In our recent article on trouble shooting wood burn on a table saw, reader and tech/power tool/DIY blogger Jude asked: “So where can you get a blade sharpened? I’m forever burning lumber and think my setup is pretty squeare.”

My first thought was Scott Whiting, who’s an active and respected member of Woodnet. (Here’s Scott Whiting’s blade sharpening rates over at WoodworkersZone) As a Woodnet regular I see him posting a lot and offering great feedback and advice.

My second thought was… well, can you do it yourself?

In this short post I share what I learned on sharpening carbide tipped saw blades yourself and then provide a list of potential saw blade sharpening operations for you to try out.

DIY Carbide Tipped Table Saw Blade Sharpening
My first recommendation on DIY blade sharpening is that you don’t fool with it. For one thing I read that blade sharpening is a trade skill. In addition, carbide tipped blades have complicated and exacting angles that must be perfect for safe operation.

Time and again I read warnings that people NOT try to sharpen their table saw blades on their own. And lots of reminders that you try cleaning your table saw blade first… From what I picked up sharpening yourself is kind of like doing home dentistry. Possible, but not recommended.

For those of you who haven’t already skipped this section to move along to the list of blade sharpeners, here are a few of the tips and pointers I found out there.

1) You’re probably going to be better off “touching up” your blade rather than giving it a full on sharpening. If you’re touching up your blades you should still count on sending them off to the sharpeners periodically. And at the expense of dignity I have to admit that I’m ignorant of whether or not “touching up” and “sharpening” are actually the same thing… My impression is that they are different.

2) You will need a diamond sharpener, because carbide is as hard or harder than any non-diamond sharpeners. My limited understanding is that 320g diamond wheel is a good place to start.

3) Mr Scott Whiting in the Woodnet forum doesn’t recommend against doing it yourself, though in a thread on a $75 sharpening machine he says: “Based on what my learning curve was 19 years ago plan on using up about 10 blades before you get acceptable and maybe 100 before you get good. Having somebody teach you would cut that way down.”

4) So from Whiting you can see that getting a teacher would be a really good idea if you’re serious about sharpening your blades yourself. So would having a good supply of dull, inexpensive carbide tipped blades and lots of spare time.

5) This Harbor Freight 120 Volt Circular Saw Blade Sharpener is what started off that discussion I keep referencing here. This is the tool that Whiting cautions you will need 100 blades to get good at using.

6) A Mr. John Paquay offers this advice in his short article Dealing With ‘Dull Carbide’: “Hone the flat, leading faces of the tips, taking care to keep the hone flat against the face of the carbide. Unlike HSS blades, carbide blades cut along the sides the teeth as well as along the tips, so be careful not to round these edges over as you work. Do not attempt to hone the side faces of the carbide tips — those edges will naturally sharpen as the face of the tooth is dressed. When you’ve finished honing the tooth faces with the fine or ultra-fine paddles, you may find it necessary to just touch the top of the tooth with the extra-fine hone. If you choose to do this, again be very careful to just barely polish the carbide. Any more than that and you risk irreparably changing the shape of the tooth. At all times, take care to keep the hone flat against the surface you’re dressing.” His is the only full on “how to” I could find out there. I recommend it for those of you who are going to give sharpening a go.

Again, I don’t recommend that you sharpen blades yourself. If you do, let me know how it goes :) Good luck and be safe!

1) Find the Locals
Check your yellow pages, check your hardware stores, ask the local cabinet shops. Go local because you will save time and money on shipping. Some hardware stores outsource though, which will add that shipping cost back on. Try to find the guys who actually do the sharpening.

2) Scott Whiting
A regular contributor at WoodNet, Scott Whiting has made a solid name for himself there and looks like the go-to sharpening guy for many of the regulars.

You may have to actually join the forum and send him a PM (private message, it’s how you send email to forum members).

4) Ridge Carbide Sharpening Services
According to a post in LumberJocks, the owner of Ridge Carbide recently contributed to an article on blade sharpening in Woodworkers Journal (WJ got 9th in our recent woodworking mag review) I think that’s a good sign! I saw a number of positive remarks about Ridge Carbide.
