I’d recommend having it professionally done. I would not attempt to sharpen a high quality blade myself, and cheapo blades aren’t really worth having unless you’re cutting firewood. $15-$20 once a year or two (for me) gains you access to some very expensive, very precise machines.

I have to agree with Knotscott.

This is not for the home woodworker. I have been woodworking for 60 years and I still wouldn’t sharpen a really nice table saw blade by hand. If you live far away from a sharpening service, make a mailable reusable container for the blade and send it off to a reputable professional saw sharpener like Forrest Blades in New Jersey (http://www.forrestblades.com/). I recommend having two or more blades for your saw. When one gets dull, send it out for sharpening and use another blade. And one more tip. To clean the pitch and gum from your saw blade use plain old oven cleaner. Works like a charm!

This thread piqued my interest ,found these two videos very interesting to watch,Just to see what’s involved in sharpening a 10” blade you should see the machine that’s used to do the job properly,you maybe able to sharpen the face of the carbide teeth but sharpening the bevels needs another machine/another totally different set up.

My local wood supplier turned me on to his blade sharpening service.

Just ask them.

HF has a blade sharpener that’s not too expensive, especially with a coupon. You could give it a try with an inexpensive blade to see how it goes, before tackling an expensive blade.

I have that harbor freight unit. It does work well, but I only use it to sharpen up cheapos that use for processing pallet lumber. For that it’s fine, I will not try it out on my ridge carbides. It has a diamond wheel for carbide tips and another stone wheel for steel blades. It does a great job on steel, so so on the carbides.

I consider myself to be fairly handy, from woodworking to having rebuilt a few car engines in my time, and painted a few cars to boot, and I would never, even on my best day, think I could accurately sharpen a 10” carbide saw blade.

I didn’t want to have to do this, but I guess I have to refer you to this video on youtube that shows you exactly how to do it yourself, for cheap, too. Unless you count the cost of the new blade your gonna need after you’re done!

Man, that video was,,,,,,enlightening. At least the HF set up has an indexing pawl that lets one take a semi consistent grind on each tooth.

Most of the DIY models I have seen only allow you to grind one face\surface.

Send it out.

Unless you have a diamond wheeled carbide sharpening machine (cost $2000 +), don’t even consider it. Send it out. I have such a machine and do my own blades. I know it would be next to impossible to do a good job without one.

Long ago, I used to sharpen steel blades with a file. I made a blade holder that sandwiched the blade between 2 pieces of plywood, with a bolt through the arbor hole. Loosen the wing nut and rotate the blade for the next tooth. I had a Craftsman Chromedge “planer” blade (hollow ground) that I kept going for years before retiring it. Usually took me about 20 minutes to sharpen the whole blade.
