright, but it might be harder to make new friends. - Paul

 

[Engine]

Same, maybe a good torch to undo to brazing. If I stumble upon more I'll look into it.

Carbide Processors may buy the carbide tips, if you have enough to make it worthwhile to go to the trouble of detaching them and shipping them to CP. Here is link to their buying page.

 

[pauls_workshop]

Good idea, I could even go one step further and form a gang that uses circular saw blades as a symbol. After we committed these crimes we could leave old blades at the scene. The possibilities are endless.

I DO like how you think!! - Paul

 

[gungatim]

I make knives out of them, but if they have carbide, I remove that and scrap. get like $11/lb for carbide...

 

[cheechi]

Probably not worth the effort, but I read on a homebuilding site that the carbides are worth a lot more than the rest. Don't know how to remove them though.

cut through some nails and the carbide will be off them for sure.

Lathe Carbide Cut off Parting Tool from Saw blade

 

[Greasymofo]

Using them for target for a .22 or a pellet rifle

That's exactly what I use them for.

Lathe Carbide Cut off Parting Tool from Saw blade

Now that is rather brilliant!

How about Wood Lathe turning tools too? - Paul

 

[pauls_workshop]

Seems like it works great! I do not have a metal lathe but do mostly wood turning. That got me thinking about a detailing tool for small work, maybe pens. I have made an Oland tool from old hss cutting blanks. I can't picture how I could attach it, still thinking

Yes, I'm thinkin a precision wood lathe turning tool using the carbide tip would be pretty awesome! We need someone who can cut with a plasma torch! I want one too! - Paul

 

[Fugio]

I also use them as .22 and airgun targets. They make a really decent "ping" sound when you hang them out in the trees at a distance.

My son likes to throw them at huge blocks of styro-foam. Redneck ninja stars.

Nice little stack of them you have there. Don't try to put them all on a saw at once to make a redneck dado blade. Learned that one the hard way about 30 years ago.

 

[Fugio]

Oh how about this?!

Next time there's a big storm with a tornado, run outside and toss them up into the air and just see what happens!
Maybe even write your name and address on them and ask whoever finds one to contact you so you can map out how far they flew!
People will marvel at your love of science and will applaud your informative, yet madcap antics!

 

[pauls_workshop]

I think a cutoff wheel would work fine? Maybe even a dremel.

I've done dremel cut off wheel work before. It is ok for really thin steel, but the thick stuff is hard. Grinder cutoff wheel would work much better, but the plasma torch is so much easier and elegant! - Paul

 

[404]

If possible draw the line to be cut out on both sides of the blade. Then use cut off wheel from both sides and meet in the middle of the thickness. Easier on the cut off wheel that way.
