/diy/ - Do It Yourself

I thought about asking >>>/sci/ this but I think /diy/is usually more helpful

I like loose leaf tea and the latest batch I've acquired is of poor grade. The sediment in the cup is tea dust and when suspended in the tea makes it quite bitter. I've tried fine I've tried filtration but that doesn't work well enough. It takes 30 minutes or more, for enough to collect at the bottom of the cup so it doesn't affect the taste, but then the moment you pick it the cup the sediment becomes stirred back into the cup. So I thought maybe a centrifuge is more efficient, and then maybe some way to separate the clean tea from the sediment tea at the bottom.

My question is:
How difficult is it to build a centrifuge? I'm not trying to make yellow cake, just a descent cup of tea. Can I just slap some adjustable counterweights on a spare electric motor and call it a day? Do I need special bearings or will any off the shelf bearings do the job?
