Stump grinder teeth sharpening & re-tipping

[inthewoods]

Hi all, as per title can anyone point me in the direction of a firm that can provide these services? Did my first stump grinding job today :-) but it was burning through the stump as opposed to grinding it! Have had a go with the angle grinder but to no avail :-( Cheers in advance.

You can sharpen many of the teeth yourself.

Provided you can get at them (the multi tips can be hard work).

I personally use a bench grinder witha standard grit wheel at one end to grind down the steel area just below the carbide pad. then I grind the carbide with the greenstone wheel.

 

I don't use a jig - just do it by eye (through goggles obviously).

 

Many swear by diamond wheels with an angle grinder but i prefer the bench grinder.

It also helps if you have a powerful bench grinder (I have a sealy 600watt machine which runs 8 inch wheels) it can be quite quick.

Shane, do you wear a respirator? Those green wheels produce a lot of dust, it doesn't look like you'd want it in your lungs.

a few places on here selling metal composite grinding wheels to fit angle grinders have the benefit of less dust than a bench green stone plus you do not need to remove the teeth to sharpen them

Not removing the teeth must be a big benefit. I found the stock removal was faster with a diamond disc but never really worked out if there was a cost benefit over the green grit. I always used the green grit outside.

Cheers guys but I don't have the time or inclination to do it myself atm, just need a firm to do it for me + I've got a spare set that need re-tipping.

You need to get a diamond faced disc for your angry grinder or a green silicone carbide wheel on a bench grinder and you can do them easily yourself.

personally find it easy and quicker to sharpen insitu than struggle removing and refitting worn and over tight bolts

Ended up buying a diamond disc for the angry grinder off of eBay, what a difference between grinding & just burning through it! That aside, have any other idiots been working on the sabbath?!

I found those diamond discs pretty ineffective and hard work.
