Are Circular Saw Blades Worth Saving?

[crokett]

The floor on my new shop is 1/2" OSB over 3/4". Between the tarpaper, nails and leveling compound in some spots I am chewing up circular saw blades on the floor prep. I suspect part of the problem may be the tar paper gumming things up. Is it worth trying to clean/sharpen these blades or just go get new ones?

David,

Use "disposables" on OSB. Save some of the blades. The steel makes good scrapers.

The glue in OSB eats circ saw blades...

Use oven cleaner on them to clean and buy cheap blade for this kind of work and

dispose of them. Bill

Thanks fellas. I won't plan to to keep these blades then.

Make clocks out of them... Sears used to.

As a follow-up, what do you guys do with dead blades that you do not plan to keep? Do your local recycling groups accept them or do they go in the trash?

I had a batch of miscellaneous cheap blades that weren't good for their intended use, but I have a hard time throwing stuff like that out. I happened to mention it to someone at some PTA function and they knew of a lady who paints on saw blades (both hand saws and round blades) and sells them at craftshows. I gave them a box of the blades and that was the last I heard. I don't know whether they ever got painted or not.

Anyway, my shop ended up with a few less old chunks of metal cluttering it up.

scraper? scrapper?

how does one make a scraper from an old saw blade?

I got the idea from "Make Your Own Woodworking Tools", by Mike Burton. Fox Chapel Pub.

He puts an abrasive blade in his table saw.

I was kind of queasy about such a blade in my precious BT3000. So, I used a 4" grinder, with some difficulty. I made the longest cut possible without hitting the arbor hole. I used my fixed belt sander to straighten the edge. I took the teeth off, but left the round edge.

I used the usual procedure to prepare and roll the edge.

I liked the feel of the round edge, when scraping a wide board. The additional thickness made it unnecessary to bend the scraper, and it didn't get as hot as usual. It held a hook really well.

I light of the "no pics, didn't happen" rule. My cop out it...I loaned it to a friend to finish a bench top. He "misplaced" it. Guess I'll have to make another.
