I took a look at my runners today cause I thought that this is an area I kinda neglect. I have 6 inch carbide runners (not sure what brand) on it. 1998 zr600.

Now, here's what I found - The carbide portion has lots of meat left to it but it has ground so it is not very sharp anymore.
Can I take a dremmel and grind it back to an edge?
Eventually I will replace them, probably with shaper bars, but for now I seems like there is lots left there and replacement would be a waste.

Thanks guys.

Please forgive me if this is a dumb question.

It's actually a pretty good question and there is no harm in trying.

Even though I've already bought new ones, I'm going to try it.

Thanks.

I have same sled and my runners are rounded too. There is green wheel from woody's you can buy to sharpen your carbides. It should fit most 6" bench grinders. I plan on getting one soon and will try to get before and after pics of how it works.

I would not grind on the carbides, You will find that it is extremely hard , And why take away material you paid good money for. Back In 93-95, me and a few fellow riders that worked together thought abought this, and grinding carbides was not the answer, They have a Rockwell hardness of 65-70, Cant remember exactly, but almost like a file, We bought a roll of Lincoln 60, (Welder wire) at that time was the hardest a person could buy, and ran strips of weld where the hard weld is on the wear rods, as it is almost impossible to weld to the carbide itself, WE used to grind it to a V but it took alot of grinding discs, but we didnt pay for it..LOL The stuff was unreal ! To this day I still dont buy replacements for years in between....

as for your question yes u can sharpen them we do it all the time,as for mig welding we did that back in mid eighties,but now carbides are rather reasonable in price. but if i were u instead of mig welding them ,,,tig weld them u can take em to a weld shop and tell them to use hard rods.but remember for the cost and hassle of everything you can just buy new carbides hope this helps

Yes you can sharpen them. I do mine to keep them sharp. But a Dremmel won't touch them. The carbide requires a Green wheel or a diamond wheel.

Back in the day, my Dad would take stainless welding rod, knock the flux off them and weld the whole rods on. He would weld two side by side and then one on top of them. Worked great for a couple months or so. Now I sharpen mine with the carbide green wheel. Ron.
