Electric chainsaw sharpener

[Bluebird]

I have a cheapo bought in Lidl and it has worked well for a couple of years. However recently after a few minutes use the grinding wheel makes an abnormal vibrating sound. I have cleaned everything out, turned wheel around but no change. This is the second wheel I have used and there appears plenty of life left in it. Any advice will be appreciated.

Is the wheel a proper size for the unit ? It may have a larger centre hole and be running eccentrically.

Or wear in the bearings or the shaft of the tool perhaps ?

Dress the wheel to regain sharp abrasive and remove metal stuck to wheel ?

Hold the centre boss and move up and down to see if there is play in the output bearing. Make sure the power is off!!

This is what I came here to say 😂 

 

If you're lucky it'll be running on sealed bearings and they'll be easy to get at. Whether or not £10-15 on decent bearings and potentially an hour or twos fiddling and testing is economical compared to buying another one depends on how much they are new though.

Plastic chain grinders are junk.
Totally inaccurate.

Same goes for drill grinders.

Thanks for most replies. I seem to have solved this with the help of an O ring.

Only in hot weather  My Lidl grinder works fine for my weekend warrior activities cutting rough and dirty timber.
