Was wondering, is it possible to re-sharpen a table saw blade without having to buy something like a 'jig'?
Blade in question is a Diablo 10" x 40T
I know they only cost about $30, but I'd like to get a little more life out of it. Have only used the blade for maybe 1,000 pen blanks? And with funds being 'tight' while on WorkComp....you know.

Technically, yes, with a diamond hone of some sort and some very careful honing.
You might try cleaning the blade to see if you don't get much improved performance. Crud builds up on the teeth of the blade really screwing up the cut.
There's all sorts of stuff that works for cleaning blades from oven cleaner to Simple Green to stuff made special for cleaning them. I find that Windex works fine for me, and I like the smell, unlike the oven cleaner I used to use. The lid to a Homer Bucket works as a container. Just spray the stuff (whatever cleaner you choose) on each side of the blade, let it sit a few minutes soaking, then use a plastic brush (or maybe a metal one if you like) to scrub away the crud. It comes off pretty easy with the Windex. Then rinse, Dry, and try it out.

Yep, what Jerry said.
It's amazing what a good cleaning will do for a blade.
I'd go that route before I tried any honing.

Scott,
I've not cleaned a blade yet but have read several discussions on it - most agree that a clean blade will give noticeable improved performance. Try it and let us know if it worked.
SEE - that's why I love it here, you learn crap all the time. I never even thought about using the top of a Homer Bucket to put the blade in - and actually..... a saw blade is surprisingly awkward because it's wide but you need a real shallow lip pan so you don't waste a bunch of cleaner.

I used that simple orange stuff from CDT, and I wasn't happy with it...there was a lot of crap on the blades from cutting that pine and spruce resiny wood, so I really need to try something else...

Cool!! Was really dreading the thought of having to file/hone each tooth of the blade....
I'll give the window cleaner a try, or maybe even the S.Green stuff and give it a spin. It does look a little dirty.

I'll send you a new one if you pay for the postage. It's an Irwin I got on sale. If you need it, it's yours. Nice, new, carbide tipped teeth & all.

Figure the sides of the teeth need to slide through the kerf created by the leading edge of the tooth, and there may or may not be any taper from the cutting edge back, so it don't take much crud at all to create added friction there.

A cheap Dewalt. Just can see throwing away something that should have lasted longer... Guess cutting green wood probably isn't a good idea? The blade cleaned up pretty good, I'll swap it out when the cheapo Dewalt blade gets bad. Scott (maybe I should've made a clock out of it) B |

I finally used all of my 2050 by CMT for cleaning blades. Woodcraft carries the stuff for $12.
I put my blade in a plastic paint roller pan. Then spray the 2050 on the teeth. After a minute of so, I then brush the teeth with (What Else?) an old tooth brush. It doesn't take much effort. Then flip the blade over and repeat.
If LOML is home, I'll wash the blade with a hose, dry and then flood with either Lacquer thinner or denatured alcohol to absorb the water from the blade. If LOML isn't home, I'll use the hottest water I can stand in the kitchen sink and follow with the alcohol.
Every time I use the 2050, I'm amazed how well it works. For really gummed up blades I'll use paint thinner to get most of the pitch first.

Don't worry, I have done the same thing. But did you ever get caught? That is a story all by it self for another day!!! Scott (gotta go search what 2050 is) B |

He's got a girlfriend... but she lives in France. For some reason, that's not too hard to believe Tim ;D Scott, it is amazing how much it can help just to clean the saw blade. I have used Windex and an old (hehehe my old lady's) toothbrush to clean the TS blade. It can make a whole lot of difference. Doug (she thought the toothpaste tasted different for some reason ;D ) B |

Waited until the "one-that-must-be-obeyed" went to work this morning...got some warm water in the sink a poured in a good amount of Simple Green. Waited awhile, and attacked the blade with a nylon brush I found in the tool chest.
Cleaned up rather nicely, and yup...under all that crud, the blade was still sharp! Dried the blade, and applied some oil with an old rag. I'll swap the blade out when the other needs cleaning!

This will be my next chore. I never realized you could do this. I wonder how many blades I have tossed that just needed cleaning.  |
