Removing wheels from sprue question..

Hello Everyone,
I have a simple question, one in which I don't know the best answer. How do you all remove wheels from sprue and then remove the "plastic burr", if that's the term, without causing a flat spot on the wheel? I use a sprue cutter to remove the parts but rarely can I get the "burr" off without causing some sort of flat spot making the wheel "out of round"?. I would love to see a step by step, I am very visually oriented. Or any advice or tips would be very much appreciated.

Best,

Walter

Remove them, with sprue cutter. Buff burr off, with 2000 grit pad.

I find it quite useful to have a flat spot on tyres; makes it look like the model has some weight (providing, which is not always the case, that I remember to fi the finished wheels with the flat spot down).

I attach wheels or other round parts to a low speed Lego motor with blu tack and/or a cocktail stick/toothpick and then hold different grades of sand paper to the part.

I didn't even know a Lego motor existed, but will definitely pick one up. Thanks for the heads up.

Cheers,
Peter

Works and it stands up too. Just put an adjustable clamp on the trigger to adjust the speed and a tapered dowel in the chuck to hold the wheel.
