Carbide sharpening -- Do you do it and HOW?

[yamadoo]

I have a set of 10 inch carbides that have a ton of metal left, yet they are dull. Any thoughts?

There is a carbide sharpening wheel....I think that they are big bucks.

A friend of mine has one.....it was given to him.

We use it all of the time.....he has never bought a set of carbides since!

I have been resharping mine for alot of years,and there is a set up that we used to use for the oval track years ago,the wheel was wide and only about 3" in dia. and it was mounted on shaft seperate from the motor with a bracket to hold the skag in place to grind 10 plus inches of race carbide,now that was easy,but now its all manual,no holding devices to help you,but it can still be donr quite easy on a single runner carbide,but i am not sure how one would do it on woody dullies,or any dule carbide that cannot be seperated. As far as a wheel,go to any welding shop,or just order one from hi performance engineering,i use the 1/2 by 6" green wheel #agw-400 price$ 21.95 and now i see they have one you can bolt onto a hand held grinder,like body shops use,it is thin and 41/2 dia. and can sharpen carbides on the ski,so i bet you could do dullies with this set up,you could angle it enough to get in between each other part number is agw-4500 price is $6.95 now thats cheap enough ha lol good luck.

I've never sharpened them, just wore them down and tossed them.

Just go to a tool supply place and get your self a green silicon grinding wheel. Its the only thing that will sharpen carbide steel. They are not that expesive about 20-30 cdn, and you can get a few good sharpennings out of each set of blades. Been using one for years. Its works great.

Thanks guys

I bought the sled used with 10 inch, always been 6 inch and throw them away guy myself like alot of you.
A green grinding wheel sounds like a challenge to get straight. I think I will try it and if I and screw it up call Scott bergstrom or wait for Haydays.

Sorry, they are still on there. I've got 5000 miles on them. I'm getting a new sled, I can't afford new skags right now.

The ten inch sounds heavy. Bet your arms are in good shape. But those wheels are great. I will get at least 3 sharpenings out of each set of blades. More than pays for itself.

Any tooling reconditioner in your area will have no problems sharpening those blades for you. Carbide is finicky about how much heat you put into it. If you put excess heat in it the braze will some times let go as well as reducing the actual hardness of the carbide. Any tool & cutter grinder could easily sharpen. Also the grinding dust is extremely toxic. Take it to someone who knows what they are doing.
