Hi.
I was in the local council tip shop last week and they had dozens of weights from 1kg to 10 kg from small bar bells that people have given up exercising with. The centre hole is about 25mm but a bit of creativity with some plastic tube to make a bush of the desired size, 18mm or 20mm would not be difficult.
Check your local council tip reclaim centre, it's surprising what can be found there that can be re- purposed to astro related projects.
