Bar maintenance questions

A file grinder is ideal. 60 grit ceramic belt works well for me. 
 

Milwaukee do a nice cordless one. https://www.powertoolworld.co.uk/milwaukee-m12-fbfl13-0-12v-13mm-brushless-belt-sander-file-body-only

Use a bench grinder........with 25 years of experience doing it.

Often see mower repair shops try to use a bench grinder to sharpen mower blades too…

I use a flat file on standard bars or a wet stone on the Sugihara/Tsumura type bars, takes very little time at all.

What the hell kind of burrs are you creating that require a grinder?

We get quite a few smart arses collecting rotary mowers that have been in for service, peering underneath as we help load it up and telling us to unload it as we haven't sharpened the blade..........true the underside of the blade doesn't look sharpened...because you only sharpen the upper (hidden) side at the 30 degree angle required. I just tell them to lift the deflector flap up and peer inside at the blade and they will see it's been done properly. One guy wasn't convinced and even told us to sharpen the underside before he would pay!

I'm a bit confused too, only ever needed a quick go with a flat file on my bars. Maybe a bit of draw filing to sort out burrs on top of rail but nothing that needs a grinder.

More to do with dressing the bar rails to level them up on the top due to uneven rail wear...not the mushrooming on the side of the rails

I use a guide bar dresser, still only takes a minute. If your rails are becoming that uneven, that often, you need to take a look at your sharpening.

We use a belt sander at work. The boss has always done it this way and has been repairing saws for 60 years. I always did with a flat when I was on the opposite side of the counter. I know @pleasant pain with mower blades .

I always use a flat file and a small square for chainsaw bars.
 

For mower blades I use a big angle grinder to remove any dings followed by a flapper sanding disk on a smaller grinder to refine the edge.

Belt sander would be grand for touching up wedges as well when they get a bit out of shape also

 

if anyones got any recommendations for one send them through. Looking at this one right now.
